Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.

Soil fertility is one of the most important factors regulating yield and productivity in both the agricultural and natural ecosystems of the tropics, and maintaining soil fertility has become a key challenge to sustainable development in this region. This book presents the ecological processes and management practices which affect soil fertility and then looks at ways to integrate this knowledge to develop economically feasible solutions. Based on a symposium held at the University of Zimbabwe in May 1996, the volume is partly the result of ten years of research by the Soil Biology and Fertility Project in Zimbabwe and includes contributions from researchers in Africa, Asia, Europe and North America. The book is divided into five sections covering nutrient dynamics in soil, decomposition of crop residues, tree-soil-crop interactions in agroforestry and in ecosystem dynamics, and prospects for the future. Essential reading for agronomists, soil scientists and ecologists studying the tropics, this volume is also an important reference for decision-makers in land use and development in tropical countries.

Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
