Book (stand-alone)Soil and plant testing and analysis as a basis of fertilizer recommendations
FAO Soils Bulletin 38/2
1980Also available in:
No results found.General principles of plant nutrition don't furnish the concrete information, necessary for practical treatments in a given situation. Thus, the questions arise which parameters must be considered an how can they be determined. This leads to consider the concepts of nutrients diagnosis, as well as the methodology and the corresponding equipment and instrumentation, for putting it into practice. The question may arise whether plant or soil analysis should be used for diagnosis crop nutrient requ irements and making fertilizer recommendations.Both methods may be complementary, not competitive and the laboratories should be in the possibility to carry out both types analysis. It is recommendable to start soil analysis prior to plant testing.There are many possibilities and methods for testing soil chemical and nutrient properties. It is indeed highly recommended to agree on a minimum of uniformity of methodology. -
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)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.
