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.
