Book (stand-alone)Soil management: compost production and use in tropical and subtropical environments
FAO Soils Bulletin No. 56
1987Also available in:
No results found.The objective of this Soils Bulletin is to promote the use of locally available organic materials to increase soil organic matter content for improvement of soil fertility, and as a 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 contains material for use in farmer training. 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 econo mic and social benefits. It also deals with approaches to practical extension work with farmers on the subject. -
Book (stand-alone)Organic materials and soil productivity in the Near East. Papers presented at the FAO/SIDA Workshop on the Use of Organic Materials for Improving Soil Productivity in the Near East. Alexandria (Egypt), 9 Oct 1978
FAO Soils Bulletin 45
1982Also available in:
No results found.This Bulletin contains the papers and proceedings of the FAO/SIDA Workshop on Organic Materials and Soil Productivity in the Near East. In view of the important complementary effect of organic materials to mineral fertilizers and their role in improving the soil?s physical properties, the Workshop has dealt with a wide variety of items on techniques and uses of the organic materials and wastes including, composting, bio-fertilizers and biogas, the environmental and health aspects, and action g uidelines for follow-up activities in the Near East countries. The purpose of this Workshop was to promote and maintain interest in the use of organic materials for improving soil productivity in the Near East Region and to assist Member Countries in developing action programmes to achieve these goals. The proceedings of the workshop present sound recommendations, the implementation of which would assist in improving the soil productivity, raising crop production levels and producing a bette r quality of life. -
Book (stand-alone)Application of nitrogen-fixing systems in soil improvement and management
FAO Soils Bulletin No.49
1982Also available in:
No results found.In view of the continuing increase in cost and scarcity of mineral fertilizers resulting from the use of high-cost fossil energy, there is renewed interest in organic recycling and biological nitrogen-fixation to improve soil fertility and productivity. The workshop in Alexandria recommended the further promotion of research, development, application and dissemination of information available on various aspects of biological nitrogen-fixation, including symbiotic systems of rhizobia/legume and Azolla/blue-green algae, and free-living nitrogen-fixing bacteria and blue-green algae. It is hoped that the compilation of various aspects of nitrogen-fixation under one cover in this Bulletin will be of interest and assistance to research workers and extension planners concerned with the further development and refinement of these natural systems for soil improvement and management.
