Investigations of microbial growth, denitrification, nitrogen fixation and mycorrhizal research are now very active research areas involving a great deal of biochemistry as well as biology. These areas of investigation show great potential for the use of soil and its components. However, scientific discussions concerning them are occurring largely under the auspices of agencies other than the ISSS. The practical utilization of knowlegdc in these fields must, however, involve soil scientists and these subjects should be adequately covered at the ISSS Congresses and ISSS sponsored meetings. One of the initial steps that could be taken to recognize the above significant components in soil science and to attract scientists working in these areas to our Society would be slight alteration in the name of Commission III. The suggestion for a new name is Soil Biology and Biochemistry. It was the opinion of most of the people who attended the Commission III business meeting at Edmonton that this reflection of modern trends would not alter the excellent cooperation and relationships with closely allied commissions such as Soil Chemistry and Fertility. It should, however, greatly strengthen future meetings of Commission III and the ISSS. The proposal for a change in the name of the Commission requires a change in the rules. This can only be done by a vote. Preliminary to requesting a vote, the executive of Commission III has contacted a number of people in ISSS. The majority of chairmen of other commissions were in favor of a name change to take into account the changing aspects of soil biology and to attempt to attract the more biochemically oriented scientists to our international congresses. Some reservations concerning the conflict of interest with Commission II which has handled much of the humic acid information during the congresses were brought forward. Some people also believe that the name Soil Biology now adequately describes the activities of Commission III. It is hoped that the possibility of a name change and more importantly the requirement that the exciting areas of interest such as microbial growth, denitrification, nitrogen fixation and mycorrhizal research be represented at our congresses be further discussed by the members of ISSS. Points of view will be discussed at the meeting in New Delhi, February, 1982, and your comments would be appreciated. If you cannot attend the meeting, we would be interested in receiving your viewpoint by letter. E.A. Paul Berkeley, California, U.S.A.

SYMPOSIUM ON MICROBIAL ECOLOGY The Third International Symposium on Microbial Ecology will be held August 7-12, 1983. at Michigan State University, East Lansing, Michigan. U.S.A. This symposium is an official meeting of ICOME. the International Committee on Microbial Ecology. The aim of the symposium is to assemble microbial ecologists with interests in a wide range of habitats so they can discuss the interactions of microorganisms and the underlying processes that regulate these interactions. The symposium program will include lectures by keynote speakers, plenary sessions, contributed papers (both oral and posters), and round-table discussions. Those wishing to receive more information should write to: Third International Symposium on Microbial Ecology, The Kellogg Center for Continuing Education, Michigan State University, East Lansing. Michigan 48824, U.S.A. 4 ISSS Commissions IV, V, VI and VII Report on the INTERNATIONAL CONFERENCE ON SOILS WITH VARIABLE CHARGE Palmerston-North, New Zealand, February 11-18, 1981 This official ISSS inter-Congress meeting was organized by the New Zealand Society of Soil Science and the Royal Society of New Zealand, in cooperation with the Soil Bureau of the N.Z. Department of Scientific and Industrial Research (DSIR). It wasa great success, both as regards the organization, the number of participants, and the depth and breadth of the subjects treated. There were around 300 participants, of which 130 from New Zealand itself. The other 170 came from 35 countries, with sizeable delegations from USA (32), Australia (26), China, Japan, Malaysia and Canada (each 9). They included the President of ISSS, Dr. J. S. Kanwar, its Secretary-General, Dr. W. G. Sombroek. and the Chairman of Commission VII. Prof. Dr. U. Schwertmann. The Conference took place at the Campus of Massey University, where also accommodation was arranged. It was in fact the second time that an international soils conference was hosted here; the first was held in 1962, as a joint meeting of Commissions IV and V, at the occasion of the completion of the mapping and classification of the country's soils on a national basis. The present Conference was in part meant to celebrate the 50th ( !) Anniversary of the New Zealand Soil Bureau. The subject of the meeting was geared towards the genesis, classification, mineralogy, fertility and management of three main groups of soils, viz. the Podzols (Spodosols) of temperate regions, the Andosols (Andepts) of volcanically active regions, and the low-activity clay soils of the tropics and subtropics : Ferralsols (Oxisols), many Acrisols, Nitosols and Luvisols (Ultisols and Alfisols). All of these soils have appreciable percentages of variable-charge components - i.e. electrical charges altering considerably with changes in pH and ionic strength composition of the ambient soil solution, due to relative abundance of clay minerals with amphoteric surfaces. The structure of the Conference was planned to link the use of these soils with an understanding of their properties. Consequently, the first halfwas devoted to a review of the new information on the characterization of soils with variable charge and the latter half to new developments in classification, management and transfer of information for soils with variable charge. The official opening of the Conference was performed by the ISSS President, who congratulated the organizers on the timely choice of the subject, and highlighted the achievements of a number of N.Z. soil scientists. Words of welcome were pronounced by Dr. A. Stewart, Vice-Chancellor of Massey University (and Chairman of the 1962 Conference). The review part of the meeting was much facilitated by the availability of a Conference book entitled 'Soils with Variable Charge', handed out to all participants at registration (see this ISSS Bulletin for post-Conference orders). This book, edited by Dr. B. K. G. Theng, contains a comprehensive series of articles, each by leading research workers in the subjects, on the morphology, mineralogy, chemistry, physics and mechanics, biology, and genesis and classification of the soils under discussion. The contents of the book were introduced and reviewed during the first day, by invited speakers in plenary sessions (Drs. R. W. Arnold, K. Norrish, G. Uehara, R. D. Northey, M. E. di Menna, J. A. Springett, and M. L. Leamy). The ensuing discussions 5 VMBRELmS FO*.

It nevertheless provided for a sound basis for the subsequent conference days, with a well-balanced alternation of oral papers, poster sessions, short tours of local institutions and countryside, discussion group sessions, International Committee meetings, specialists group meetings, and a symposium on agrotechnology transfer. A total of 18 oral research papers were delivered, and over 80 papers were presented at two afternoon poster-sessions. English language summaries of each of them had been rotaprinted in the Conference's booklet on "Programme and Abstracts'. The discussion group meetings dealt with Variable charge analysis, pH and CEC Phosphate and other anions Short range order minerals Biology and organic matter, and influence of clay minerals on the biochemical acitivity of soil micro-organisms - Clay mineral weathering - Genesis and classification: volcanic soils - Genesis and classification : tropical soils - Genesis and classification : podzolization - Engineering and soil physics aspects Forestry aspects - Soil interpretation Fertilizers and agronomy. These meetings were very lively affairs. The resulting summary reports, often with specific recommendations on research priorities, nomenclature, etc., have been communicated to the respective ISSS Commission Chairmen, for their attention and action. - The International Committee and specialists group meetings comprised 'Soil Research Needs in the South Pacific". "Land Reclamation after Mining', and the progress of some of the international committees supported by the USAID/SMSS programme to improve the US Systems of soil classification generally known as 'Soil Taxonomy' (ICOMAND, ICOMLAC. ICOMOX ; see ISSS Bulletin no. 57). Also, an introduction was given to the idea to develop an International Reference Base (IRB) for soil classification (emanating from a FAO/Unesco/UNEP/ISSS consultation in Sofia, May 1980; cf. Bulletin 58), which idea will be formally discussed at the forthcoming ISSS Congress in New Delhi, India. A full day was devoted to the presentation of the approach and the first results of the USAID Project of Benchmark Soils as a vehicle for agrotechnology transfer (programme of the Universities of Hawaii and Puerto Rico). Introductions were given by the project 'father' Dr. L. D. Swindale (ICRISAT) and the project staff. The impact of the agrotechnology transfer hypothesis testing in Brazil. Indonesia, the Philippines and Thailand were briefly described by soil scientists from those countries. The whole was accompanied by several posters in a permanent display room. In conjunction, the symposium provided for a useful introduction to the subject. One would however wish for a more in-depth discussion of the scientific principles involved, and a critical evaluation of the first results at the project's experimental sites, as recorded in its published progress reports (see this Bulletin), in view of the potential follow-up of the project. On the last day the implications of the soils-with-variable-charge Conference were discussed. As to the study of their physical and engineering properties Dr. I. J. Smalley 1 of the New Zealand Soil Bureau pleaded for attention to soil structure, aggregate stability, and the use of the traditional Atterberg limits at the study of particle interactions. Dr. M. E. Sumner of the University of Georgia, USA, gave a comprehensive review of the study on the mineralogy of the variable-charge soils (methods of fractionation, extraction methods of soil clay, nature of the soil surface, crystallinity, future research directions), as well as on their chemistry (concept of exchange capacity versus measured parameters, soil acidity, charge manipulation, research needs). The study of agronomic aspects in relation to the soils under discussion was critically examined by Dr. P. Sanchez of North Carolina State University, USA. 'Comfortable' aspects were felt to be the much better soil characterizations nowadays provided with agronomic experiments, and the realization that similar nutritional problems apparently occur in undeveloped as in highly developed areas. Uncomfortable is however the apparent lack of awareness of existing long-term management data, and the conspicuous absence of the plant itself as focal point of any discussion. He made a ringing plea to forge a bridge between pedologists and agronomists ('the topsoil is where the action is'), and better international communication between agronomists themselves. Finally. Dr. D. J. Greenland (IRRI) gave an over-all assessment of the Conference. He commended the organizers for the very useful structure of the meeting, allowing effective inter-disciplinary discussions between several ISSS Commissions. He also opined that in the field of pedology the 'anatomy' of soils has now largely been defined through the precise definitions and keying of the US 'Soil Taxonomy', but what is now lacking is an encyclopedia of their 'diets' or the 'doctoring of ailments.' He called for a comprehensive effort on terminology for other branches of soil science, like chemistry and mineralogy. The conference was then formally closed by the ISSS Secretary General. He expressed the thanks of all participants to the organizers, with particular mention of the Conference President Prof. J. K. Syers, the Organizing Committee's Chairman Dr. R. B. Miller, and its Secretary-General Dr. L. F. Malloy. A plea was made to the N.Z. Soil Science Society to have the full texts of the plenary papers and reviews, as well as the abstracts of the poster papers, published as official Proceedings of the Conference. The social ambience of the Conference was very lively throughout. A daily newsletter, called 'Varisol News' held everybody timely informed on upcoming programme items and changes, and printed many off-the-cuff summaries of discussion items. photographs, axioms, cartoons, etc. Evening functions were ample, well-organized and highly enjoyed by participants. They included an official reception by the Royal Society of New Zealand, a tour of local research centres, a film show, a wine-andcheese social event, a barbecue dinner, a New Zealand touristic promotion evening and a farewell social. The 'accompanying persons' were kept amically busy through a varied Ladies Programme, while they also got a general impression of the purpose of all that soil digging and analyzing through a lively evening conference lecture by Dr. Greenland. The meeting was preceded and followed by several excellent technical tours of varying length and emphasis (North-Island, South-Island, Western South-Island, North-Auckland). They were very well-documented by tour guide books, and the sizeable number of participants enjoyed the cnthousiasm of the tour leaders and a good balance between soils and scenery. Return travel by foreign participants was unfortunately marred by a lenghty strike at Auckland airport. There remained however a consensus that this was one of the best inter-Congress Meetings ever held in the history of the International Society. W. G. Sombroek. Wageningen Netherlands 8 A ISS-Commission V Compte rendu de la lime RÉUNION SUR UNE 'BASE INTERNATIONALE DE RÉFÉRENCE POUR LA CLASSIFICATION DES SOLS'. Sofia, Bulgarie, 17-19 juin, 1981 Après une discussion poursuivie pendant une année par correspondence sur les problèmes traités dans la première réunion, une deuxième réunion s'était tenue à l'Institut N. Poushkarov à Sofia du 17 à 19 juin 1981. Le cercle des participants fut légèrement élargi (par exemple du Brésil, du Canada, de la Chine, de la Roumanie, du Soudan et de la Yougoslavie). Les discussions portaient en particulier sur: 1. 2. 3. 4. 5. 6. les principes d'une Base internationale de référence (IRB): les unités aux niveaux supérieurs et leurs définitions; les principes de leurs subdivisions aux niveaux plus bas; la nomenclature; les critères diagnostiques (seulement tentativement); le programme de suivi. Les participants donnaient de nouveau leur adhésion à ce qu'une IRB soit indispensable comme un moyen de communication pour une classification des sols du monde et pour une échange mondiale des expériences et de l'information. Pour ceci on a prévu un système comprenant 15 à 20 unités au premier rang, qui seront subdivisées au deuxième à quatrième rang, et au delà du quatrième rang selon les besoins des pays concernés. Au premier rang la nomenclature sera descriptive (codifiée si nécessaire) et, au deuxième et troisième rang, on employera des noms. De préférence, des noms déjà existants seront employés (p.e. de la légende de la carte mondiale des sols FAO/Unesco) tout en respectant les définitions relatées à ces noms (seulement des noms 'abandonnés' sont 'libres' pour une rédéfinition !). Pour la caractérisation des régimes d'humidité et de température au quatrième niveau on pourrait employer la terminologie pour les zones agro-écologiques. Les définitions des unités au plus haut niveau seront révisées par les pédologues de la FAO et distribuées aux participants pour commentaire. Des horizons et propriétés diagnostiques seront utilisés selon la légende de la carte mondiale des sols, sauf pour les changements acceptés déjà ou dans l'avenir. On a approuvé que des fonds seront sollicités non seulement pour un coordinateur du travail des groupes différents, mais aussi pour des investigations sur l'aptitude de plusieurs méthodes d'analyses au laboratoire pour la détermination des phénomènes diagnostiques à l'ISM, et éventuellement pour l'appui aux institutions nationales qui sont actives dans ce domaine. Le futur travail sera dirigé par un Conseil d'administration composé des représentants de FAO, Unesco, UNEP et AISS et sera mené scientifiquement par un Conseil consultatif recruté parmi les membres du Groupe de Travail IRB à former dans l'AISS Commission V (les Présidents des Sociétés nationales ont été demandés déjà à proposer les noms des candidats pour devenir membres de ce conseil). Le Président de la Commission V donnera un rapport sur les résultats acquis jusqu'à alors à l'occasion du Congrès international à New Delhi 1982. On espère que l'AISS sera le forum scientifique pour le projet IRB comme elle l'était pour la légende de la carte mondiale des sols. E. Schlichting, Président AISS- Commission V 9 Report on the lind MEETING ON AN 'INTERNATIONAL REFERENCE BASIS FOR SOIL CLASSIFICATION' Sofia, Bulgaria, June, 17-19, 1981 After a one-year discussion by correspondence on the problems treated in the first meeting (see ISSS Bulletin No. 57, p. 19/29), a second meeting was held at the N. Poushkarov Institute in Sofia from 17to 19June 1981 with a slightly increased circle of participants (e.g. from Brazil, Canada, China, Romania, Sudan, and Yugoslavia). The discussion was centred around: 1. the principles of an International Reference Basis (IRB): 2. the units at the highest levels and their definitions; 3. the principles of their subdivisions at lower levels; 4. the nomenclature; 5. the diagnostic criteria (only tentatively); and 6. the follow-up programme. The participants agreed again that an IRB is needed as a means of communication for a classification of the soils of the world and for a global exchange of experiences and information. For this, a system is envisaged consisting of 15 to 20 units at the first level, which will be subdivided at the second to fourth level, and beyond the fourth level according to the requirements of the countries concerned. At the first level, the nomenclature shall be descriptive (if necessary with codes), and at the second and third level, it shall consist of names. Preferably existing names (e.g. of the legend of the FAO/Unesco Soil Map of the World) should be used, taking into account the definitions related to them (only 'abandoned' names are 'free' for redefinition !). For the characterization of the soil moisture/temperature regimes at the fourth level the terminology for agro-ecological zones shall possibly be employed. The definitions of the units at the highest level will be revised by FAO soil scientists and distributed to the participants for further comments. Diagnostic horizons and properties shall be used according to the legend of the Soil Map of the World, with subsequent changes that are already accepted or will be so in the future. It was agreed that funds shall be sought not only for a coordinator of the work different groups but also for investigations on the suitability of various laboratory methods for the determination of diagnostic features at ISM, and eventually for the support of national institutions working in this field. Future work shall be guided administratively by a steering committee, consisting of FAO. UNESCO. UNEP and ISSS representatives and shall be conducted scientifically by an advisory panel recruited from the members of the Working Group IRB to be formed in the ISSS-Commission V (the Presidents of the National Societies were already asked to propose the names of possible members). The Chairman of Commission V shall give a report on the results achieved hitherto on the occasion of the International Congress in New Delhi in 1982. It is expected that the ISSS will be the scientific forum for the IRB project as it was for the legend of the Soil Map of the World. Id Bericht über die II. SITZUNG ÜBER EINE 'INTERNATIONALE REFERENZBASIS FÜR BODENKLASSIFIKATION' Sofia, Bulgarien, 17. - 19.6.81 Nach einer brieflich während eines Jahres fortgesetzten Diskussion der in der 1. Sitzung (s. IBG-Bulletin No. 57, S. 19/20) behandelten Probleme fand in der Zeit 17. -19.6.81 im N. Poushkarov-Institut in Sofia eine 2. Sitzung mit einem etwas erweiterten Kreis von Teilnehmern (z.B. aus Brasilien, China, Jugoslawien, Kanada, Rumänien, und dem Sudan) statt. Beraten wurden insbesondere über I. die Prinzipien einer Internat. Referenzbasis (IRB), 2. die Einheiten in den höchsten Niveaus und ihre Definitionen, 3. die Prinzipien ihrer Unterteilung in niedere Niveaus, 4. die Nomenklatur, 5. (nur tentativ) die diagnostischen Kriterien und 6. das weitere Vorgehen. Die Teilnehmer stimmten wiederum darin überein, daß eine IRB als Kommunikationsgrundlage für eine Ordnung der Böden der Welt and für einen globalen Austausch von Erfahrungen und Informationen nötig ist. Dafür ist ein System vorgesehen, das auf dem 1. Niveau 15-20 Einheiten enthält, die in den Niveaus 2. 4. weiter unterteilt werden, auf weiteren Niveaus entsprechend den Bedürfnissen des jeweiligen Landes. Die Nomenklatur soll auf dem 1. Niveau deskriptiv sein (ggf. mit Zahlen-Codes), auf dem 2. und 3. Niveau durch Namen, möglichst durch existierende (z.B. der Legende der FAO/Unesco Weltbodenkarte) und zwingend unter Respektierung der mit ihnen verbundenen Definitionen (nur 'aufgegebene' Namen sind 'frei' für eine neue Definition!), erfolgen und sich zur Charakterisierung der Bodenfeuchte-/-wärmeregime auf dem 4. Niveau möglicherweise der Terminologie für die agroökologischen Zonen bedienen. Die beratenen Definitionen der Einheiten auf dem höchsten Niveau werden von den Bodenkundlern der FAO überarbeitet und den Teilnehmern zur erneuten Stellungnahme übersandt. Als diagnostische Horizonte und Merkmale sollen die der Weltbodenkarten-Legende verwandt werden, sofern nicht Änderungen schon beraten wurden oder es künftig werden. Es wurde beschlossen, daß Mittel angefordert werden sollen nicht nur für einen Koordinator der Arbeit in verschiedenen Gruppen, sondern auch für Untersuchungen über die Brauchbarkeit verschiedener Labormethoden für die Bestimmung diagnostischer Merkmale am ISM und ggf. zur Unterstützung entsprechend arbeitender nationaler Institutionen. Die weitere Arbeit soll durch ein Komitee aus Vertretern von FAO, UNESCO, UNEP und IBG administrativ geleitet und durch einen Beraterstab wissenschaftlich geleistet werden, der sich aus den Mitgliedern der bei der IBG-Kommission V zu bildenden Arbeitsgruppe 'IRB' rekrutiert (die Präsidenten der nationalen Gesellschaften wurden bereits um Namensvorschläge gebeten). Der Vorsitzende der Kommission V wird auf dem Kongreß in New Delhi 1982 über die bisherigen Ergebnisse berichten. Es wird erwartet, daß die IBG wie für die Weltbodenkarten-Legende auch für das IRBProjekt das wissenschaftliche Forum sein wird. E. Schlichting, Vors. d.

II ISSS Commissions V and VI Report on the INTERNATIONAL CONFERENCE ON 'ARIDIC SOILS' Jerusalem Israel. March 30 April, 1981 This joint meeting of ISSS-Commissions V (with the Working Group DS) and VI was prepared and conducted by an Organizing Committee of the Israel Soil Science Society under the guidance of Dr. Yaalon. Participants were about 40 colleagues from Israel and 70 from 15 other countries (regrettably few from developing countries because UNEP was unable to provide the promised funds). The 46 papers during 4 days covered a wide range, from geomorphological and meteorological problems of aridic areas, to the soil pattern in relation to relief or climate and soil forming processes in warm and cold deserts, to the ecological conditions and finally to problems of land use in dry areas. The meeting offered and excellent opportunity to get informed about geomorphological and climatological aspects of soil genesis, classification and cartography. The ecological aspects including land use were stressed less. The papers wil be published in special issues of CATENA and GEODERMA. The 23 posters, shown during 3 days, had an orientation similar to the papers and supplemented them. Since meetings as well as lodging rooms of the participants were in the Kibbutz Kiryat Anavim there was ample opportunity for talks within and outside discipline boundaries. This intense interdisciplinary communication was a special, very positive feature of the Conference. The history of the meeting place, the culture of the host country and the personal contacts between hosts and guests were also adequately treated. On two 1-days-excursions during the Conference and a subsequent 5-day-excursion semi-arid and arid landscapes and their soils were demonstrated, and historical sites were visited. In a sequence of Litho-, Luvi-, Xero- and Yermosols in the Judean Desert the influence of parent material, climate and age of land surfaces was studied. In the Jordan Valley the formation of Fluvisols and Solonchaks. especially in relation to relief (ground water level) was examined. During the postconference tour in the semi-arid Judean Hills and the Coastal Plain special sedimentological and paleopedological problems were discussed. In the Western Negev and in the Negev Hills with Areno- an Xerosols- methods of modern and ancient land use (reconstruction of a Nabatean farm near Ein Avdat) were observed and geomorphological investigations demonstrated. The route of the third day led from Sde Boger to Eilat through the spectacular Negev Mountains where Yermosols with desert pavement and varnish or accumulation of airborne solutes as well as Fluvisols with takyr formation were studied. North of Eilat a chronosequence of terraces in the Timna-Valley and of their soils was shown, while south of Eilat a rest with touristic attractions was made. During the fifth day problems of irrigation culture in the arid Arava Valley were discussed and a Fluvisol-Solonchaksequence on the Zin alluvial fan near Sedom was observed. At the foot of the old fortress Massada the participants thanked their highly qualified and deeply engaged guides. Dr. J. Dan, Dr. R. Gerson and Dr. D. Yaalon, for a sometimes exerting but most interesting excursion and repeated their thanks for the successful conduct of this very informative Conference. E. Schlichting, Stuttgart-Hohenheim.

An ihr nahmen etwa 40 Kollegen aus i>rae' u n d 70 aus 15 weiteren Ländern teil (bedauerlicherweise wenige aus entwicklun« lär| dern, weil UNEP die versprochene Unterstützung nicht gewähren konnte). Die 4 6 Vorträge an 4 Tagen umspannten einen weiten Bogen von geomorphologischen und meteorologischen Problemen arider Gebiete über die Abhängigkeit des Bodenmusters von Relief oder Klima und die bodenbildenden Prozesse in warmen und kalten Wüsten zu den ökologischen Bedingungen und schließlich zu Problemen der Landnuizung in Trockengebieten. Die Tagung bot eine ausgezeichnete Möglichkeit, sich über geomorphologische und klimatische Grundlagen der Bodengenese, -klassifikation und-kartographie sowie über diese selbst zu informieren, während die ökologischen Aspekte einschließlich der Landnutzung weniger behandelt wurden (die Vorträge werden in Sonderheften von CATENA und GEODERMA erscheinen). Die an 3 Tagen gezeigten 23 Poster waren ähnlich ausgerichtet wie die Vorträge und ergänzten diese sehr gut. Da Tagungsräume und Quartiere der Teilnehmer im Kibbutz Kiryat Anavim waren, bot sich über die offiziellen Diskussionszeiten hinaus reichlich Gelegenheit zu Gesprächen innerhalb und außerhalb der Fachgrenzen. Diese intensive interdisziplinäre Kommunikation war ein besonderes, sehr positives Merkmal der Konferenz. Aber auch die Geschichte des Tagungsortes, die Kultur des Gastlandes und die persönlichen Kontakte zwischen Gastgebern und Gästen sowie unter diesen kamen zu ihrem Recht. Auf 2 1 Tag-Exkursionen während und einer 5Tage-Exkursion nach der Tagung wurden semiaride und aride Landschaften und ihre Böden demonstriert, aber auch historische Sehenswürdigkeiten gezeigt. In der Judäischen Wüste wurde in einer Sequenz als Litho-, Luvi-, Xero- und Yermosols der Einfluß von Ausgangsmaterial. Klima und Alter der Landoberflächen studiert und im Jordan-Tal die Bildung von Fluvisols und Solonchaks in Abhängigkeit besonders vom Relief (Grundwasserstand). Auf der Nachexkursion wurden im semiariden Judäischen Hügelland und in der Küstenebene besonders sedimentologische und paläopedologische Probleme behandelt, in der West-Negev und im Negev-Hügelland mit Areno- und Xerosols Verfahren moderner und historischer Landnutzung (Rekonstruktion eines Nabatäer-Hofes bei Ein Avdat) sowie geomorphologische Untersuchungen. Der 3. Tag führte von Sde Boqer durch das landschaftlich sehr schöne Negev-Bergland, wo Yermosols mit Steinpflaster, Wüstenlack und Akkumulation atmogener Soluten sowie Fluvisols mit Takyrbildung studiert wurden, nach Eilat. Nördlich von Eilat wurde eine Chronosequenz von Terrassen des Timna-Tals und ihrer Böden gezeigt (sowie südlich von Eilat eine Pause mit touristischen Attraktionen eingelegt). Am 5. Tag wurden Probleme der Bewässerungswirtschaft im ariden Araba-Tal behandelt sowie eine Fluvisol-Solonchak-Sequenz auf dem Zin-Schwemmkegel bei Sodom demonstriert. Am Fuße der alten Festung Massada dankten die Teilnehmer den gleichermaßen qualifizierten wie engagierten Führern. Dr. J. Dan, Dr. R. Gerson und Dr. D. Yaalon, für eine zwar gelegentlich anstrengende, aber doch höchst interessante Exkursion und nochmals für die erfolgreiche Durchführung dieser überaus informativen Konferenz. E.

Bet Dagan, Israel. 14 Proposed ISSS Working Group AS PRACTICAL PROGRESS AND NEW TARGETS FOR RESEARCH ON ACID SULPHATE SOILS The second international symposium on acid sulphate soils was held in Bangkok from 18th to 24th January 1981. It included a two day field excursion in Thailand and was followed by a tour in Malaysia from 25th to 30th January. The proceedings were charaterized by the enthusiasm of both the 120 participants and the organizers-staff of the Land Development Department of Thailand, the Malaysian Agricultural Research and Development Institute, and the Agricultural University of Wageningen. Netherlands. The high spot for me was a visit to the Carey Island estate of Harrisons and Crossfields, where we saw successful management of acid sulphate soils for oil palm by control of the water table. Since the first symposium, held in Wageningen in 1972. the problems of acid sulphate soils have become widely recognized and there has been an upsurge of research and its practical applications to agriculture, notably in S.E. Asia and West Africa. It was encouraging that most contributions to this symposium were made by scientists from developing countries in S.E. Asia. Equally, it was disappointing that there were no participants from Latin America and only one from Africa. Discussion focussed on land reclamation and development. The continued pressure on land resources will demand continued exploitation of acid sulphate soils and other marginal or difficult land. But it was recognized that the soils are just one element of an integrated system of land, water, crops and people. Land development has an impact on many related facets of the environment and different management strategies will be needed for different physical, economic and social settings. Solid progress has been made in methods of soil survey and analysis to identify acid sulphate soils, and in the amelioration of soil problems by liming, flooding and control of the water table. Attention is now being given to a range of alternative systems of management and to the environmental impact of land development. Understanding of the problems has been furthered by theoretical models and experimentation, but it was recognized that research must move out from the laboratory into the farmers' fields, both to backup basic research and to demonstrate the practical application of new management practices. Acid sulphate soils remain problem soils, and a number of research needs were identified : 1. There is a big gap between basic research, the development of appropriate technology, and the application of this technology to the land. Expert knowledge of the distribution patterns of sulphidic soils, the generation of acid and its transport within the soil and to drainage water, its implications for agriculture, engineering and the environment, and experience in amelioration and reclamation of these soils needs to be published in a brief, easily-understandable and readily-available form. 2. We need a common language and nomenclature for communication among soil scientists, and a common basis for field experimentation and site characterization so that research experience can be transferred to similar areas. 15 3. We are ignorant of plant physiology, especially of root behaviour, under severely acid conditions. There is need for basic research and innovative screening or selection of crop varieties for tolerance to iron and aluminium toxicity and. in the case of rice, for fast growth. 4. The factors that determine the rate of reduction following flooding, and the rate of pH rise to levels beyond those at which aluminium or iron toxicity occurs, should be studied. 5. Models are needed to predict the rate of progress and consequences of reclamation procedures for acid sulphate soils. These models would have to be built up from manageable sub-models fitted together. Examples of such sub-models include the description of voids and their development from season-to-season and year-to-year, and the relationship between water movement in and through the soil to the transport and removal of acid and the rate of reduction. 6. A better understanding is required of the variation in the properties of acid sulphate soils from one region to another: for example, contents of pyrite, iron, manganese, potassium or clay mineralogy, each of which may determine which reclamation or management system will be most effective. 7. Applied research should be directed to improvements in low-cost management, where the constraints are availability of water and fertilizers. In the case of ricebased cropping systems the emphasis should be on minimizing pyrite oxidation and maximizing the removal of acidity by leaching. Research should be carried out within a framework of a baseline survey followed by monitoring crop performance, soil and water composition and hydrology over several consecutive years. Special attention should be given to the problem of safely discarding the acid surface water. 8. Liming is relatively low doses (several tonnes/ha) has given promising results in Thailand, but is not always effective elsewhere. The reasons for this difference should be investigated. Studies on fertilizer application should aim at optimizing the use of phosphate. Sustained and coordinated action is clearly required. It was recommended that an international working group be established with the following tasks: To pool and evaluate information about both innovative and traditional management systems, some of which are not capital intensive and do not require massive application of engineering, soil amendments and fertilizers. To formulate alternative management strategies for acid sulphate soils. To scrutinize technical proposals in soil characterization and classification ; formulate criteria for recognition of acid sulphate problems; and to prepare guidelines for experimental methods and characterization of experimental sites, in the context of their physical and social environment. - To disseminate their findings, not just as bulletins, but to explore contacts with development agencies and land users at various levels. - To convene a third symposium, is four years time, in West Africa. The proceedings of the second symposium are being prepared for publication in 1981 by ILRI, P.O. Box 45,6700 AA, Wageningen, the Netherlands, with Dr H. Dost as the editor. David Dent, Norwich, U.K. 16 IN MEMORIAM Professor Dr. S. Mattson Honorary Member of ISSS (1886 1980) Professor Emeritus Sante Mattson died on 29 May 1980. He was born in 1886 on a farm in Grevie Parish, county of Kristianstad in southern Sweden. In 1905 he emigrated to the United States, where he received his undergraduate education. He did graduate work in colloid chemistry and earned a doctoral degree in Breslau in 1922. After returning to the United States he continued research on the colloidal properties of soil particles. He was early recognized for his pioneering work on the electrophoretic mobility, isoelectric precipitation and amphoteric properties of soil colloids and was appointed docent in 1932 and professor of soil science in 1934 at the Royal Agricultural College of Sweden, Uppsala. Professor Mattson's work in Uppsala during the 1930's was a direct continuation of his research at the New Jersey Agricultural Experiment Station in the United States and included studies of isoelectric weathering and Donnan equilibria in soil formation, the characteristics of podzols, and solubility relationships of soil colloids. During the 1940's and early 1950's, Sante Mattson and collaborators published 6 papers on the pedography of hydrologie podzol series, 11 papers on the acid-base condition in vegetation, litter and humus, and 13 papers on phosphate relationships of soil and plant. Other areas of Mattson's research during this period were geochemistry of raised bogs and effects of excessive liming on leached, acid soils. Professor Mattson made a profound contribution to soil science. His work was characterized by creativity, imagination, careful planning, and inductive reasoning. His fundamental approach to scientific problems may be illustrated by his research on the soil forming process. In his own words: 'In order to understand the soil forming process it is first necessary to know something about the behavior of the soil colloids...' He therefore prepared and studied isoelectric precipitates of iron and aluminum silicates, humâtes, phosphates, and hydroxides. From the results of these studies he then derived the general principles governing the development of soil horizons. Finnally. he checked his inductive conclusions by precise deductive methods. A major reason for Sante Mattson's stimulating influence on soil scientists and the development of soil science was that he applied chemical and physical laws to the study of soils. His studies of the influence of the nature of the exchangeable cation and the composition of the colloid on the ion distribution and the thickness of the electric double layer, the influence of pH, salt concentration and ratio of acidoids to basoids on the electric charge of colloid particles, application of the Donnan membrane equilibrium to the study of ion exchange, the relationships between the structure of the electric double layer and the zeta potential, flocculation and dispersion, and the solubility of phosphate in soils render evidence of an incisive thinking that only very knowledgeable persons can fully appreciate. As a teacher Professor Mattson was highly esteemed and respected. He stimulated his students to think about soils in terms of basic principles and to try to answer the whys of soil behavior. Many soil scientists from abroad have taken the opportunity to work under his guidance and inspiration. 17 Professor Mattson rendered a distinguished service to many professional societies. He was Honorary Member of the International Society of Soil Science and of the Swedish Society of Soil Science, Member of the Royal Swedisch Academy of Agriculture and Forestry, Member of the Royal Society of Science. Uppsala, and Member of the Norwegian Academy of Science and Letters. He served as Consulting Editor of Soil Science for many years and from 1957 as Honorary Consulting Editor. He was conferred the degree of Honorary Doctor of Philosophy at Uppsala University 1952 and Honorary Doctor of Agronomy at the Agricultural University of Norway in 1959. Those who came into contact with Sante Mattson have lost a good friend, inspiring teacher and outstanding scientist. Erik G. Lotse, Uppsala. Sweden Dr. C. R. van der Merwe (1891 1980) Christiaan Rudolp van der Merwe passed away in Pretoria on 27 September. 1980. A graduate of the Universities of Pretoria and Stellenbosch, he was widely known as the author of'Soil Groups and Subgroups of South Africa', his doctoral thesis which was first published in 1941 and revised in 1962. He was a true pioneer, for singlehandedly he opened up wide horizons to a succeeding generation of pedologists in Southern Africa and contributed, to world soil geography, unique information from the southern hemisphere which at the time was largely terra incognita. Dr. van der Merwe was a member of the International Society of Soil Science and served, at various times, as a Council Member of the Society representing Africa, and as scientific correspondent of the Empire and Inter-African Bureaux of Soil. At home, he spent most of his career directing and co-ordinating soil surveys for irrigation and other state development projects, and worked tirelessly to promote a love and respect for the soil. He was a founder-member, in 1953. of what is today the Soil Science Society of Southern Africa, and its first President. His acute mind and his tenacity earned him many awards and honours; his sincerity and modesty earned the respect of all who knew him. J. M. de Villiers. Pretoria. S.A. IS NEWS FROM THE NATIONAL AND REGIONAL SOCIETIES NOUVELLES DES ASSOCIATIONS NATIONALES ET REGIONALES BERICHTE DER NATIONALEN UND REGIONALEN GESELLSCHAFTEN Report on the First Inter-African Soil Science Congress The first Inter-African Soil Science Congress organized by the Organization of African Unity (OAU) Scientific, Technical & Research Commission, and hosted by the Ghana Government was held in Accra and Kumasi from November 10 to 15,1980. The Congress was opened on behalf of the Vice-President of the Republic of Ghana by Ghana's Minister for Foreign Affairs and was attended by the Minister for Agriculture as well as the Minister for Industry, Science and Technology. It was attended by 53 soil scientists from 21 African countries spread throughout Africa as follows: 4 North African countries; 7 West African countries; 4 Central African countries; 3 Eastern African countries; and 3 Southern African countries. Six papers reviewing the development in Africa of six branches of Soil Science (Soil Genesis, Survey and Classification ; Soil Chemistry and Mineralogy ; Soil Fertility ; Soil Physics and Water Management; Soil Microbiology; Soil Conservation and Erosion control) were presented by invited speakers. Also delivered by invited speakers were three papers on training at field level, middle level and University level. The above papers were in addition to the national papers which were presented by each country on the present state of soil science development for agriculture in the respective countries. The need to set up National Soil Survey Services and to strengthen existing ones was stressed. Also recognized was the need for standardization of methologies for soil description, analysis and classification. Furthermore, the training of national soil scientists for research and the establishment of data banks at National and Africa level were considered to deserve a high priority. Research on organic matter recycling to reduce pollution of the environment and to increase soil fertilly without too much use of manufactured fertilizers was also recognized to merit an early attention. Three days were spent on field excursion to examine soil profiles and to tour agricultural institutions and farms near Accra and Kumasi as well as en-route from Accra to Kumasi. Eight soil profiles which included Pellic Vertisol, Vertic Cambisol, Ferric Luvisol, Solodic Planosol. Luvic Arenosol. Eutric Regosol and Dystric Nitosol were examined. The discussion on the classification and management of these soils which were variously used for maize, pineapple and oil palm was at times controversial but stimulating. Twelve recommendations which it is hoped would be considered for implementation by both the OAU and the goverments of Africa were made. These include: the setting up and strengthening of National Soil Research Institutions to cater for various disciplines in soil science; organizing training courses in soil science at sub-regional level ; establishing a soil museum and data bank for Africa ; production of individual national soil maps on the scale of 1:1 million using the FAO/UNESCO legend, to be combined into a soil map of Africa ; and establishment of a programme of exchange of visits between African soil scientists to enhance the exchange of experiences. The full text of the recommendations and the report of the Congress may be obtained from the Director, Inter-African Bureau of Soils, OAU/STRC, B.P. 1352, Bangui. Central African Republic. N. N. Nyandat, Nairobi, Kenya 19 Further to Mr. Nyandat's report it should be mentioned that the Regional Office for Africa of FAO has currently a programme of soil correlation and land evaluation for the continent, through regional sub-committees. In close contact with the Interafrican Bureau of Soils, meetings are being organized alternatively in the Eastern African and the Western African regions. National members and technical observers congregate at such meetings, to report on progress in soil survey and land evaluation in the countries concerned; to present papers on selected topics; and to study soils and soil conditions in the host country (Kumasi 1970, Accra 1972, Nairobi 1974, Dakar 1975, Addis Abeba 1976. (Cotonou 1977), Lusaka 1978, Bathurst 1979, Arusha 1980). The results of most of these meetings are published in FAO's World Soil Resources Reports.

Secretary-General Compte-Rendu du premier Congres Inter-Africain de la Science du Sol Le premier Congrès Inter-Africain de la Science du Sol organisé par la Commission de Recherche Scientifique et Technique de l'Organisation de l'Unité Africaine (OU A)et accueilli par le Gouvernement de Ghana, s'est déroulé à Accra et Kumasi du 10 à 15 novembre 1980. La session d'ouverture était présidée par le Ministre ghanéen des Affaires étrangères au nom du Vice-président de la République du Ghana, en présence du Ministre de l'Agriculture ainsi que du Ministre de l'Industrie, Science et Technologie. Un nombre de 53 pédologues ont assisté au Congrès, provenants de 21 états africains, repartis sur le continent comme suit : 4 pays de l'Afrique du Nord, 7 pays de l'Ouest. 4 pays du Centre, 3 pays de l'Est et 3 pays dus Sud. Six documents recapitulants le développement en Afrique des six spécialités de la science du sol (pédogenèse, cartographie et classification; chimie et minéralogie des sols; fertilité des sols; physique du sol et aménagement d'eau; microbiologie du sol; conservation du sol et la défense contre l'érosion) étaient présentés par des conférenciers invités. Egalement ont été prononcés trois exposés sur la formation au niveau du terrain, au niveau intermédiaire et au niveau universitaire. Les documents-ci étaient supplémentaires aux documents nationaux qui étaient présentés par chaque pays sur l'état actuel du développement de la science du sol pour l'agriculture dans les pays respectifs. La nécessité d'établir des Services Nationaux Pédologiques et de renforcer les services existants était soulignée. On a reconnu aussi la nécessité de standardiser les méthodologies pour la description, l'analyse et la classification des sols. En plus, la formation des pédologues nationaux pour la recherche et l'établissement des banques de données au niveau national et africain étaient jugés de mériter une priorité élevée. Il était reconnu que la recherche sur le recyclage des matières organiques vaut une attention hâtive, afin de diminuer la pollution de l'environnement et d'augmenter la fertilité des sols sans emploi excessif des engrais industriels. Trois jours ont été réservés pour l'excursion de terrain afin d'examiner des profils et de visiter des instituts agronomiques et des fermes dans la proximité d'Accra et de Kumasi ainsi qu'en route d'Accra à Kumasi. Huit profils ont été examinés, y compris Vertisol pellique. Cambisol vertique, Luvisol ferrique. Planosol solodique. Arénosol luvique. Régosol eutrique et Nitosol dystrique. Des discussions parfois controversées mais stimulantes ont été menées sur la classification et l'aménagement de ces sols, qui étaient utilisés de diverses manières pour maïs, ananas et palmier à huile. 2U Douze recommendations ont été faites dans l'espoir qu'elles seront considérées pour exécution par l'OUA et par les gouvernements de l'Afrique. Elles comprennent: l'établissement et le renforcement des Instituts Nationaux de Recherche Pédologiques pour des disciplines différentes du science du sol ; l'organisation des cours de formation en pédologie au niveau sub-régional; l'établissement d'un muséum des sols et une banque de données pour l'Afrique; la production des cartes nationales des sols à l'échelle de 1:1 million basées sur la légende FAO/UNESCO pour l'établissement d'un programme d'échange de visites entre les pédologues africains afin d'améliorer l'échange d'expériences. Le texte intégral des recommendations et le compte-rendu du Congrès peuvent être obtenus du Directeur, Bureau Inter-Africain des Sols, OUA/STRC. B.P. 1352, Bangui, République Centrafricaine. N. N. Nyandat, Nairobi, Kenya En plus du compte-rendu ci-dessus il faudrait mentionner que le Bureau Régional pour l'Afrique de la FAO ait un programme en cours portant sur la corrélation des sols et l'évaluation des terres pour le continent, par sous-comités régionaux. En relation étroite avec le Bureau Inter-Africain des Sols des réunions sont organisées alternativement dans les régions de l'Afrique de l'Ouest et de l'Est. Membres nationaux et observateurs techniques se réunient pour rendre compte du progrès de la pédologie et de l'évaluation des terres dans les pays concernés; pour faire des exposés aux sujets sélectionnés; et pour étudier des sols et des conditions des sols dans le pays d'accueil (Kumasi 1970, Accra 1972. Nairobi 1974. Dakar 1975. Addis Abeba 1976. (Cotonou 1977), Lusaka 1978, Bathurst 1979. Arusha 1980).

He was awarded the degree of Agronomist and Master of Agriculture and Forestry in 1937. and Licenciate and Doctor of Agriculture and Forestry in 1940. He started his scientific career in 1937 as a Chemist at the Institute of Soil Science, Agricultural Research Centre. Here he held the posts of Junior and Senior Agrogeologist and was nominated as the Director and Professor of the Institute in 1947. In 1960 he was nominated to the position of Director General of the Agricultural Research Centre, which he occupied until his retirement in 1973. Jouko Vuorinen's research work was mainly carried out during his time at the Institute of Soil Science as a scientist and as the Director. His principal line of research consisted of the chemical and physical properties of soil and agrogeoiogy. He was particularly interested in the study of factors affecting soil fertility and his name will remain permanently in the history of soil testing in Finland. He was also one of Finland's pioneers in the field of microelement research. Jouko Vuorinen realized the necessity for international scientific cooperation for a small country like Finland at an early stage in his scientific career and especially when responsible for agricultural research as the Director General of the Agricultural Research Centre. During his long career he built up good relations with numerous foreign scientists and scientific institutes in Europe as well as in other continents. He travelled widely in different parts of the world, was an excellent observer and wrote precise travel reports, many of which were published. Jouko Vuorinen took an active part in the work of several international scientific organizations such as NJF (Scandinavian Association of Agricultural Scientists) and ISSS (International Society of Soil Science). His activities in the area of the Food and Agricultural Organization of the United Nations (FAO) deserve special mention. (He was a member of Finland's FAO Committee for nine years and participated in the 16th FAO Conference in 1971 as a member of the Finnish delegation. He served as a member of the Executive Committee of the FAO/European Commission on Agriculture (ECA) for the period 1970-72. and took part in the work of several FAO/ECA subcommittees and working groups. Ten years ago prof. Vuorinen performed the duties of a chairman in the organizing meeting of the Finnish Society of I.S.S.S. The Agricultural Research Centre. Annales Agriculturae Fenniae and his former colleagues edited a jubilee issue (Ann. Agric. Fenn. Vol. 19, No 2 1980) in honour of prof. Jouko Vuorinens 70th birthday. L.

Childs INTERNATIONAL RELATIONS RELATIONS INTERNATIONALES INTERNATIONALE VERBINDUNGEN Report on the UNEP/FAO SECOND EXPERT MEETING ON A WORLD SOILS POLICY February 1981, Rome A 'World Soils Policy' is understood to be a World Policy for the Use of Soils (une politique mondiale en matière de sols et utilisation de terres; eine Weltstrategie für die Nutzung von Böden ; una politica mundial de suelos y uso de la tierra). About 45 scientists*1 from both national and international institutions and organizations met in Rome to defire and elaborate such a policy, and to prepare a plan-ofaction for its implementation. A first, preliminar meeting on the subject was held in March 1980 (see ISSS Bulletin 57). As before, the meeting was organized by UNEP (United Nations Environment Programme. Nairobi), with the cooperation of FAO. Among those invited were several members of the ISSS Executive Committee. Elaboration of the World Soils Policy (WSP) The participants commented, often in writing, on a set of three draft papers, prepared by UNEP consultants Peter Ahn. F. Suarez de Castro and Hubert Kelley. These drafts were 1) Elements of a World Soils Policy, a 37-pages technical background document, 2) Suggestions for elements of a plan-of-action, 3) Executive Summary of a proposed World Soils Policy and plan-of-action. The detailed document on the elements of a World Soils Policy is being re-written for publication, on the basis of the comments received. The concise document on the Policy itself, and the plan-of-action agreed upon at the meeting, have subsequently been submitted for approval to UNEP's Governing Council. Some excerpts of that document follow (some editorial changes may still take place). The Policy was defined as follows: 'In recognition of the fact that soil is a finite resource, and that continuously increasing demands are being placed on this resource to feed, clothe, house and provide energy for a growing world population and to provide worldwide ecological balance, the governments of the nations of the world agree to use their soils on the basis of sound principles of resource management, to enhance soil productivity, to prevent soil erosion and degradation, and to reduce the loss of good farmland to non-farm purposes.' Its objectives are: - to increase and apply scientific knowledge of the soils of the world to their potential for production, and their sound management; - to encourage and assist countries in improving the productivity and management of their soils and in reducing soil degradation; - to encourage the management and conservation of soil, reduce pollution, and improve the quality of water and air. - to develop and promote agricultural production systems that assure the use of the soil on a sustained basis; - to enlarge and improve the world's supply of arable agricultural land through irrigation, flood control, and reclamation; - to slow the loss of productive agricultural and forest land to other purposes; - to monitor changes in soil quantity and quality and in land use; and 25 to bring to the attention of the people of the world, and their political leaders in particular, the extent of world soil degradation and its seriousness; its causes and its remedies. It is addressed to: international and regional organizations, including UNEP. FAO and Unesco. who will share in promoting and supporting the international and regional activities suggested ; national governments and non-governmental organizations, without whose support the recommendations cannot be carried out; individuals who. conscious of their individual and collective responsibilities for safeguarding soil, water and related resources, are willing to lend support to the principles of a World Soils Policy. »«9 »J BhL^fl m •fl " See group photograph.

F. Purnell; Dr. D. Sanders; Dr Go Ban Hong; Mr. R. Sant'anna and Mrs. H. Tonkin. 20 The Plan-of-Action for the World Soils Policy was summarized as follows: a) The appropriate international Organizations should: - Promote a sound use of land and water resources. Continue and intensify efforts to create awareness of the necessity for rational resource use among all sections of the world community, including governments and non-governmental organizations; assist where required to provide training, to mount publicity campaigns, seminars, conferences and the provision of publications. Intensify efforts to promote optimum land use for sustained production on a worldwide basis and interregional and international cooperation in the use and development of land and water resources. - Promote cooperation between governments in adopting sound land use practices, particularly in the international watersheds. Encourage international development financing agencies to pay particular attention to the needs of agricultural development projects which include the conservation and improvement of soil and water resources, the provision of inputs and incentives at the farm level, and establishment of the necessary institutional structures as major components. Assist governments, on request, to establish appropriate legislation, institutions and procedures to enable them to mount, implement and monitor appropriate land use and soil and water management programmes. - Encourage the expansion of bilateral assistance to developing countries in resources management from the developed countries, foundations, and other institutions. - Help countries to improve their capabilities to assess the agricultural potential of their soils, to expand the wise use of fertilizers and to apply improved soil management. Select critical areas of resource degradation for application of experimental pilot programmes of resources improvement. Harmonize the collection and exchange of information on practical applications of soil research among international organizations and institutions, in particular: i promote the adoption of an international reference system of soil classification ii with a view to facilitating transfer of experience and technology; iii develop simple soil capability classifications and land evaluation methods; develop common methodologies for monitoring soil degradation and changes in land use. - As a final objective, incorporate the principles of national land use and the conservation and development of soil and water resources into a comprehensive international resource law. in the form of a World Soil Charter. Hold recommended regional meetings to consider world soil problems and suggest that the General Assembly of the United Nations convene a world conference on soils policy. b) All national Governments should : - Commit themselves to the sound use of land and water resources. Develop a land use policy and the necessary legislative framework to implement it. Increase awareness among all sections of the community of the problems caused by the loss of productive soil and of the need for prompt action. Identify, map and assess the potentials and constraints of soil resources, map current land use, assess the present extent of soil degradation, predict foreseeable hazards and develop methods for their prevention. Adapt soil capability classifications and methods of land evaluation to local conditions. 27 Develop programmes to ensure the availability and wise application of fertilizers and other actions appropriate to the improvement and sustained use of the soil. Establish an adequate legislative and institutional framework for monitoring and supervising soil conservation development and management. Impose obligations on users, with the aim of ensuring the most rational use of land, through the use of tax exemptions, subsidies, credit facilities and other types of financial devices. Train an adequately paid professional cadre of extension workers to assist farmers in managing soil and water resources effectively. Establish and fund programmes, where needed, of reforestation, irrigation, and reclamation of saline, flooded or other land not presently productive. Actively pursue research needed to develop systems of farming that combine adequate production with resource protection and are compatible with socio-economic and cultural conditions. Help develop local institutions to secure the leadership, assistance and cooperation of farmers in applying soil and water improvement and conservation practices. Provide an adequate programme of environmental education in support of resource management activities. In the document also some specific recommendations were made to UNEP, FAO, and Unesco for future action: Strengthen the current effort of the United Nations system to assist the developing countries to set up national institutions for soil inventories and land evaluation. This should include the training of scientists in fields related to soil management and conservation. - Establish a clearing house for the collection and exchange of information on the practical applications of soil research among international organizations and institutions. Support the establishment of the proposed International Board of Soil Resources Management. Support the development of an international reference base for soil classification. Support the preparation of guidelines and methodologies for practical land capability evaluation systems at the national level, on the basis of a global framework for land evaluation. Support the development of methods for land resources monitoring at both global and pilot levels. Review of on-going international activities As in the case of the March 1980 meeting, advantage was taken of this international forum of soil scientists to exchange information on current international programmes on soil- related subjects. Most of the reviews given built upon earlier statements (see Bulletin 57 for their listing). Mentioned for the first time was among others the EEC programme on 'Land Use and Rural Resources' in Western European countries, presented by Dr. Jamagne from France*1. Staff-members of FAO elaborated on some new inter-Agency activities. These are a) The just completed FAO/UNEP's "Soil Degradation Map at scale 1:5,000,000 for North Africa and the Middle East', with an explanatory text, in •' It is the intention of the editor of the ISSS Bulletin to have short articles on individual international programmes printed in successive issues, for general information of members. In the present issue please find descriptions of the mentioned EEC programme, of the "European Cooperative Research Network on Trace Elements*, and of the 'Save-Our-Soils' project of IFEAS. The next issue will contain among others a review of SCOPE'S 'Land Transformation Project.' 28 English, French and Arab (see this Bulletin's Book Review Section); b) the recently started FAO/UNEP programme to develop methodologies for assessment of desertification at different mapping scales;c) the nearly completed FAO/UNFPA study of 'Potential Population Supporting Capacity', concentrating on the African situation ; d) an action programme, including a series of on-going regional workshops by FAO/SIDA, on the application of integrated soil management, soil conservation and recycling of organic wastes in agriculture; e) the on-going consultations by FAO/Unesco/UNEP/lSSS on an 'International Reference Base for Soil Classification' (see this Bulletin). FAO also prepared a detailed policy paper on a strategy for 'Soil and Water Conservation', for consideration by the sixth session (25 March - 3 April 1981) of its standing Committee on Agriculture. It is a well-wrought document and contains several specific project proposals at local and national level. Also a draft 'World Soil Charter' was prepared by FAO. at the recommendation of the 1974 World Food Conference. Although elements of these FAO papers were included in the WSP document, it did not become quite clear whether future FAO-efforts will indeed be harmonized with UNEP's World Soils Policy activities as discussed above, and viceversa. Certainly, a coordinated action is needed, in view of the present scarcity of international funds and the urgency of effective action on soil conservation at local and regional level in many countries! W. G. Sombroek NEW: INTERNATIONAL ORGANIZATION FOR CHEMICAL SCIENCES IN DEVELOPMENT (IOCD) An ambitious Unesco project has just got underway to link chemical scientists throughout the world to programmes benefitting the Third World. The project is the newly created International Organization for Chemical Sciences in Development (IOCD). Its aim is to provide training, research and communications as well as technical services through a network of co-operating institutions. Unesco provides the secretariat for the undertaking. Collaborating in IOCD's programmes is the University of Missouri in the USA which is offering to investigate chemical samples from universities in developing countries that do not have the necessary analytical facilities. Also participating are the University of Ljubljana in Yugoslavia, and the Institute of Organical Natural Products at Tenerife. Spain. From: Unesco Features, No. 760. 29 THE 'SAVE OUR SOILS' PROJECT Introduction Arising from the considerable concern expressed at the U.N. Environment meeting in Stockholm in 1972, a working party was convened in 1976, by U.N.E.P., the International Federation of Institutes of Advanced Study (IFIAS) and the Council of Ministers of the U.S.S.R., to enquire into the causes of soil degradation and the loss of productive soil. The purpose of the Working Party, which was held at Samarkand, was to enquire into what steps should be taken and what area of knowledge should be investigated in order to reduce or control this loss. The Samarkand Working Party identified five causes of the loss of productive land. They are (a) a progressive exhaustion of the plant nutrient sypplying power of the soil, due to leaching of nutrients in drainage waters or to long continued removal of nutrients in plant and animal production; (b) the erosion and loss of topsoil associated with cultivation of sloping land and overgrazing of pastures in semi-arid, sub-humid and humid lands. This was associated with desertification in semi-arid areas, even on flat and gently sloping lands, and with restriction of cultivation by deep gullying in better watered areas; (c) by erosion associated with deforestation, associated with commercial timber cutting, extraction of firewood, forest fires, or shifting cultivation - particularly in the wet tropics; (d) loss of production in irrigated areas due to salinization and water logging: (e) absolute loss of land to agricultural activities because of the extension of urban areas, railways, airfields, etc. The techniques for the control of these degradative processes, except the last, have already been worked out. They include the use of fertilizers to restore nutrients ; the use of contour cultivation, strip cropping, contour banks and grassed waterways to control erosion on sloping lands under cultivation, the use of fertilizers and controlled grazing to maintain a protective vegetative cover in grazing lands; the use of minimum cultivation and surface mulch to protect the soil surface against rain-drop action : the use of agro-forestry techniques to provide wood fuel supply and alternative income or food sources on land too steep for normal cultivation ; and by drainage and control of water table depth in irrigation areas. For all these the principles are known, although they may need to be adapted to the needs of any particular environment. As a result of their considerations, the Working Party set up a steering committee including representatives of FAO, UNEP, Unesco and GKNT., which recommended that IFIAS should develop a project which would investigate the extent to which socio-economic factors were responsible for the failure to apply known technologies for the control of soil degradation in developing countries. The intention was to establish a co-operation with six to eight centres in the warm semi-arid and wet tropical regions. 30 In 1978 the I FI AS Board appointed as Project Director Dr. E. G. Hallsworth, Chairman of the Land Resources Laboratories of CSIRO, Australia, and previously Chief of their Division of Soils. He took up responsibilities in May 1979 (Present address: IFI AS/SOS, Science Policy Research Unit of the University of Sussex, Falmer, Brighton, Sussex BNI-9RF, U.K.) Plan of Action The plan of action envisaged the project being undertaken in two stages. In Phase I, which would take about one year, the Project Director would visit potential centres for co-operative study, and in discussions at each centre would try to identify the various restraints. Funding for this phase was provided mainly by UNEP. Phase II was to include desk studies of the relationships between soil degradation and the biophysical factors of climate, topography and soil, with such social factors as population density, size of holding, etc. superimposed on this. The major feature in Phase II, however, was to be an analytical report on a series of case studies undertaken at each centre in areas where soil degradation had occurred. Towards the conclusion of Phase I, in May 1980 a Working Party was held in Sochi, in the Soviet Union, attended by representatives of most of the centres that had agreed to co-operate, together with several Soviet scientist and a representative from China. This Working Party developed a format for the basic questionnaire to be used in the case studies of Phase II. This would be used to enquire into the extent to which the appropriate remedial measures had been attempted and the success that had attended them. The first restraints to be considered are the biophysical - the soil; its nature and depth; slope of the land surface; nutrient status. - the climate; total rainfall, distribution and reliability; frequency of high intensity storms, etc.; temperature regime; wind pattern. - the biotic factors; natural vegetation, extent and manner of removal; present land use pattern; plant, insect and animal pests of the present crops. The second are socio-economic - agronomic practices water management practices conditions of land tenure excessive fractionation of the family holding total holding is too small to allow the farmers to sacrifice the ground required for contour banks, tanks, etc. population density and age pattern capital available and source of credit type and quantity of power available for cultivation (hand labour, oxen, tractors) inadequate arrangements for the maintenance of the equipment required for the new technology marketing arrangements for the cash crops transport facilities health of the population source of fuel for cooking, etc., and lack of viable alternatives to present practices traditional or religious restraints on what work can be done, or what animals kept the financial or legislative proposals that are associated with the new technology are prejudical to the wealthier members of the village community and so generate hostility .'1 - bad communication between officials and farmers, or between different government departments. These are related to presence and quality of the advisory services, the education level of the cultivators - the technological restraint that the technology proposed may be inappropriate to the soil or to the climatic environment. Part of the work of Phase I was to discover what data was available in the different centres, and in particular to find people in the centres whose existing programme ran close to the ideas of the SOS project. Such people were found at several of the centres. Because of the importance of deforestation in causing accelerated erosion and land degradation in the tropical areas, a second working party was organized to take place at Dehra Dun to look at the socio-economic effects and causes of different forest management practices. Work on Phase II began on September 1st 1980. with later starting dates in some countries, with the close co-operation of three of the international agricultural research centres: the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) at Hyderabad. India, the International Institute for Tropical Agriculture (UTA) at Ibadan, Nigeria, and the International Fertilizer Development Centre (IFDC) at Muscle Shoals , U.S.A., whilst the Centro Internacional de Agricultura Tropical (CIAT) at Cali, Colombia, provides accommodation and help. In all, by the end of 1980 investigations were in progress, or planned to start in the New Year, in twelve countries. These were Bangladesh, Colombia, Jordan, India, Kenya, Nigeria, Mexico, Peru, Philippines, Senegal, Venezuela and Zaire. The West African studies were co-ordinated through UTA, and those in India were undertaken by IFDC and ICRISAT. The Sochi Working Party recommended that an attempt should be made to have a study centre in a country with a planned economy. An agreement for a centre in China is now awaiting formal approval in Beijing. In addition to the country desk studies and the regional case studies, a comparative study is being made ofland tenure, soil conservation, and forestry legislation in each of the co-operating countries. When this study, which is being made by Tyrrell Burgess of the North East London Polytechnic, is completed, it is planned to hold a small workshop to be attended by representatives of each country to discuss this legislation, and the extent to which it is being implemented. It is planned to hold a final working party of co-operators from all the countries concerned at Wageningen, Holland to discuss the findings and to draft the final report. If funds permit, a mid-term working party will also be held. Finance for Phase II has been supplied mainly by the Dutch Government, the Japanese Shipbuilding Research Foundation, and UNEP. Partial funding of the Dehra Dun workshop was provided by NORAD and the Indian Government. E. G. Hallsworth. Brighton, U.K. 32 FOURTH INTERNATIONAL SOIL CLASSIFICATION WORKSHOP HELD IN RWANDA (June 2-12, 1981) The Institut des Scienes Agronomiques de Rwanda (ISAR) and the Ministry of Agriculture of Rwanda (MINAGRI) cohosted the 4th International Soil Classification Workshop organized by the Soil Management Support Services (SMSS) of the Soil Conservation Service of the USDA and the University of Puerto Rico. Funding for the workshop was provided by the U.S. Agency for International Development (AID) and the Algemeen Bestuur voor Ontwikkelings Samenwerking (ABOS. the Belgian Technical Assistance Program). The workshop is the fourth in the series - the first workshop was in Brazil in 1976, the second in Malaysia-Thailand in 1978, and the third in Syria-Lebanon in 1980 and was attended by 60 participants from 25 countries. The theme of the workshop was on the classification and management of soils in tropical mountain areas. The purpose of the workshop was, as in the previous workshops, to test and refine the U.S. Soil Taxonomy for soils in the intertropical areas. Seven international committees (1) are now working to develop criteria and make proposals to refine So/7 Taxonomy for ist better use in the intertropical areas and the workshop was organized to discuss the mandates of four of the committees - the committee on soils with low activity clays (ICOMLAC), the committee on Oxisols (ICOMOX), the committee on soil moisture regimes in the tropics (ICOMMORT), and the committee on volcanic ash soils (ICOMAND). More than 40 technical papers were presented and the subject matter ranged from properties of the Sombric horizon (by Prof. Dr. R. Frankart, Belgium) to the application of geostatics for the evaluation of spatial variation of soil properties (by Prof. Dr. G. Uehara, Hawaii). Discussions on management of these weathered soils was led by Drs. J. M. Spain (CIAT, Columbia) and B. T. Kang (UTA. Nigeria). The participants also received an excellent briefing of Some of the participants in the Rwanda Workshop relax beside a profile pit. Mr. Henri Neel (standing j was the main organizer of the conference and in the front row are from the left. Dr. Leamy (New Zealand. Chairman ICOMAND), Dr. Beinroth (Puerto Rico, Chairman of the Steering Committee) and Dr. Comerma ( Venezuela, Chairman oflCOMERT). 33 the soils of Rwanda through the papers on the geomorphic setting (H. Neel), micromorphology (H. Eswaran), Oxisols (E. Birasa). mineralogy (G. Stoops), soil moisture and temperature regimes (R. Tavernier), Ultisols (R. Marijnissen), and management properties (V. Rutunga). More than 16 pedons. with excellent supporting data, were shown during the field trips. Around Gisenyi, close to the picturesque Lake Kivu, the participants were able to evaluate soils formed on recent ash and cinder deposits. Situated at elevations of 1.500 to 2,500 m the area is suitable for temperate crops like Irish potatoes and strawberries. Dr. Van der Zwaag of the International Potato Centre's field station at Ruhengeri briefed the participants on management of the soils for potatoes. The remaining part of the field trip was devoted to the soils formed on transported and reworked sediments. If the original material had resistent materials like quartz or petroplinthic gravel, the stone-lines in the soils were composed of these materials. Frequently, dislodged saprolitic or textural B material which were rounded during transport, are now present in the soils and act as the stone-line. These rounded bodies are termed pedovites. The highlight of the field tour was the soils with sombric horizon. Although many were convinced that the sombric horizon is a buried epipedon, there was general agreement that it is morphologically important and should be used as a diagnostic horizon. Much of the discussions were focused on the definition of the limit between the Oxisols and the highly weathered members of the Ultisols and Alfisols. There was a concensus of opinion that an oxic horizon at shallow depths was more important to use and management of the soils than a clay increase with depth unless there was less than 40 percent clay in the surface horizons. The latter kind of soils were brought together in a new category in the Alfisols and Ultisols as the kandi taxa. These and other proposals from ICOMLAC and ICOMOX will be further discussed and submitted for testing. The ICOMAND chairman. Dr. M. L. Leamy, led the discussion on the definition of the Order of Andisols and the suborders. There was considerable disagreement to the use of'Trop' at the suborder level and it has been dropped from the key to the suborders. The organizers have indicated that the proceedings will be published by mid-1982 and may be obtained from Dr. H. Eswaran, the Program Leader of SMSS. This workshop, as expressed by Dr. Sombroek, Director of the International Soil Museum during his closing addres, is an example of international cooperation which can serve as a model for similar efforts. The flawless and almost perfect manner in which the workshop was organized is a credit to the organizers. Mr. H. Neel and his Rwandese colleagues must be congratulated for the local arrangements. The technical excellence and overall organizational aspects of the workshop was assured by the untiring work of Dr. F. H. Beinroth of the University of Puerto Rico and Dr. H. Eswaran of SMSS, the Chairman and Secretary of the workshop, respectively. The workshop also provided a forum for the scientists from the less developed countries to express themselves and we take this opportunity to thank USAID and ABOS to make it financially feasible. S.

The present article deals only with the Land Use and Rural Resources part of the Commission's research programme. This Land Use programme was established in 1975 following the Council Decision to set up 4 major agricultural research programmes for the period 1975-1978 (2). Three years of co-ordinated effort pinpointed the major problems associated with land use and rural development within the Community thus ensuring subsequent Council approval for a five-year comprehensive programme on Land Use 1978-1983 (3). This programme, co-ordinated by Dr. P. Ryan, has recently been organized under three expert groups, each with its own chairman. The work programme is structured as follows: Land Use and Rural Resources Programme. (Co-ordinator: P. Ryan) 1. Land Resource Evaluation (Chairman: D. B. S. Fitch/R. H. Watkins) - Soil Map - Forage Map - Methodology projects 2. Land Resource Development and Conservation (Chairman : G. A. Oosterbaan) - Drainage/Reclamation - Soil Degradation 3. Integrated Rural Development (Chairman : L. van der Plas) - Integrated case studies - Multiple job holding/job flexibility - Factors influencing land prices and the impact of land prices on land use. The background to the work of the expert groups on Land Resource Evaluation and Integrated Rural Development is given in the proceedings of two recent seminars sponsored by the Commission of the European Communities, through the coordination of Agricultural Research Division of the Directorate General for Agriculture (4,5). The proceedings ofa third seminar on soil degradation, which forms part of the Land Resource Development and Conservation programme, are in press (6). The drainage and reclamation aspects of the same programme will be the subject of a seminar in 1981. Land Resource Evaluation The soil map of Europe (scale 1: 1.000.000) has, in co-operation with FAO, reached an advanced stage of preparation. The soils information has been up-dated for the nine Member States, as well as Greece, Portugal and Spain. The map and accompanying bulletin will be ready for printing in 1982. The development of a land suitability system for specific crops is considered an important follow up. Presently a methodological approach to the production ofa forage map of Europe is under investigation. The future orientation of the Land Resource Evaluation part of the programme will depend on the outcome of five methodology projects presently in progress across the Dutch/German border and in France, Ireland, Italy and the U.K.. These have already served to draw attention to the contrasting methods of land assessment. It is hoped that an integrated European approach will emerge before this phase of work is completed in 1981. Already workshops have been arranged to make recommendations on a uniform land evaluation methodology and the need for computerized land use data. 35 Land Resource Development and Conservation The Land Resource Development part of the programme concentrated on eight projects on multiple land use. drainage/reclamation and soil degradation. Generally, scientific projects of this nature are of long duration, but it was decided to confine these preliminary projects to three years. The multiple land use aspects of this programme are now part of the Integrated Rural Development programme. New priority proposals on soil degradation and drainage/reclamation will be considered before the end of 1981. Integrated Rural Development The main concentration of effort in this section of the programme pertains to eight integrated case study projects undertaken in disadvantaged areas of the community. These projects, in addition to three projects on multiple job holding/job flexibility, have only recently been approved. The case study projects will investigate the methodology of a multi-disciplinary approach to integrated case study problems, within an administrative area, as well as the following aspects: (a) A survey of current land use and land use potential, in the context of multiple land use. (b) The interrelations between farming, part-time farming, marginal farming, tourism, industries, services and other activities. (c) A survey of institutions/agencies affecting the development of the area, especially those mobilizing and influencing local potential and articulating local needs. (d) Proposals for development strategies including policy evaluation of both EEC measures and national measures. The first phase of this programme wil examine methodology. This will necessitate a mid-term evaluation. In the second phase of the programme the proposed studies will be undertaken according to an agreed methodology. General Programme Co-ordination Besides sharing in the funding of projects the Commission funds meetings, seminars, workshops and exchange visits by European scientists as part of their co-ordination programme. This type of co-ordinated approach is most effective is resolving common problems and opening new avenues for common agricultural policy. It facilitates coordination between programmes and encourages contact with individual scientists and International Organizations engaged in similar type work. A. J. Cole, Rathagan. Ireland.

One of these is the "FAO-European Research Network on Trace Elements'. It was established at a consultation meeting held in Bonn in March 1977. On the basis of a preliminary report by Dr. M. Sillanpää (Finland), the objective of the network was defined to undertake joint research projects on trace elements according to an agreed methodology and division of labour. In order to comply with the structure of other F.A.O.-networks, different subnetworks were formed which concentrate on particular subjects and a coordinator centre of the network was designated. Thus the outline of the cooperative programmes and activities are as follows: 1. Subnetwork A: the estimation of the trace element status of soils and plants by chemical analysis. During the period 1977-1981 comparative chemical analysis were carried out on a number of soil and plant samples. Soils were analysed for: - their total trace element contents - available contents by a proposed reference method of Lakanen and Erviö (0.5 n NH 4 OAc + 0.02 M EDTA pH 4.65) available contents by the method commonly used in the cooperating countries and laboratories - available contents by the method of Soltanpour and Schwab (1 M N H 4 H C 0 3 + 0.05 M DTPA pH 7.6) Trace elements to be determined are divided into three categories, namely: - without real analytical problems: Fe, Mn. Zn, Cu - with average difficulties: Mo, Co. B, Ni, Cr, Cd, F - those presenting severe analytical problems: Pb, Hg, Se, As, Sb, Sn, Br, Ti. The future activities of this subnetwork are oriented towards the following selected topics : - Criteria to evaluate the influences of trace elements on plant growth and crop quality. In this context pot experiments and biotests will be carried out in order to provide additional information on trace element status of the soil and to complement and confirm chemical soil analysis. The proposed pot trials should also enable the calculation, for the different trace elements under study, of 'coefficients of transfer' from soils to plants. - Guidelines to be defined as critical levels of trace elements in the soil as well with regard to deficiencies as to toxicities. 2. Subnetwork B: the influence of sludge and waste products on trace element inputs and environmental effects. The main activities and topics studied may be summarized as follows: - Estimation of real trace element inputs in soils - Availability and differential uptake of trace elements present in the soil as native compounds or artificial enrichment - Acceptable maximum input of trace elements with sludges, effluents and waste products - Analysis of sludge and compost. Future activities consist of evaluating data of field experiments going on in different countries with sludge or town waste compost. In this way the correlations between heavy metal uptake by different plant species and the soil contents are being calculated. 37 3. Subnetwork C: Evaluation of the effect of trace elements in animal and human nutrition This cooperation started with an exchange of information. An initial analytical evaluation of methods for determining trace elements in feedstuffs has been summarized. The trace element contents of the most important bulk feedstuffs produced in different countries, as well as in animal products in relation to the intake with feeds are studied. An inventory of available information on ongoing research in different countries will be made. 4. Subnetwork D : Passage of airborne trace elements to agricultural soils. The participants of this subnetwork will quantify the flow of airborne trace elements to agricultural soils and crops. Two defined aspects are : - Project D ( 'Atmospheric trace element deposition' is mainly aimed at determining European regional differences in the atmospheric precipitation of selected trace elements by a common and reliable method. To achieve this, participating laboratories have been asked to carry out samplings and observations in rural areas. - Project D2 'Atmospheric trace element input to crops', quantifying the concentrations of selected trace elements in plants (primarily grass) and due to atmospheric pollution, in different regions of Europe. The method of isotope dilution is recommended as a convenient tool to distinguish root uptake from aerial contamination. The contact addresses of the different subnetworks are: Subnetwork A: Prof. Dr. A. Cottenie, Faculty of Agricultural Sciences, Coupure Links 533, B-9000 Gent, Belgium (acting also as the coordination centre). Subnetwork B: Prof. Dr. D. Sauerbeck, bundesforschungsanstalt für Landwirtschaft - Bundesallee 50-3300 Braunschweig, Germany. Subnetwork C: Prof. Dr. J. Bokori, University of Veterinary Sciences, H-1400 Budapest, Hungary. Subnetwork D: Dr. Jens Chr. Tjell. Technical University of Denmark - 2800 Lyngby. Denmark. After the initial consultation in Bonn ( 1977), two progress meetings were held, one in Ghent (1979) and one in Dublin (1981). Detailed technical reports on these consultations can be obtained from FAO-Rome or from the coordination centre in Ghent. This centre has also available a limited number of copies of three supporting technical publications entitled: - 'Essential and non-essential trace elements in the system soil-water-plant' by A. Cottenie et al, 1979. - 'Trace elements in animal nutrition', by J. Bokori et al, 1981. - 'Trace elements in agriculture and in the environment', by A. Cottenie (ed) 1981. A total of 57 research institutions, located in 18 European countries are now participating in the Network. These countries are: Australia, Belgium, Czechoslovakia, Denmark, Finland, Federal Republic of Germany, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Portugal. Spain. Sweden, Switzerland and United Kingdom. Scientists from institutions belonging to countries not yet involved in the Network are welcome to attend the consultations. A. Cottenie, Ghent, Belgium 38 INTERNATIONAL TRAINING COURSES/COURS INTERNATIONAUX DE FORMATION/INTERNATIONALE FORTBILDUNGSKURSE Course in Soil and Plant Analysis A six week course in Soil and Plant Analysis will be held in Reading, England during the summer of 1982.

Review of Research on Modern Problems in Geochemistry, Unesco Earth Sciences No. 16, F. R. Siegel, editor. Unesco, Paris, 1979,290 p. The last three decades have seen important changes of emphasis in the earth sciences. During this relatively short span, the new concepts of global tectonic evolution and a much broader understanding of the early phases of crustal evolution during Precambrian times have gained universal acceptance. At the same time, new methods developed for field and laboratory work, and modern data processing have greatly increased the volume and precision of available information. Geochemistry has emerged in the process as a key discipline, progressively increasing its relevance to many other branches of science. For theoretical reasons alone, a modern review of geochemistry would be justified. Moreover, in view of the rapidly rising demand for agricultural products, minerals and energy to satisfy a fast-growing, raw-material-consuming world population, it is appropriate to ascertain the natural resources of the earth which must provide the materials for such a development. We need to know the particular conditions which were responsible for the formation of our natural resources those already exploited and those not yet discovered - within the context of the general evolution of the earth. Geochemistry will also be called upon in the struggle to ensure that an ecological balance is maintained in man's natural environment air, soil and water. Of special interest to soil scientists are the contributions on weathering of rocks and formation of soils ; the role of major and minor elements, in the nutrition of plants, animals and man ; and the excesses and déficiences in rocks and soils as related to plant and animal nutrition.

ISBN 0-85501-490-3. Since the first edition of this book, the use of ion-selective and gas sensing probes has grown steadily and a greater understanding of the mechanism by which sensors operate has been gained. All this progress has been incorporated into the second edition which retains the dual aim : to provide the analyst with the information necessary lo assess the suitability of elecirodes or probes for particular analyses and to assist development of analytical methods of the required accuracy. This book is devoted to the theory, performance and applications of various types of electrode, probe and sensor. Also covered are the experimental behaviour of electrodes and probes, practical procedures, and doit-yourself ways of manufacturing electrodes.

Analog modelling of transient moisture (low in unsaturated soil. G. P. Wind. Agricultural Research Report 894. Pudoc. Wageningen. 1979. 54 p. ISBN 90-220-0713-8 Hydraulic and electronic analog models are developed for the simulation of moisture flow and accumulation in unsaturated soil. The analog models are compared with numerical models and checked with field observations. Application of soil physical knowledge on a soil technological problem by means of steady staje considerations, pseudo-steady calculation, numerical models and analog models are compared. Some examples of application of analog models on drainage requirements are given. From these it appeared that drain spacing is important to avoid water logging, but that drain depth is more important to obtain workable conditions. Price. Dfl. 10.00 plus postage. Orders lo: Pudoc.

ISBN 3-540-90454-9 (in U.S.A. 0-387-90454-9). This publication is volume 35 in Springer's series Ecological Studies. Geochemistry is defined as the study of the role chemical elements play in the synthesis and decomposition of natural materials of all kinds. Landscape geochemistry deals with the study of the environment that occurs at or near the daylight surface of the earth. This book bridges a gap that exists between general geochemistry and the science of the total environment. It docs this in three ways. First, it provides a description of a philosophy that is common to all chemical investigations carried out in the environment. Second, it presents interlocking principles and concepts for the study of the geochemistry of the environment. Third, it describes ways in which the discipline as a totality may be applied by geochemists and other scientists who study the migration of chemical elements and substances within the environment. The author slates in the preface that this book is 'a general, introductory statement of the current status of a discipline for environmental geochemistry, the scope of which should appeal to young scientists who wish to make contributions to a discipline that is in the formative stage; new opportunities for specialization are evident at almost every turn.' Each chapter has a summary and conclusions and mentions some discussion topics. Many ISSS members will find this an interesting and useful publication.

An international conference with this title was held in Bonn. Federal Republic of Germany from 8 12 October 1979. The conference brought together leading scientists from a wide variety of disciplines who are concerned with and have extensive experience in addressing the food production needs of developing countries. Their assignment was to provide the governments of these countries and assistance agencies with advice and recommendations concerning where future investments in tropical agricultural research and development should be placed in order to meet world food needs through the remainder of this century. The conference focused on the natural resource base that sustains agriculture, and state-of-knowledge reports were prepared on soils, water, energy, and biological resources. These reports were distributed to all participants prior to the conference and served as a common starting point for discussions by working groups organized around these same four resources. Utilizing the findings of the working groups, as well as presentations and discussions during plenary sessions, an editorial committee formulated a summary report that presents the conclusions and recommendations of the conference. Reports available as a result of the conference are the summary : Agricultural Production : Research and Development Strategies for the 1980's, as well as the background reports: Soils. Water.

Since many years it is rightly advocated that the preparation of development plans needs a comprehensive and integrated approach. This, however, is easier said than done. Experience has shown that such type of planning is not at all a self-evident exercise. This awareness gave rise at the Agricultural University Wageningen. The Netherlands, to establish a Research Group that was assigned the task : to make an analytical survey of a comprehensive regional planning process, to identify its component activities and their interdependencies, and to produce a framework for the organization and management of the whole, in particular applied to predominantly rural regions. The presently announced book is the result of that study, in which experts of various disciplines participated. The report concentrates on describing how the concerted efTort of regional planning can be realized, indicating the methodology thereof and the procedures to be followed. In the first part of the book are discussed the general principles of integrated and interdisciplinary procedures. The second part contains a voluminous set of annexes, that are meant to serve as instrumental guidelines for those involved in the planning operations proper. These annexes present a model pattern for the activities to be conducted by a multidisciplinary planning team. Price. Dfl. 40.00 including postage if prepaid. Orders to: ILRI. P.O.

ISBN 08258-8, cloth; 08260-X, paperback. This is the first book to give a rigorously quantitative treatment of the processes that occur in sediments soon after deposition. In the opening chapters, the mathematical theory of early diagenesis is developed : a general diagnetic equation is introduced, and this is discussed in terms of each major diagenetic process. Basic rate equations are derived for diffusion, compaction, pore-water flow, burial advection, bioturbation. adsorption, radioactive decay, and especially chemical and biochemical reactions (for example, organicmatter decomposition, dementation. and replacement). The second part of the book draws on examples from the recent literature dealing with continentalmargin, pelagic, and non-marine sediments to illustrate the power of the mathematical models in the interpretation of such deposits. This book should enable the reader to predict the behavior of chemical substances in particular sedimentary environments. Price: cloth $ 35.50 or £ 14.00: paper S 12.00 or £ 5.30.

The last two decades have seen major advances in analytical instrumentation and their subsequent application in developing refined sensitive, specific and accurate techniques for trace metal determination. Consequently, a greater understanding of the roles of the different metals in health and disease states is being acquired. The normal and the toxic are becoming more clearly delineated. The book presents a balanced perspective on the many aspects of this topical subject. The chapters deal individually with thirthy-one metals and metalloids to which toxic properties have been ascribed. Each element's biochemical role, its toxicology, its distribution in the body, its normal concentration in the diet, and the methods available for its analysis are considered in detail. Colorimetry, fluorimetry, chromatography, polarography and spectroscopy methods are described, whilst over 1750 selected references are quoted. The book concludes with an Appendix describing the analytical procedures in the key area of atomic absorption spectrometry which are used in the author's laboratory. The detailed analytical and toxicological information, together with the numerous tables, comparing apparent normal and abnormal concentrations, make this publication a valuable reference source not only for toxicologists and medical practioners. but also for all analysts concerned with the determination of these metals.

The papers deal with the structure and processes of a mire ecosystem under extreme environmental conditions. The mire is situated near Abisko. North Sweden, and represents a type of tundra on permafrost characteristic of the subarctic parts of Fennoscandia. It was therefore chosen in 1969 as one of the sites for the ecological tundra investigations of the International Biological Programme (1964-1974). The research, carried out according to internationally decided guide-lines, aimed at obtaining better knowledge of the ecological base for the productivity of the whole circumpolar tundra relevant to the needs of man. Apart from the papers in the present volume, some individual works have been published and data from the Swedish project have also been used in international synthesis.

ISBN 90-220-0735-9. This book contains 21 papers presented at a workshop entitled "Models for the behaviour of nitrogen in soil and uptake by plant : comparison between different approaches', held at Wageningen. The Netherlands, from 28 January to I February 1980. Crops yields throughout the world are often severely restricted by lack of nitrogen. This results partly from the high cost of increasing nitrogen in soil and partly from the difficulty of forecasting how to adjust rates of nitrogen fertilizer to different crops and soils. A hundred years of field trials have undoubtedly brought considerable progress but serious difficulties remain. They stem from the dependence of such trials on the weather and on the impracticability of trials on more than a few combinations of crop, soil and weather. It is therefore necessary to extrapolate to a wider range of conditions, so that much error is introduced inevitably and inadequate advice is given to farmers. Mathematical models have therefore been developed to simulate the effect of fertilizers on food production and on ecology. Progress in model development is undoubtedly hindered by lack of communication between the many disciplines concerned. Models are often complex, inherently difficult to understand and seldom described in the scientific literature in sufficient detail to be helpful lo other workers. The net result is that there is a range of apparently different models purposing to do the same thing. Some of the differences may result partly from environmental differences, which allow different approximations and partly from different concepts for particular processes. The Foundation ITAL therefore organized a small international meeting of scientists who have modelled different aspects of the nitrogen cycle. This book brings together the results of this work.

Data Handling for Science and Technology. An Overview and Sourcebook. S.A. Rossmassler and D. G. Watson. North-Holland Publishing Company. Amsterdam. 1980. 184 p. ISBN 0-444-86012-6. This book, sponsored by CODATA and UNESCO, is intended to provide an introductory survey of the basic aspects of handling scientific and technical data, and to indicate selected sources from which more details can be obtained. Immediately following the Introduction, there is an examination of how and why data are generated, with a discussion of the differing degrees to which data have an 'absolute' aspect (in the sense that they can be determined independently of any environmental conditions or measurement techniques) and a brief overview of systems for measuring and recording data. A two-part chapter is devoted to data-related aspects of the biosciences and geosciences. There is also a survey of statistical analysis and interpretation of data. The following four chapters examine four important systematic aspects of data handling : presentation in the primary literature, means of finding data in the primary literature, the critical operations of compilation and evaluation of data, and the standards and guidelines which give structure to data handling. A chapter is devoted to a brief overview of how computers are used in laboratory science to handle data. The final chapter offers a cross-cut analysis of the formal and informal mechanisms by which data are disseminated, involving the interactions between suppliers and users of data. The book therefore addresses itself to producers and users of data as well as to information specialists increasingly called upon to provide numerical data to scientific users. It should prove invaluable in scientific libraries and other information centres in both developed and developing countries.

ISBN 0-89118-064-8. This publication contains six papers presented at a symposium held at the ASA annual meeting in Chicago, Illinios, on 7 December 1978. With land being taken out of production and population of human beings on a continuous increase, the problem of world food supplies has become a major concern. Current indicators show that crop yields are holding steady, after several years of steady increase. This publication changes that bleak picture and examines how today's farmers can increase yields and hence, move up the yield curve. Recognizing the immediate need for high yields, the authors discuss detailed methods which can maximize crop production, nutrient needs of plants, biochemical and physiological considerations, climate and water needs, genetics, and impacts of governmental regulations on agricultural production. Research, educators, students and administrators interested in high yields will find this a valuable publication. Price: $ 5.50 plus 75 cents for orders outside the U.S.A. Prepayment required.

Chichester, New York, Brisbane and Toronto, 1980, 312 p. ISBN 0-471-27802-5 Since 1960 substantially new approaches to soil erosion research have been developed, both in the USA and in Europe. The most significant new development is that the geomorphological and hydrological processes of erosion are being re-examined in detail. The basic assumptions of the Universal Soil Loss Equation are being questioned, and workers in separate fields are beginning to make independent contributions to aspects of overland flow, infiltration, soil crusting, and soil removal. This book is an attempt lo bring this work together for the first time in a research level text. The authors who have contributed are all active in soil erosion research, and bring a range of current viewpoints together. Each chapter may be read in isolation, but chapter topics have been designed to provide a sequenlial text which covers the whole of soil erosion. Chapter 1 is an introductory survey of the field, showing some of the important areas for research development. Chapter 2 sets out the Universal Soil Loss Equation and how it may be used and developed further. Chapter 3 reviews established and new methods for measuring soil erosion. Chapters 4, 5, and 6 examine the processes of water erosion in detail, from empirical, theoretical, and modelling viewpoints respectively. Chapter 7 examines wind erosion similarly. Chapter 8 looks at the implications of new research for soil management, and Chapter 9 concludes briefly by looking to the future of erosion research. The book is intended for postgraduate students, research workers, and professional staff involved in soil erosion and conservation. It is thus of direct interest to personnel in geography, environmental science, agriculture, agricultural engineering, hydrology, soil science, ecology, and civil engineering. This well produced book is profusely illustrated with many tables and diagrams. Each chapter has an extensive list of references. Price: i 22.50 Orders to: John Wiley and Sons. Baffins U n e .

This is of particular concern in view of the continued world population growth and the world's increasing appetite for energy and food. The meeting held in Münster in March 1980 (of which the 29 delivered papers arc presented in this volume), dealt with both the effects of energy systems on climate and with the effects of climate on energy use. Some of the important questions addressed at this meeting were: What climatic impacts can be expected from the various energy, economic and population growth policies? What energy strategies are feasible that would cause acceptable climatic impacts? What are the relative contributions of the various forcing functions to climatic change? What are the relative risks, costs and/or benefits of climatic impacts? - What possible countervailing measures could reduce or even avert impacts on climate? Although the conference lectures arc presented, the book is designed to be a comprehensive and integrated resources book on problems interlinking energy and climate rather than a loose collection of individual papers that is typical of conference proceedings. Another meeting sponsored by the German Government will be held in Berlin in December 1980 on climate/food interactions and their implications for world food security. The lectures given at this meeting will be published by Reidel in mid-1981. Price: Dil. 110.000 (cloth); Dfl. 50.00 (paperback). Prices include postage if prepaid. Ordersio.D.

Hayes, editors. John Wiley & Sons. Chichester. New York. Brisbane and Toronto. 1981. 714 p. ISBN 0-471-27693-6. This text is a companion volume to The Chemistry of Soil Constituents by the same editors (published by Wiley, 1978. 482 p.. ISBN 0-471-99619-X; for contents see Bulletin 56. p. 31). Together these volumes provide comprehensive coverage of the complex topic of soil chemistry. An introductory chapter outlines some of the relevant properties of complexes between soil clay and organic matter, discusses the importance of aggregates and of appropriate distributions of pores, refers to some of the essential biological processes in soil, and indicates how these properties and those of the soil solution are relevant to considerations of soil fertility. This is followed by detailed treatments of the physical and physico-chemical processes of mass flow and diffusion, precipitation, and ion and ligand exchange ; and the adsorption by soil components of both small organic molecules (such as pesticides) and larger natural and synthetic polymer species. Processes which emphasize the importance of micro-organisms and of microbial transformation products are then discussed in three chapters which deal with oxidation and reduction, the complexation and translocation of metals within the soil profile, and with the transformation of organic debris in the soil. The last three chapters discuss the fate in the soil of fertilizers and o potential pollutants, such as heavy metals from applications of sludges, fertilizers, and pesticides. The volumes are primarily written for soil and agricultural scientists, but will interest also researchers in environmental science, pollutant chemists, microbiology, and a range of other disciplines associated with soil behaviour and function. The book, like its companion volume, is clearly written and well produced with many illustrations. Extensive reference lists are given with each chapter.

J. M. Lynch. J. Melting. P. R. Rutter and B. Vincent, editors. Ellis Horwood Publ., Chicester. 1980. 559p. ISBN 0-85312-186-9. This definitive and multi-disciplinary work describes the current state and future prospects of the whole area of research into microbial adhesion, ft is up-to-date, complete in its coverage, and detailed in its information of this rapidly expanding field; and docs not forbear to offer critical discussion of previous approaches. The editors offer a balanced and selective range of experience, which includes both the theoretical aspects of small particle adhesion to surfaces, and the practical problems associated with the adhesion of microorganisms to plant and animal tissue, and to surfaces of industrial importance. The introductory chapters arc designed to overcome any differences in approach between physical scientists and biologists, whilst among the many important ensuing chapters there is description of detailed methods of quantifying bacterial adhesion, and of current research activities in a wide range of topics. For the soil scientist are of particular importance chapters on the surface interactions between clayminerals and microbes, the microbial adhesion to soil surfaces, the role of natural and synthetic polymers in stabilizing soil aggregates, and the flocculation of Rhizobium from soil colloids. The book is published for the Society of Chiemical Industry. London and appears only a few months after the meeting where the papers and posters were presented.

Until now work on soil genesis has mostly been carried out on solid phases of soils and parent materials. Little attention was paid to the weathering agent, the liquid phase, with its solutes. The present study, a thesis of the University of Amsterdam, deals mainly with the water-rock interactions in (very) low-grade mctamorphic shales and the resultant soils in a small, completely forested catchment in the Luxembourg Ardennes.

Brookfield, editor. MAB Technical Notes 13. Unesco. Paris. 1980. 228 p. ISBN 92-3-101821-3. This Technical Note presents a synthesis of the findings of a Unesco/United Nations Fund for Population Activities (UNFPA) pilot project on the interrelations between populations, environment and natural resources development in the eastern islands of Fiji. It constitutes the response of a group of social and natural scientists to Ihe empirical problems of population and development presented by a particular region, a particular set of natural environments and a particular set of socio-economic conditions. Though based on a concrete situation, most papers seek to go beyond empiricism into theory, and draw on data and literature from outside Fiji. The first article describes the project, and the means by which integration was achieved. Subsequent articles discuss three specific aspects on which the project was able to make a useful contribution to knowledge and its application: ihe impact of man's activity on island resources: the carrying capacity question: the vulnerability of small island populations and their resources. Two larger aspects the theoretical framework of the project, and the question of designing guidelines for resource use and population policy in small islands - are the subject of substantive papers. It is hoped that the methods and approaches to problem-solving described in the Technical Note will be of interest to those dealing with population-environment problems in rural settings worldwide. It is also hoped that the experience gained in the Fiji project will help in the design of new research projects in more complex situations in other ecological regions of the world.

Assessment of Erosion. M. de Boodt and D. Gabriels, editors. John Wiley & Sons. Chichester. New York. Brisbane. Toronto. 1980. 563p. ISBN 0-471-27899-8. The Workshop on Assessment of Erosion in America and Europe, on which this volume is based, was a follow-up to two previous meetings held at FAO Headquarters in Rome. The meeting was held in Ghent. Belgium, from 27 February to 3 March 1978. As a result of the Rome meetings a committee was formed to examine the possibilities for developing methods of universal applicability for assessing degrees of soil erosion and for measuring quantitatively its effect on soil productivity, the ultimate objective being the production of a world map. It was decided to organize a workshop to discuss methods for assessing erosion with members drawn from the USA and those European countries with specialists in the field of soil degradation. The papers presented at the workshop were not meant primarily to add to the existing collection of erosion studies but to provide syntheses of the different approaches being developed in the institutions where there was the most experience. The conference was meant to deal specifically with erosion in the industrialized world but ended up with erosion characterization on a world scale. The first papers deal with the evaluation of erosion risks and the mapping of eroded areas in different countries, and they provide a basis for the subsequent papers. Despite the growing awareness of the hazards of continuing soil degradation to mankind the situation is worse than 50 years ago. World population has more than doubled, but apart from a few countries, erosion has proceeded with relatively little attempt to check it. It is hoped that the papers of this workshop will help to draw attention to the dangers facing mankind in allowing soil degradation to continue on its present scale, by stimulating international cooperation in assessing and mapping the degree of degradation and developing methods for overcoming and where possible preventing it. The publication has many tables, figures and maps. It will be of great interest to soil scientists, agricultural scientists and botanists.

New York and London. 1980. 385 p. ISBN 0-12348580-0. This book is a companion volume to Fundamentals of Soils Physics. It applies the basic principles and illustrates how they can be used systematically to define and eventually control - existing phenomena. The first section of the book provides comprehensive treatment of the field water cycle and its management. Topics covered are: the sequential processes of infiltration and runoff; redistribution and storage of soil moisture; groundwater drainage; evaporation from bare soil and soil salinization; uptake of water by plants and transpiration as determined by climate, soil properties, and rooting habit; field water balance and energy balance; crop water requirements and water use efficiency; tillage mechanics and soil structure management. The second section extends these principles further and introduces the reader to the contributions of several leading authorities on topics of vital contemporary interest. The topics discussed include: crop canopy effects on évapotranspiration; freezing phenomena in soils; similitude and scaling; spatial heterogeneity of soil physical properties; and the movement of solutes during infiltration. This publication will serve as an undergraduate text for students in the environmental, engineering, and agronomic science. It will also serve as a definitive reference source for professionals in soil physics and the related fields of terrestrial ecology, hydrology, agronomy, forestry, and civil engineering.

The limits of food production are set by soil and climatic conditions and the use and management imposed on the land. Any 'mining' of land beyond these limits will, in the long run. only result in degradation and lowered productivity. Accordingly, there arc critical levels of populations that can be supported from any given area. FAO and U.N. Fund for Population Activities have initiated the present project todetermine the upper limits of population-supporting capacities of lands. A further objective is to compare these estimates with data on present and projected populations and so identify critical areas where land resources are insufficient to support existing and/or future populations and where action is urgently required to rectify this situation. Land resource aspects of the study are dealt with through delineation of agro-ecological zones wherein soil and climatic conditions, matched to crop productivity, are quantified. Use/management aspects are considered through estimation of the various potentials of the zones for the production of 19 crops under three levels of inputs with various conservation, calorie/protein and crop mix alternatives. Present and projected population data is then related to the potential of the inventoried agro-ecological zones. This project is a follow-up of the Agro-ecological Zone Project (see Bulletin 57 p. 46). The activities of the project are guided by consultations of experts. The Project Coordinator is G.M.

ISBN 0-477-06668-2. 'Soils with variable charge' of the temperate regions and some areas of the sub-tropics, are among the most productive soils of these regions. They are not naturally fertile, and their high productivity has been achieved only after severe limitations to plant and animal production have been overcome. Within the tropical regions, and remaining areas in the sub-tropics, much more work remains to be done before these soils are producing near their potential. This is an appropriate time to review existing knowledge of the properties of these soils, their problems and how they may be overcome by suitable management under various land uses. With this in mind, the New Zealand Society of Soil Science offered to host a meeting of Commissions IV, V, VI and VII of the ISSS which would allow soil scientists of several disciplines to discuss these soils as a single subject. The organization of this meeting also coincided with the 50th Anniversary of the New Zealand Soil Bureau. The present book provides an up-to-date comprehensive review of knowledge on soils with variable charge. As such, the book stands independent of the Conference proceedings, it contains papers on macroand micro-morphology (4 papers), sand, silt and clay mineralogy (4). chemistry (4). physics and mechanics (4), biology (2), genesis and classification (3).

Services Scientifiques Centraux de l'O.R.S.T.O.M.. Bondy, 1979, 301 p. Il s'agit d'une première approximation d'un nouveau système international de classification des sols préparé par un groupe de travail de pédologues de l'ORSTOM. Dans le premier chapitre, une description brève mais très claire et systématique est donnée sur les principes de pédogénèse, les différentes catégories de classifications dites 'objectives', c'est à dire fondées sur des caractères objectifs du sol, la recherche d'un nouveau système, l'objet qui doit être classifié et les méthodes utilisées pour classifier les sols. Ensuite, on trouve une description précise des horizons diagnostiques et des autres éléments de la classification. Chaque fois que cela est possible, ils sont empruntés à la 'Soil Taxonomy' ou à la légende FAO/Unesco. mais avec modifications, qui pour certains aspects résultent des traveaux de divers comités internationaux qui travaillent à proposer des améliorations de la 'Soil Taxonomy'. La plupart des données diagnostiques ont reçu de nouveaux noms, pour éviter toute confusion. Les éléments et principes de la nouvelle classification proposée sont ensuite examinés. Au plus haut niveau figurent les constituants du sol, au second la morphologie, la combinaison des deux permettant la définition du sol; au troisième apparaissent les caractéristiques physiques et chimiques, tandis qu'au quatrième sont proposées des données relatives aux utilisations possibles du sol. Pour terminer les quinze unités les plus élevées et leurs subdivisions possibles sont décrites. L'ouvrage s'achève par une comparaison entre la classification proposée et d'autres systèmes existants, 51 pédons sont données comme exemples avec les méthodes analytiques et un index des termes utilisés. Cette première approximation qui est destinée à être modifiée et corrigée est rédigée en français et n'est pas en vente. Un petit nombre d'exemplaires peuvent être obtenus sans frais auprès des auteurs, qui se proposent de faire paraître prochainement une version améliorée mais abrégée en anglais, avec l'aide du Muséum International des Sols (ISM).

This is a first approximation to a new international system of soil classification, prepared by a working group of ORSTOM. In the first chapters a brief but very clear and systematic description is given on the principles of pedogenesis, the various existing 'objective' classification systems, the search for a new objective system, the object that is to be classified, and the methods used to classify soils. Then a precise descripion is given of the diagnostic horizons and other classification elements. As much as possible these are taken from the US 'Soil Taxonomy' and the FAO/Unesco legend, but with certain modifications that for a part have emerged from a consensus reached in the various international committees engaged in recommending improvements of'Soil Taxonomy'. For all diagnostics, however, new names have been coined, to avoid any possible confusion. The principles and elements of the proposed new classification are then outlined, applying systematically at the highest level the soil constituents, at the second level the soil morphology, at the third level the physical and chemical characteristics, and at the lowest level the data relative to the possible use of the soil. Finally, the fifteen highest-level units and their possible subdivisions are described. The book ends with a comparison of the proposed system with other soil classification systems, 51 example pedons. the analytical methods, and a glossary of the terms used. This first approximation, which is apt to be modified and corrected, is in the French language only, and not for sale. A limited number of copies can be obtained free of charge from the publishers. It is the intention of the OSTOM Working Group to publish soon an English language improved and shortened version, in cooperation with the International Soil Museum ISM.

After a general introduction the main physiographic regions are discussed. These chapters contain data on the landscape, geology, hydrology, vegetation and land use and the description and analytical data of representative profiles. All soils are correlated with Soil Taxonomy and FAO/Unesco Soil Map of the World terminology. The book has many cross sections and some small maps. Each chapter has a list of references for further reading. The price is low. Price. US $ 1 1 . - . Orders lo: Division of Scientific Publications. The Volcani Centre. Bet Dagan. Israel.

Erosion and Sediment Transport in Pacific Rim Steeplands. Proceedings of the Christchurch Symposium, January 1981. International Association of Hydrological Sciences, 1981, 654 p. IAHS Publication No 132. The knowledge of erosion and stream sediment processes is dominated by studies from rolling lands and sand-bed channels in relatively mature landscapes and it is a common experience of those working in mountain lands to find the principles and research findings from these studies applied to steepland management. Steeplands have different and relatively poorly understood problems associated with their stability and use and the Symposium was called to address these issues. The steep and mountain lands rimming the Pacific plate were chosen for particular emphasis as these are geologically, tectonically and climatically different from many continental mountain ranges. The Symposium was held in Christchurch. 25-31 January 1981. The themes were: methods for assessing slope erosion and nonchannel sediment sources in upland regions, stream channel dynamics and morphology, human impact on erosion and sediment yield in steeplands, and the impact and management of steeplands erosion. In all 38 papers were presented. Price: S 45.00 or FF 210. Orders to: Treasurer Int. Ass. of Hydrological Sciences, 2000 Florida Ave NW, Washington, DC 20009.

ISBN 90-6191-081-1 This book contains the complete and updated proceedings of an advanced seminar held at the Joint Research Centre of the Commission of the European Communities in the framework of the Ispra Courses in Ispra. Italy, from 21 November - 2 December 1977. The papers are on agriculture, hydrology, forestry, land use. environmental monitoring and meteorology and deal mostly with Europe and North America. The use of activities in several remote sensing techniques are discussed : the most traditional photointerpretation of aerospace photography, automatic photointerpretation, together with digital processing of multispectral scanner and modern microwave sensors data (radar, passive microwave radiometer). The 30 papers, originally presented in 1977. were updated and re-written, reflecting the rapid progress in this field. Of the many international gatherings in the field of remote sensing, the Ispra Seminar is one of the very few which has limited itself strictly to agricultural and hydrological applications.

Univ., Wageningen, 1980, 100 p. This mimeographed manual is a major revision of the 1971 edition. New analytical procedures, the development of specific methods for the analysis of acid sulphate soils and the extension of the analytical programme of the Department with water analysis made this revision necessary. Most of the elemental analysis described in the former edition are now done by X-ray fluorescence spectrometry (XRFS) and have been omitted from the present edition. Besides the chemical analyses, several instrumental techniques as ionchromatography (Dionex) and (total) carbon analysis (TOC analyzer), were introduced in the analytical programme. It was outside the scope of the manual to describe these specific techniques in detail; summaries and main points are give as the specific outlines of these techniques are attributed lo the two instruments.

This second edition of the general soil map of Ireland at a scale of 1: 575.000 is a great improvement on the first edition of 1969. It includes much new information both in terms of different soil types and more precise distribution patterns. The bulletin begins with chapters on soil formation, the soil survey method and the soil classification system used in Ireland. The soil map legend is based on five major physiographic regions in which 44 soil associations of 10 Great Soil Groups are recognized. The principal soil and the associated soils are given for each association, together with an estimate of their extent. The description of the major soils of the country is followed by an interesting chapter on their limitations as well as their potential for different uses. Information on the soil distribution in Northern Ireland is also included in this map. In conjunction with 'The Peatlands of Ireland' (bulletin and map at the same scale) by R. F. Hammond (An Foras Talûntais. 1979) this is a valuable description of the mineral and organic soils of Ireland.

Agricultural Experiment Station. Purdue University. West Lafayette. Indiana. 1980. 75 p. In delineating differences between soils and in describing the characteristics of a soil profile, colour is one of the most obvious and useful attributes for documenting these differences. For more than 50 years soil scientists have worked to refine and make more quantitative the descriptions of soil colour. Since soil colour is related to numerous other soil properties, it is important that soil colour descriptions be as precise as possible. Recent developments in field and laboratory have reduced much of the subjectivity involved in determining soil colour. New instrumentation also provides the opportunity to obtain precise quantitative reflectance measurements not only in the visible portion (colour) of the electromagnetic spectrum but also in the near and middle infrared regions, x However, in the near and middle infrared there are great differences in both the shapes of the curves and the intensity of reflectance. The purpose of this atlas is to present for the first time a compendium of laboratory-measured soil parameters and soil site characteristics together with reflectance measurements of soils. Only those soil parameters and site characteristics known to influence soil reflectance properties are included, with the recognition that even more detailed soil mineralogical and organic constituent investigations are needed to understand soil refiectance differences. The 251 soils selected represent a wide range of soil-forming conditions characteristic of soils in the United States and Brazil. Prize: US $ 2.00 including postage; prepayment required.

Academic Press, London and New York, 1980, 349 p. ISBN 0-12-323840-4. Herbicides are essential to modern agriculture as it is currently practised and whatever agricultural changes take place in the future the need for them will continue for many years to come. This book, written by members of the Herbicide-Soil Working group of the European Weed Research Society is a critical evaluation of the present knowledge about the behaviour of herbicides in the soil. It is hoped that bringing this information together in one volume will contribute to agricultural practice, academic sciences and legislation. The book contains 10 papers with extensive lists of references and a summary, which is also translated in French and German. The book begins with the physical aspects, such as adsorption and mobility of herbicides in the soil, then goes on to discuss uptake by plants and weed control performance. Subsequent sections deal with decomposition . persistence and finally the effects on soil biology. There is particular emphasis throughout on the limitations of experimental techniques and the ways in which results are interpreted. These factors are examined from the academic, agronomic and legislative viewpoints. This book not only provides an evaluation of the current understanding of the interaction of herbicides with the soil, but it also indicates areas of uncertainty thus providing the basis for establishing future research priorities. It will therefore be useful to scientists and administrators, whether in research institutes, industry or government.

Alexander, editor. Plenum Publ. Corp., New York, 1980. 247 p. ISBN 0-306-40493-1. This review series deals with the ecology of microorganisms in natural and man-made ecosystems. The series focuses on all major microbial types in a diverse group of ecosystems. It examines bacteria, fungi, algae, protozoa, and viruses in such environments as freshwater, ocean, soil, and other ecosystems in which microoroganisms arc prominent. Articles cover both basic and applied problems of microbial ecology and environmental microbiology and consider problems of biogeochemical cycles, pollution, and chemical changes brought about by microbial communities in many habitats and circumstances. The fourth volume opens with an examination of the ecology of protozoa, constraints on their populations, and their role in nutrient cycling and energy flow. This is followed by a detailed outline of recent information on a unique micro-environment, the surface microlayer of aquatic ecosystems. Next, the volume offers an incisive review on the genus Rhizobium, a group of bacteria whose importance has grown as the cost of fuel for production of nitrogen fertilizers and ultimately for protein production has increased. Consideration is then given to two terrestrial ecosystems: flooded soils that are common in much of Asia for rice production; and Histosols, a related ecosystem that is dominated by organic rather than inorganicmaterials. It closes with a thorough evaluation of immunofluorescence as a technique for the study of the ecology of microorganisms. Also Volumes I, 2, and 3. published by Plenum in 1977, 1978, and 1979 respectively contain papers on microorganisms and the soil environment. Price: $ 32.50.

New York and London. 1979. 416 p. ISBN 0-12-223650-5. Here is a comprehensive treatment of the role of pore structure in the interpretation of experimental data and how pore structure affects model calculations. This volume shows the benefits to be gained from studying phenomena in porous media in terms of three factors. These are transport phenomena, interfacial effects, and pore structure. The book provides examples of these concepts in application. One of the major tenets of this book is the inseparability of pore structure from convective. diffusive, and interfacial effects within pores. Following the introductory chapter, the three foundations of the physical phenomena associated with pore space in porous media are discussed. These are capillarity, pore structure, and single phase flow and diffusion. One of the book's features is its numerous cross-references. The building blocks set out in the opening chapters are referred to throughout the book. Thus, it makes an excellent self-teaching tool and reference source. Other topics discussed in detail in this volume include: simultaneous flow of immiscible fluids and immiscible displacement. - wettability and capillary vs. viscous forces, and - miscible displacement and hydrodynamic dispersion.

NASA Conference Publication 2973, 1978, 218 p. The soil moisture workshop was held at the USDA National Agricultural Library, Beltsville. Maryland, from 17-19 January 1978. The objectives were to evaluate the state of the art of remote sensing of soil moisture; examine the needs of potential users; and make recommendations concerning the future of soil moisture research and development. To accomplish these objectives, small working groups were organized in advance of the workshop to prepare position papers. These as well as the keynote addresses and the proceedings of summary and recommendation sessions are contained in the present publication, it was concluded that significant progress has been made in the development of remote sensing techniques for estimating soil moisture. Some useful applications for soil moisture information had been demonstrated to substantiate a research-oriented program for the development of an operational system for the remote sensing of soil moisture. Although mainly dealing with conditions in the U.S.A., the publication is also of interest for soil scientist in other countries.

Reidel Publ. Comp., 1980. 477 p. ISBN 90-277-1158-5. This publication contains the proceedings of a meeting held at the University of Illinois, Urbana from 23 July - 4 August 1979, organized within the framework of the NATO Advanced Study Institutes. During the past few years there has been a marked increase in the use of advanced chemical methods in studies of soil and clay mineral systems, but only a relatively small number of soil and clay scientists have become intimately associated and acquainted with these new techniques. The number of scientific publications using chemical methods to study soils and clays is increasing at a rapid rate, and the time is right to collect a detailed discussion of all of these methods. This was the objective of the meeting. The present publication, volume 63 of the NATO Advanced Study Institutes Series C - Mathematical and Physical Sciences, summarizes the theory and most current applications of six different spectroscopic methods to soil and/or clay mineral systems. The instrumental methods examined are Mössbauer, neutron scattering. X-ray photoelectron (XPS. ESCA). nuclear magnetic resonance (NMR), electron spin resonance (ESR, EPR), and photoacoustic spectroscopy (PAS). The book is certainly much more than just an introduction and it is hoped that the ability of earth scientists to take advantage of a greater variety of research instruments for solving difficult problems will be increased. The book is well produced, cloth bound, and has many tables and figures. For a list of other books in Series C - Mathematical and Physical Sciences, please apply to the publishers.

This meeting brought together people in Australia who were actively working on, or interested in. techniques associated with information systems for soil and related data. Their experiences had been mainly with the use of computers to carry out existing procedures more efficiently than was possible by manual handling. Since that first meeting, there have been a number of development in the administrative and technological fields associated with information systems for soils and other land resource data. With a time lapse of nearly four years since the last meeting, the Soil Conservation Service of New Sout Wales and CSIRO considered it appropriate that another meeting be held in Australia and consequently this second workshop was jointly organized by them, once again under the auspices of ISSS. It was held in Canberra, Australia, from 19-21 February 1980. The wider use of information systems has meant that there is a need for more thought to be given to the type of data collected, the structure of data bases, and the uses and potential users of the systems. It is pleasing to note that all these points are discussed in papers presented to this workshop. Price: Dfl. 25.00 Orders lo: Pudoc, P.O. Box 4, 6700 AA Wageningen, the Netherlands.

This is the first scientific journal to focus on the development of biological husbandry as a viable form of agriculture. During the past 40 years agriculture and horticulture in the developed countries have become more intensive, mechanised and energy-consuming. Although these developments have resulted in very large increases in productivity they have been shown in some instances to have been accompanied by detrimental side-effects of an environmental and social nature and by an excessive use of world resources. More recently, since the energy crisis, this system of agriculture has become subject lo the constraints of rapidly-increasing energy prices. Problems associated with modern, conventional agriculture may become intensified when they system is applied to the developing countries indeed this type of agriculture is frequently not applicable to the economic and social conditions to be found in these countries. Alternative systems, based upon biological principles, have been devised with the intention of minimising these problems. Such systems of biological agriculture and horticulture, otherwise known by the overall term biological husbandry, attempt to provide a balanced environment in which the maintenance of soil fertility and the control of pests and diseases are achieved by the enhancement of natural processes and cycles, with only moderate inputs of energy and resources - but without any significant loss of productivity. The areas covered by the journal are: soil fertility and management, biological control methods, energy utilization studies, agricultural systems, development of appropriate technologies, and biological agriculture and horticulture.

Space technology has now progressed from the initial phase of exploration, and this progression has led to four major areas of utilization which have been developed to varying degrees : telecommunications ; observing and monitoring Earth's resources and environment; using the space environment to further scientific research into natural and life science phenomena and to look for new products and techniques: and the fulfilment of mankind's energy needs. This progress, however, has created significant and steadily increasing information gaps between developers and users of space technology - systems designers and specialists - policy makers suppliers of technology. This quarterly will provide the information bridge between these groups. Emphasis will be on practical applications, systems, performance and factual information. Surveys, trend analyses, strength and weakness assessments, cost-benefit analyses, legal aspects and social implications will also be covered.

Soil Survey and Land Evaluation, A Young and D. Dent. Editors. A new international journal, 3 issues per year. Geo Books. Norwich. This new journal is designed to act as a forum for communication between those engaged in soil survey, in land evaluation, and in the application of the results of these activities to land use planning and management. The journal serves as a link between individuals engaged in soil and land evaluation surveys and between the different kinds of organization concerned : national soil surveys, international organizations, consultant firms and universities. A further function stems from the nature of the work itself. There is a spectrum of activities, commencing with soil mapping, continuing through soil survey interpretation and land evaluation, and ending with the many ways in which the results of surveys are put into practice: farm advisory services, land use planning, land development projects, engineering works, land management in the urban fringe zone and many other ways. There is a real need for those concerned with one part of this spectrum to communicate with others, on the one hand, so that soil surveys can supply users with the information they need, and on the other, so that the results of surveys are received with understanding and put to good use. The major fields of interest of the journal are thus: soil survey, its methods and content, soil survey interpretation and land evaluation, and the application of the results of soil surveys and land evaluation studies to planning and land management. The journal includes substantive articles, technical notes, reports on survey developments in different countries, reviews of books, survey maps and memoirs, and ongoing discussion of topics raised. Volume I appears in 1981. Subscription price: £ 3.50 or $ 8.50(1981) including mailing charges.

Status of Subcommissions and Working Groups 1.1 Subcommissions (a) A subcommission is defined as covering a subject that goes across the subjects of several Commissions, and is of a semi-permanent nature. The members of a Subcommission (c.q. those attending a Subcommission meeting) elect their own Chairman and the other Officers, in a way indentical to that of the Commissions (see Rule H.9). Even though more members may participate in an official Inter-Congress Meeting on the subject than in the General Congress, this election of Officers should take place at the latter event. (b) The Chairmen of the Subcommissions are not members of the Executive Committee; they are to be represented at EC and Coucil meetings by a Commission Chairman of their choice, to he approved by the Coucil. Proliferation of Subcommissions should be avoided. 1.2. Working Groups (c) Working Groups ( theformer'Committees' ) are definedas dealing with ad-hoc problems usually within the sphere of interest of one Commission. They therefore should have a deadline of existence and their activities should he wound upl terminated at some stage. Their Chairmen arc nominated by the Chairman of the Commission(s) concerned (Rule H.l 1). and should be approved by the Coucil during the General Congress. (d) At each General Congress the mandate of a Working Group is to be reviewed, leading to either a continuation or termination of its activities. (e) The Secretary-General should remind the respective Commission Chairman well before the General Congress that he investigates on the useful life-span of his Working Groups, and that the invites each to submit either a terminal report, or a state-of-the-art report with a suggested programme for the postCongress period, including an expected date of completation of their activities. Unlike the situation with the Subcommissions, no provisions are made for the appointment of ViceChairmcn or Secretaries for the Working Groups from the host country of the next Congress. One of the reasons for this is that a Working Group Chairman may want to have a Secretary if he wants one at all to reside nearby, for close contact on solving ad-hoc problems, and for help in servicing the Working Group. Because the Council will have to approve the creation of a new Working Group (Rule H.ll). (0 there can be no formal establishment of a new Working-Group in-between Congresses. If a group of members wants to start tackling an ad-hoc problem well before the next Congress and the activities are being prepared and executed with substantial vigour, then the Secretary-General should (g) be duly informed and a provisional steering committee may be formed, provided the Executive Committee approves through correspondence with the SG. Note by the SG : Proposed by-laws (0 and (g) will become superfluous, if the proposal for a change-ofrule. as put up for voting in Bulletin 58, is carried. (h) In a similar way, not officially Council-approved Inter-Congress Activities (e.g. symposia on a specific problem) can become 'morally supported by the ISSS, upon approval by the Executive Committee through correspondence with the SG. It is stipulated that in such cases the meeting should have an international character, that the announcements be made well in time, that the E.C. members are invited to participate, and that they be represented on the steering or organizing committee. Note: Official Inter-Congress Acitivities are. likewise as the Congress, open to ISSS members only, unless they are joint undertakings with non-ISSS organizations. In either case the organizing committee should require that attending soil scientists be registered as ISSS members (application forms to be provided by the SG). It will be appreciated that a 10% of the Meeting Registration fee be transferred to the ISSS Treasury, as retribution for publicity given in het ISSS Bulletin (compare the General Congress) 2. Voting for Officers of the Commissions and Subcommissions To promote fair geographical distribution of Officers, and to avoid past frustrations on procedures at Congress votings in general, a number of by-laws is necessary. (i) All interested ISSS members attending the Commission sessions at the Congress have a right to vote for Officers (note: this is slightly different from Rules H.4 and H.5 which speak of 'attending members of the Commissions' and the next Congress Council should be asked to approve on this). All attendents at the Congress have to be or to become ISSS members. This has however not always been controllable in the past during individual Commission sessions, especially as regards participation of soil scientists from the host country. 68 0) (k) (I) (m) (n) (o) Therefore, congress cards, giving entitlement to voting, will be handed out by the SG/Treasurer at the start of the Congress to alle existing and newly registering members. Voting per Commission is not to take place at the same time, but consecutively, and is duly announced. The congress cards of members participating in the voting are duly stamped with a Commission Seal upon the hand-out of balloting papers. Voting for candidates is secret. The incumbent Chairman of a Commission invites, before or at the relevant Congress session, nominations for new Officers, that are signed by at least ten members. If they wish to do so, the Nacional Societies can propose nominations, provided that it is supported by ten signatories of that Society that are also paidup ISSS members. The signatories or nominees do not have to be present at the Congress : the nominee must however have given written indication of his willingness to stand for election. It is the intention that one of the new Vice-Chairman/men of a Commission should be prepared lo function as Chairman after having served the four-year period. This implies that Commission Chairmen normally serve as such for only one period of four years. The nominations are to be accompanied by a short presentation of the candidate!s) by one of the signatories-nominators, highlighting his merits and involvement in the Commission's affairs. The presentation may include a preview of the programmes that the candidate should like to pursue in the forthcoming period. 3. Nominating Committee (p) Each voter puts down two names of nominees, for each of the three positions lo be filled by election, consecutively; the two names most mentioned for each position will be handed over by the Presiding Officer of the Commission to the general Nominating Committee, for consideration and action as given in Rule H.IO. It is suggested that the President of the Society, as President of the Council, is also Chairman of the (q) Nominating Committee (Rule H.5), The two members from each Commission that shall form part of the Nominating Committee should not be candidates themselves for any of the vacant Officers posts. It is suggested that the immediate Past Chairman or his nominee is one of the two members of the Nominating Committee. (r) After explaining this to attending ISSS members, the Chairman, in consultation with the other Officers of the Commission, proposes two names. If this proposal is not carried by a consensus (show of hands), then the proposal, as well as alternative nominations from the floor provided they are supported by at least 10 attending members, are voted upon in a secret ballot. (s) The Subcommissions do not have the right to nominate members for the Nominating Committee. 4. Duties of the various officers The ( 1 st) Vice Chairman of a Commission, not the past Chairman, lakes over from the Chairman in case of necessity. The 2nd and 3rd Chairmen should take care specifically of participation in the activities of the Society from their geographical area. (t) Similarly, the 2nd and 3rd Past Presidents should take care of participation in the activities of the Society from their geographical area, in consultation with the President and the Secretary-General. 5. Terms of office-holding of Secretary-General, Deputy Secretary-General and Treasurer Rules G.2.b. and G.2.C. may be read to mean that the above Officers hold office undeterminately: unless they themselves decide to resign, their termination of appointment is done by the Council only "if necessary". Because of the vagueness of the wording, this may be embarrassing on both sides and a specification of the procedures seems appropriate. (u) The termination of the assignments of the SG, DSG and Treasurer can be effectuated by non-prolongation on the part of the Officers concerned, or on the part of the Council. The SG should inform the Council at least one year in advance of the next Congress whether the incumbents wish to continue in their respective functions or not. At the same time the SG suggests the forwarding, directly to the President, of any competing or replacing candidale(s). allowing the Council either to confirm the incumbents or to replace them with new Officers. 6. Contacts with National Societies At least one year before the Congress, the SG invites the national societies represented at the Council - i.e. those with at least 20 paid-up members of ISSS - for proposals on Honorary Members (see Rule B.2). (v) If a national society wishes to nominate a soil scientist for Honorary Membership who is not a national or resident of the country concerned, then it is recommended that it invites beforehand the concurrence of the society of the country of which the candidate is a national, where he is living now, or where he has been working for most of his active period. ( w) Also one year before the Congress, the SG asks the national societies for suggestions on future activities of the respective Commissions and Working Groups, including nominations of candidates f or Officers posts that will become vacant. M A similar invitation is to be published in the Bulletin at about the same time, for the benefit of individual members not attached to National Societies, (x) All official contacts between ISSS Commissions or Subcommissions and the respective national units should be copied to the SG. These contacts may include requests of the Commission Chairmen for proposals, by at least 2 paid-up ISSS members of the national units or the national societies, on future programmes on those matters that are of the Commission's specific interest. These requests should be made well before a new Congress (compare rule G.2.f for general affairs). 7. Membership fees and other financial support for the ISSS Secretariat As described in Rule B.l. there are active members, sustaining (corporate) members and honorary members. In addition, there are non-member subscribers to the Bulletin, (y) The annualfees for the first two classes of membership, andfor the non-member subscribers, are laid down from time to time by the Council. As from I st January 1979 they are, in US dollars, as follows : active members $ 5.- ; sustaining members at least $ 25.-; subscribers $ 6.-. Furthermore voluntary contributions of any amount, by sponsors of the Society, are welcomed, (z I ) Honorary members are exempted from payment of fees. 8. Languages The official languages of the Society are English, French and German, in agreement with a Council (z2) resolution of the 5th Congress in Leopoldville in 1954. It implies that changes in this by-law can be proposed and effectuated by any future Council. Notes from the SG : 1 ) I have not been able to find any official reference to such a Leopoldville resolution ; 2) At the founding of the Society in 1924 it was mentioned in the first Rules that English, French, German, Italian and Spanish were the official languages. From 1927 onwards the 'ISSS journal* contained only German, English and French as official languages, though Italian, Russian and Spanish were permitted. After the second world war only English and French were apparently official languages of the Bulletin, till 1954, when German was re-introduced. 9. Emblem and letterhead (z3) The emblem of the Society will figure on the Bulletin and on a standard letterhead to be used by all ISSS Officers, Commissions and Working Groups 10. Registering of the Society and Insurance It is thought by the Committee-on- Rules that at the Seat of the Society - i.e. the address of the SG - there should be a Registered Office where the Rules, and the final By-laws should be officially deposited and registered. It may however be that these Rules do not confirm to the national requirements of the country were the Secretariat is established. Furthermore it is suggested that there should be a contingency insurance for the members of the Organizing Committee of each Congress (and official inter-Congress meeting), or an insurance towards the Society as whole or towards the SG. Also, measures should be taken to safeguard the financial assets of the Society, which at present are in the respective accounts of the Treasurer (in Ghent) and of the Secretary-General (in Wageningen). Right now the Society has no legal means to recuperate these assets in case of accidental or wilful malfunctioning of the ISSS Bureau. The SG will seek advice from a private sollicitor. and also collect information on the legal situation of comparable societies or unions, either directly or through ICSU. 11. Processing and publication of the by-laws (z4) The above proposed by-laws, and any other still to be formulated, will have to be approved or modified by the Council(nol the Congress). The proposed ones will be sent around to the National Societies one year before the New Delhi Congress and can also be published in a pre-Congress bulletin. Any two members wanting changes in the proposals should send their suggestions to their representative in the Council, usually the Presidents of the National Societies.
