Book (stand-alone)Organic recycling in Africa. Papers presented at the FAO/SIDA Workshop on the Use of Organic Materials as Fertilizers in Africa, Buea, Cameroon, 5-14 December 1977
FAO Soils Bulletin 43
1980Also available in:
No results found.Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the t wo-week Workshop. These covered: 1- Cropping systems and crop residue management 2- Biological N-fixation 3- Research, training and extension. A central theme much emphasized at the Workshop was the fact that agricultural policy makers, technicians and scientists need to study more closely the basic practices of the small farmers so that proposal for the introduction of new systems could be easily understood, integrated and accepted by these farmers. -
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)Improved use of Plant Nutrients. Report of the Expert Consultation on Better Exploitation of Plant Nutrients, Rome, 18-22 April 1977
FAO Soils Bulletin 37
1978Also available in:
No results found.FAO organized an Expert Consultation in April 1977 with participants from countries consuming both a high and low quantity of fertilizer, to identify possibilities for a more intensive and rational utilization of the valuable plant nutrients in mineral and organic fertilizers, with emphasis on conditions in developing countries. The conclusions reached should serve interested countries as a guide for follow-up activities in the more rational use of plant nutrients at the research and practical l evel. The participants were convinced that there are still ample possibilities for improvement and for making the costly and sometimes scarce plant nutrients more efficient and their use more economic.
