Book (stand-alone)Soil and plant testing and analysis. Report of an Expert Consultation, Rome, 13-17 June 1977
FAO Soils Bulletin 38/1
1980Also available in:
No results found.Methods for evaluating nutrient status in order to obtain better plant growth and increased yield are constantly being developed and improved. New analytical techniques and procedures for soil and plant analysis have been invented and tested in many countries and laboratories. There have been innovations in data processing leading to preparation of more refined and specific fertilizer recommendations. The purpose of the Consultation was: i. to review advances in a) methodologies for soil and plant chemical analysis, and b) interpretation of the results obtained and the preparation of fertilizer recommendations based on these results. ii. to identify progress made and areas requiring further attention with regard to the organization of soil testing services in general and, in particular, in developing countries. -
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. -
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.
