Proceedings of the ISSS symposium on water and solute movement in heavy clay soils [antikvár]

PREFACE At the 12th International Congress of Soil Science, held in New Delhi, India in February 1982, a proposal by the Dutch Soil Science Society to host an international symposium on water movement in heavy clay soils was accepted. The symposium was to be sponsored by the International Society of Soil Science (ISSS). To further develop contacts between pedologists and soil physicists, it was decided that the symposium be organized by Commissions I (Soils Physics) and V (Soil Genesis, Classification, and Cartography) of the ISSS. Later, it was also agreed that the symposium be co-sponsored by the European Geophysical Society. In the fall of 1982 an organizing committee was formed consisting of G.H. Bolt (Chairman), J. Bouma (Secretary), and W.A. Blokhuis, J.W. van Hoorn, P.A.C. Raats, K. Rijniersce, and G.P. Wind (members). The ISSS was represented on an ad hoc basis by its Secretary General W.G. Sombroek. Secretarial assistance was provided by Mrs. M. Rijk of the Netherlands Soil Survey Institute. At its first meeting the organizing committee decided to expand the scope of the symposium to cover not only water but also solute movement in heavy clay soils, thus including aspects of ISSS Commission II (Soil Chemistry). The three-day symposium was held from 27 to 29 August 1984, at the International Agricultural Centre, Wageningen, The Netherlands. Organizational aspects were handled by Mrs. L. Hotke and Mrs. E. van de Wetering. The schedule included a reception given by the Dutch Ministry of Agriculture and Fisheries, a visit to the International Soil Reference and Information Centre (ISRIC) in Wageningen and, of course, a symposium dinner. Following the symposium were two day-long excursions. The first, oL-ganlsad by K. Kijiiiersce of the IJsselmeerpolders Development Authority, was to very young clay soils in a newly-reclaimed polder. The second, to young and old riverine ^^ clays near the Rhine, was organized by M. Kooistra, J.H.M. Wösten,
