Mono-cropping, burning of crop residues, imbalanced fertilization and limited use of farm
manure are resulting in loss of soil organic carbon (SOC). In this study, integrated soil-crop
management (ILMsoil), improved management (IMsoil) and conventional management (CMsoil)
was studied to enhance the soil carbon sequestration for mitigation of greenhouse gas
(GHG) emissions. The life cycle assessment (LCA) approach was used to estimate carbon
footprint from successive crops of rice, mustard and jute with or without intercrops or mixed
crops. The adoption of ILMsoil helped in reducing the carbon footprint by 78%. The overall
economic yield increased by 25% over IMsoil as well. Net CO2-eq emission was 68% less
under ILMsoil as compared to other systems. The reduction in net LCA-GHG emission was
mainly due to high SOC sequestration by jute crop and leguminous intercrops and mixed
crops. Improved crop diversification and agronomic productivity as used in ILMsoil system
may decrease the inputs of non-renewable energy and consequently reduce the emission of
GHGs from agroecosystems. Improvement of soil health, minimization in nutrient and water
losses, and application of the increased amount of organic fertilizers were found helpful in
reducing the carbon footprint. ILMsoil method of cultivation in 0.70 million hectare of jute
growing area may reduce about 0.40 million tonnes of CO2-eq from atmosphere every year
and provide carbon credit of 1.22 million US$to the farmers of eastern India.
