From the Preface: "This soils bullet in provides training material on composting for extension workers and teachers in countries in the tropics and subtropics. The objective is to promote the use of locally available organic materials to increase soil organic matter content for the improvement of soil fertility, and as sources of plant nutrients in conjunction with mineral fertilizers. This manual is written for all those concerned with the maintenance and improvement of soil fertility, especially under tropical and subtropical conditions. It is hoped that it will be of value to staff in government agricultural advisory services and in non-government agencies both at the policy making level and in various levels in extension services. It contains material for use in farmer training. Those involved in planning safe waste disposal systems will also find it useful and it should stimulate thinking among elected officials in local government bodies throughout the tropics. Schoolteachers in rural areas will be able to base science lessons on it. The manual has been written in simple language without detracting from the scientific basis or level of technology involved. This has been done deliberately to enable those whose mother tongue is not English to use it and also to form a bridge between scientific knowledge and practical compost production. The severe drought and famine in parts of Africa in 1985 have shown the necessity for adequate soil organic matter to prevent hillside erosion and to retain moisture in the soil for crop growth. The cost of mineral fertilizers and their relative scarcity in some areas has increased the need to recycle waste organic materials as sources of crop nutrients. This Bulletin explains the basic composting process, suitable organic wastes, practical composting methods, use of the product in a variety of situations and a consideration of economic and social benefits. It also deals with approaches to practical extension work with farmers on the subject.".

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - These proceedings contain the papers presented at the Fourth International Conference on Finite Elements in Water Resources, held in June, 1982, at the University of Hannover, Federal Re public of Germany. This Conference continued the successful series of previous conferences held at Princeton University in 1976, at Imperial College in 1978, and at the University of Mississippi in 1980. Since Finite Elements have proved to be a powerful means for analysing water resource problems, the principal objective of the Conference was to provide an exchange of experiences in practical applications of the finite element method and to establish a forum for discussion regarding accuracy, economy, limitations and improvements. Related discretization methods were included within the scope of the Conference. New develop ments in numerical and computational techniques, basic mathe matical formulations, and soft- and hardware aspects were considered to be equally important topics for an exchange of ideas between both theoretically and practically oriented re searchers. The Conference Organizing Committee is very grateful to the many distinguished scientists who attended the Conference, and for their contributions towards the proceedings. This collection of papers in being made available to a wider audience of en gineers and scientists by CML Publications in Southampton, U.K.
