Abstract
Carbon is one of the basic elements in the universe and found virtually everywhere on earth: in the air, the ocean, soil and rock. Among this, the largest portion of active carbon holds in soil. Plants take carbon from the air and convert it to plant tissue, some of which returns to the soil as plant residue. To improving soil quality, increasing crop yields, and reducing soil loss, soil carbon management plays an important role. Capture and store carbon in the soil helps to improve soil health and productivity, and stabilize the global carbon cycle, benefiting agricultural production sustainably. To assess the carbon accumulation capacity of seven cropping systems (Rice-Groundnut, Rice-cotton, Rice-Rice-pulse, Rice-pulse, Rice-Rice, Rice-maize, Rice-Rice-Sesame), the post-harvest soil (PHS) sample were collected during 2021 in Chidambaram block, Tamil Nadu, India, and determined the pH, EC, Bulk Density (BD) and Organic Carbon (OC). Among the seven cropping systems PHS tested Rice-pulse and Rice-Rice-Pulse cropping sequences recorded higher organic carbon content of 3.94% & 2.93% respectively. From this study, it can be concluded that inclusion of pulses in rice-based cropping system increased the yield of succeeding crops with higher carbon accumulation capacity (CAC).
