Abstract:
A “study was conducted on the Alfisols under” rice-based cropping system of Korea district of Chhattisgarh in order to identify sustainable rice-based cropping” system, and “to develop soil quality index for monitoring soil health” in the area. The data indicated that, The data indicated that, the studied soils are classified in sandy clay loam soils, which is slightly good for plant growth and development. The bulk density, particle density and porosity were found in optimum levels. The large amount of organic carbon was added by rice chickpea cropping system, might be responsible for optimum levels of soil bulk density, particle density and porosity. The soil moisture content from 25.16 to 38.38 (mean 31.34) was found followed with available water holding capacity ranged from 36.23 to 48.32 (mean 41.37) percent respectively. The higher root biomass of rice chickpea cropping system increased macro-aggregate formation. The soils of the studied area fall under acidic in nature, might be attributed to acidic parent material along with legume based cropping system that make soils acidic in nature. The organic carbon range was within medium to high in category, could be attributed to high carbon sequestration capacity of rice-chickpea cropping system. The available N, P, and S were found in medium category, whereas, the available K was found in high level. All the biological properties were fall under higher Level, which indicated that the rice-chickpea cropping system under Alfisols is suitable for maintaining soil quality and environmental sustainability.
