Soil organic matter content and several fractions of soil organic carbon are considered to be sensitive indicator of soil health who on several conditions like cropping choice and management practices. The presence of different soil organic C pool in rice cultivating soils are well documented but thoroughly studied information on relation between soil C status and different rice based cropping managements are not available. Total organic C, water extractable organic C, humus C, microbial biomass C and total carbohydrate analyzed on the soils of long term cultivated rice fields for this study. Three rice based cropping systems like rice-rice, rice-wheat, and rice-fallow from semi-arid climatic zone of west Bengal were chosen for this purpose. | Different rice based cropping systems can influence various soil organic carbon pools in a clay loam soil of west Bengal
