Critical aspects of organic matter management in the Tropics: the example of India

摘要: Organic matter is the life of soil. It enables a soil to perform efficiently its primary function supporting plant growth. Its endemic deficiency in tropical soils, particularly those under influence arid, semiarid and sub-humid climates, major factor contributing their low productivity. Research over past 30 years, formatted as long-term experiments, has conclusively proven that treatments practices supported organic build-up, also favored sustainable Since sustenance necessitates regular additions, bolstering supplies sufficient quantities strategy suggested for future. While in-situ cultivation non-competitive use are common elements an overall scheme on reinforcing reservoir, traversal routes harnessing, however, vary with kind resource being aimed at. For instance: cattle dung human excrements, conversion into biogas considered necessary; farmer participatory appraisal emphasis dual purpose legumes found be essential spreading green manures, non-palatability pre-composting step seem vital succeed crop residues. Possible research, development policy initiatives outlined enlarge supply efficient different types resources.
