Training in plant nutrient assessment

This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends: (a) training farmers and women's groups in plant nutrition management, with special emphasis on topsoil conservation and production; (b) training extension officers and researchers in plant nutrient management, cropping systems and farming systems, and in economic evaluation of plant nutrient impact.
