Book Description
The Biology and Agronomy of Stylosanthes covers the proceedings of the 1982 International Symposium on The Biology and Agronomy of Stylosanthes, held in Townsville, Queensland, Australia. The symposium aims to present the developments in the research of the economically important genus, Stylosanthes. Comprised of three parts encompassing 31 chapters, the book discusses Stylosanthes taxonomy, genetic resources, plant-environment interaction, and agronomy. The opening part discusses the taxonomic problems, evolution, and cytogenetic studies of Stylosanthes species. This part also considers the natural variation and distribution, Brazilian species, and existing collection of the genus. The second part of the book presents available data on the occurrence of water shortage in plant tissue and how plants react to it. This part also deals with other environmental constraints to growth and survival, the mineral nutrition, reproductive physiology, and diseases and pest problems of Stylosanthes. A discussion on the influence of mycorrhiza and rhizobium in the genus is also included. The concluding part examines the effect of seed biology on initial pasture establishment and the population dynamics of established pastures. Considerable chapters in this part are devoted to the agronomical aspects of the genus, including nitrogen inputs; chemical composition and nutritive value; and animal and seed production. The book further presents data on global ventures in Stylosanthes, including agricultural projects, research and development, breeding programs, and productivity programs in various regions. This book is an ideal source of information for biologists, agronomists, scientists, and researchers.

Book Description
Fertilizer is a vital component of strategies for expanding foodproduction. The rapid growth in population and the widening food deficits inmany tropical countries ofAsia, Africa, and Latin America call attention to those aspects of fertilization that have been neglected but are expected to yield large economic payoffs in the future. Fertilizer sulfur falls into this category. In the past fertilizer sulfur received little attention from researchers and policymakers since sulfur deficiency was not considered a serious problem. It was not a problem because of low crop yields, extensive cropping, and the incidental supply of sulfur through rain, irrigation water, manures, and sulfurcontaining fertilizers. However, the situation has changed in the last three decades. Moder nagriculture based on high crop yields, intensive cropping, improved crop varieties, and greater use of sulfur-free fertilizers and environmental regula tions restricting sulfur emissions are creating large gaps between sulfur sup ply and sulfur requirements. Sulfur deficiencies are widespread and grow ing. Consequently, the full potential of a modern agricultural system in tropical countries is not being realized. This research effort results from the recognition of the seriousness of the sulfur problem and its adverse impact on food production as well as IFDC's dedication to the development and transfer of economically ef ficient fertilizer technology to tropical countries. This study represents a comprehensive analysis ofthe technical and economic linkages between fer tilizer sulfur and food production, and it provides guidelines for future directions in fertilizer sulfur research and public policy.

Book Description
Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

Book Description
The world population in 1930 was 2 billion. It reached 3 billion in 1960, stands at 4. 6 billion today, and is expected to reach 6 billion by the end of the century. The food and fiber needs of such a rapidly increasing population are enormous. One of the most basic resources, perhaps the most basic of all, for meeting these needs is the soil. There is an urgent need to improve and protect this resource on which the future of mankind directly depends. We must not only learn how to use the soil to furnish our immediate needs, but also ensure that the ability of the soil to sustain food production in the future is unimpaired. This is indeed a mammoth task; a 1977 United Nations survey reported that almost one-fifth of the world's cropland is now being steadily degraded. This volume is the first of a new series entitled Advances in Soil Science. The diversity of soil makes it necessary for research to be conducted in many locations. There are basic principles, however, that are universal. This new series will present clear and concise reviews in all areas of soil science for everyone interested in this basic resource and man's influence on it. The purpose of the series is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifYing additional research needs.

Book Description
Retaining the successful formula of the first edition while placing additional emphasis on tropical environmental conservation, this new updated edition considers the response of tropical food crops to environmental factors such as climate, soil and farming system.
