Abstract :
Soil organic carbon pools are important in maintaining soil productivity and influencing the CO2 loading into the atmosphere. Agricultural soils can mitigate the problem of carbon concentration increase in atmosphere if proper management practices are involved. In the present study, total carbon stock in crops and soil was analyzed for two years along with crop rotation practice to observe its impact on the carbon pool. For that two agricultural fields C12 and D7 were incorporated with different crop rotations for two years and on the basis of this SOC, Total Carbon, soil respiration and carbon stock were measured. In the end of the study C12 showed higher biomass carbon stock (2.61 t ha-1) as compared to D7 (1.98 t ha-1) and also higher total carbon stock (plant+soil) (40.09 t ha-1) as compared to D7 (38.30 t ha-1). Results prove that
agriculture can not only be the source but also an effective sink if it is properly managed with different crop rotation practices and also with no-till practice.
