The above workshop is organized with the following objectives. • To discuss major soil fertility management constraints, and relevant extension approaches. • To discuss synergetic relationship between agricultural research and extension services. • To exchange views on the appropriate participatory approaches to soil fertility management and fertilize/use With partlcular reference to the Farmers Field Schools, as an innovative extension approach • To propose modalities for effective cooperatio n between private and public sectors for delivery of extension to soil and plant nutrients management at farm-level.

Soil and plant testing and analysis as a basis of fertilizer recommendations
FAO Soils Bulletin 38/2
1980

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.

Soil survey investigations for irrigation
FAO Soils Bulletin 42
1979

Also available in:

No results found.

The pressing need for increased agricultural production in the years ahead can only be met by more efficient use of our land and water resources including more widespread and better irrigation in those regions where rainfall is inadequate. Production gains will be shortlived unless the attendant hazards of salinization, water logging and lowered fertility are kept in check by effective planning and management based on a thorough understanding of the soil conditions. Soil survey and land classifi cation are generally accepted essential preliminaries to investment in irrigation development. This publication aims to describe the special requirements of soil survey for irrigation development, and assumes that the reader is familiar with basic soil science and soil survey techniques.
