Resumen
Descripción
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.
