Soil organic carbon (SOC) is the largest among three major carbon pools of global ecosystems. During the past few years, global warming and forcible land-use changes have resulted in a huge loss of this major carbon pool and as a consequence, concentration of atmospheric CO2 has increased. To mitigate the potential risks arising from atmospheric abundance of CO2, adoption of carbon sequestration strategies at different landscape scales is a major option. For this purpose, proper estimates of SOC stock per unit area are essential. In this study, we have estimated the SOC stock of a typical agricultural farm from hot arid ecosystem of India and also its spatial variation within the farm.
