In the 1980s and 1990s, green manure/cover crop (GMCC) systems became a popular agricultural technology in research and development efforts for smallholder tropical and subtropical farmers. However, few syntheses of these experiences have been conducted. This volume of case studies contributes to bridging this gap by reviewing field-level experiences with these systems. Twelve case studies are included. Eleven of them describe experiences from Latin America (4 cases), Africa (6 cases) and Asia (1 case) and the twelfth case reports on the development of a GMCC systems database. Two concluding chapters, `Learning from the Case Studies' and `Future Perspectives', build upon the cases. The systems described are diverse. Some systems have been spontaneously adopted by farmers, while others have been introduced to the farmers through diffusion efforts. Some of the cases reviewed describe small, localized efforts while others report on large-scale, well-known ones, such as the combination of GMCCs and conservation tillage in Santa Catarina, Brazil, the maize-Mucuna system in northern Honduras, and the improved fallow systems in Eastern Zambia. Most experiences include both development and research aspects and to the extent possible the cases integrate these two. Discussion of the strengths and shortcomings of the systems and efforts is frank, and the goal is to learn from these experiences to benefit future efforts. It is expected that both researchers and development practitioners and students of tropical farming systems and soil management will find this volume of case studies useful.

Excerpt from Green Manures and Manuring in the Tropics: Including an Account of the Economic Value of Leguminosae, as Sources of Foodstuffs, Vegetable Oils, Drugs, &C It is my pleasant duty to introduce to the agricultural public the work of M. P. de Sornay on the tropical Leguminosae. M. de Sornay, originally a student at the Agricultural Station, has for the past nine years been attached to the staff as Assistant Director. The family of the Leguminosae contains a large number of species whose practical applications, chiefly in warm climates, are of great interest, and M. de Sornay's treatise on them is the best proof of the extent of his knowledge and his zeal. We cannot but be indebted to the author for having put together such a mass of information in so concise and instructive a form. Besides a description of the characters and practical uses of tropical Leguminosae, the reader will find a study of the peculiar agricultural properties of this family, which forms a special class of its own in the vegetable kingdom. Clear and simple in plan, and unencumbered by useless comments, it contains a scholarly account of the subject tempered by the sound judgment of the writer. His personal contribution is of the greatest value. This contribution consists of numerous analyses of plants, an account of the observations on the cultivation of each, the advantages to be derived from them, and their manifold uses in industry and agriculture. Once read the work cannot fail to be appreciated. There is no doubt as to the future success of this book of M. de Sornay, and I am happy to have this opportunity of offering him my congratulations and of assuring him of my esteem.
