The management of organic matter in tropical soils: what are the priorities?,. They are the interface between rocks, biota, water and the atmosphere and are therefore a pivotal element of ecosystems. Dryland soils are particularly vulnerable (Katyal and Vlek, 2000) — a problem recognized by the establishment of the Convention to Combat Desertification (www.unccd.org) in 1994

The role and function of organic matter in tropical soils,nt function of OM in soil is as a reserve of the nitrogen and other nutrients required by plants, and ultimately by the human population. Other important functions include: the formation of stable aggregates and soil surface protection; maintenance of the vast array of biological functions, includin

(Tropical) soil organic matter modelling: problems and prospects,al and organic components of the soil and the relations with the vegetation are poorly understood. In such situations, the use of models is an important research tool to explore the relations between the various components, to increase insight into processes, to examine the consequences of managemen

SOM management in the tropics: Why feeding the soil macrofauna?, clues to techniques that would optimise their activities through organic matter management are suggested. Soil macroinvertebrates can consume almost any kind of organic residues in mutualistic association with soil microflora. Significant amounts estimated at several T per ha of predominantly easil

Management of organic matter in the tropics: translating theory into practice,substrate for synthesis of soil organic matter (SOM). The organic inputs in many tropical farming systems such as crop residues, manures, and natural fallows are currently of low quality and insufficient quantity to maintain soil fertility hence there is need to find alternative or supplementary sou
