1978Also available in:
No results found.The Study Tour was financed by the UNDP and had the following objectives. To gain knowledge and experience in: - The multiplication of Azolla as a source of biological nitrogen, particular attention being paid to propagation of Azolla and its protection form disease, insect damage and adverse climatic conditions. - Harvesting and agricultural use of Azolla. - Contruction of small-scale biogas units. - Management of biogas units and efficient use of the gas by farming communities and of the effluents for improving soil fertility -

Also available in:
No results found.The need for developing suitable feeds based on locally available inexpensive ingredients has been widely recognized. Since lack of trained personnel is the main constraint in the development of fish feed technology in developing countries, the FAO/UNDP Aquaculture Development and Coordination Programme (ADCP) organized a special training course in fish feed technology at the College of Fisheries, University of Washington, Seattle, with a view to forming a small corps of fish feed specialists wh o could then be the focal points for future feed development programmes in their respective countries. The first report of the training course was presented in the report ADCP /REP/79/8. This present volume represents the edited texts of lectures presented by different specialists. Some additional material has been included for more complete coverage of the subject. Together, these texts may be considered to constitute a manual on fish feed technology, even though they were not prepared for that purpose. Twenty-six papers are included, under the general headings: (1) Digestion, physiology and anatomy; (2) nutritional bioenergetics; (3) nutritional biochemistry; (4) feedstuffs; (5) feed formulation; (6) feed manufacturing technology; (7) practical diets; and (8) quality control. Appendices include conversion tables, electrical data, and details on pelletability of selective feedstuffs, pellet die specifications, and equipment requirements for an 8 ton an hour feed mill. -
Book (stand-alone)China: recycling of organic wastes in agriculture. Report on an FAO/UNDP study tour to the People's Republic of China, 28 April - 24 May 1977
FAO Soils Bulletin 40
1977Also available in:
No results found.In China the research group visited Peking, the Provinces of Jiangsu, Guangdong, Hebei, Shanxi and the municipality of Shanghai. The member of the group were deeply impressed by the agricultural, economic and cultural achievements of the People?s Republic of China. They gained valuable experience, especially in the field of recycling of organic wastes in agriculture which will be most useful in the development of agriculture in their own countries. The major part of the report is devoted to the main subject of the Study Tour and it emphasizes the practical aspects and applicability of the methods studied in China. At present, about two-thirds of the total nutrient intake is derived from natural manures and heavy reliance on these manures will continue because the Chinese have developed a long standing experience in matching the various types of organic manures to their local soils. While mineral fertilizers are relatively costly, organic manures are constantly available locally at litt le or no cost except in manpower.
