Managing soil fertility in the tropics: a resource guide for participatory learning and action research

This Resource Guide is based on extensive work done in several African countries. It is intended to provide user-friendly ways to gather, manage and analyse information and data by applying participatory learning and action research, and to suggest ways to use this knowledge to develop strategies for integrated soil fertility management. It can best be seen as a toolkit.
