Carbon dynamics, potential and cost of carbon sequestration in double rice cropping system in semi arid southern India

Abstract: Studying the dynamics of soil organic carbon (SOC) is important for understanding the mechanistic pathways of C stabilization into different SOC pools. An attempt was, therefore, made to assess the impact of double rice cropping system with different levels of fertilizers and in combinatio...
