Towards sustainable land use Dr. P. Folstar, Member of the TNO Board of Management Dr. M. Popp, Chairman of the Board of Directors of Research Centre Karlsruhe (FZK) Ten years ago, in 1985, TNO initiated the First Conference on Contaminated Soil in Utrecht. At that time, a rather complete inventory of suspected contaminated sites existed in The Netherlands. Time had come to consider further actions for investigations, evaluation and remediation. This concern has been spreading ever since to other European countries and throughout the world. In particular, German scientists and authorities soon recognized the significance of this problem, and consequently joined TNO in organizing and funding a forum for discussions in a series of conferences. Following three venues in German cities, the 5th conference in Maastricht, a Dutch as well as a European city, marks the increasing interest in the international scientific and political community. Application of the concept of sustainable development to soil as an essential element of human existence requires an answer to the question how to meet the needs of today's generation without impairing the possibilities of mankind in the future. As we do not know the needs of the future, especially regarding the functional requirements of soil use, we can hardly do better than starting from the present priorities. This can not mean to guarantee the quality of soil functions everywhere at any time.

In recent years, viticulture has seen phenomenal growth, particularly in such countries as Australia, New Zealand, the United States, Chile, and South Africa. The surge in production of quality wines in these countries has been built largely on the practice of good enology and investment in high technology in the winery, enabling vintners to produce consistently good, even fine wines. Yet less attention has been paid to the influence of vineyard conditions on wines and their distinctiveness-an influence that is embodied in the French concept of terroir. An essential component of terroir is soil and the interaction between it, local climate, vineyard practices, and grape variety on the quality of grapes and distinctiveness of their flavor. This book considers that component, providing basic information on soil properties and behavior in the context of site selection for new vineyards and on the demands placed on soils for grape growth and production of wines. Soils for Fine Wines will be of interest to professors and upper-level students in enology, viticulture, soils and agronomy as well as wine enthusiasts and professionals in the wine industry.

Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

New methods of conserving moisture and soil that increase production are of importance to the war effort in which the farmers of the United States are engaged as this publication goes to press. It is fortunate that the facts presented in this bulletin on the use of crop residues have been established at such an opportune time.
