Diversification of rice growing areas in Eastern India with integrated soil–crop system management for GHGs mitigation and higher productivity
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...

| description | 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. |
