In-situ crop residue composting: A potential alternative to residue burning


Author(s): Swarnima Shrivastava and Vinay Arya

Abstract: In India, the potential of crop residues is a serious concern and more efforts need to be made to estimate food grain production and availability of crop residues. This review reveals that crop residues of cultivated crops are an important resource and not only as a source of of nutrients for crop production hence also improving the various soil physical, chemical, and biological properties and functions, soil and water quality. Large quantities of crop residues produced in the rice-wheat cropping system in India are a potential source for improving soil carbon sequestration, nutrient cycling. Burning of crop residues is a threat to sustainability concerns. Disposal of rice straw is usually done by burning in open field but this practices resulted in large amount of air pollutants (i.e. CO2 and NO2.) and including loss of nutrient. In-situ incorporation of crop residues into the soil for composting is the most common and important technology for the management of agricultural residues. It reduces the volume and weight of agro-residues about 50% consequently produce a stable product (humus) which enhance the physico-chemical and biological properties of the soil. Recycling of rice residues constitutes more potential problems than recycling of wheat straw. Incorporation of wheat residues, increased the yield of rice and also had a positive residual effect on the yield of subsequent wheat crop. It is suggested that in each cropping system, the constraints to production and sustainability should be conceptualized and identified to guide toward the best option. A multidisciplinary and integrated efforts by all agriculturalist are needed to design a system approach for best choice of crop residue management system which enhance both agricultural productivity and sustainability
