Crop management practices largely govern the complex process of carbon (C) sequestration in agricultural soils. In rice-based systems, small alterations in cultivation practices can lead to increased soil organic carbon (SOC) contents in soil and reduced GHG emissions, thereby complementing the C sequestration. Due to enormous complexity of C sequestration process, monitoring soil C changes could be costly and extremely variable in C stocks on micro- and macro-scales. To assess the soil C change, the factors driving the driving soil C dynamics are accounted, and models are developed. However, it is worth notable that these modelling and measurement efforts are relatively new considering the history of C dynamics. It will be challenging to settle on annual-to-decadal target rates for rebuilding soil C based on the available modelling and measurement tools. Overall, change in soil C fraction is reported in many studies with choice of agronomic management practices in rice-based cropping systems. The combined application of inorganic fertilizers and organic manures seems to be the best option to increase rice yields while improving soil C accumulation. An attempt has been made in this chapter to compile and analyse all the available information related to the soil C sequestration potential of rice-based cropping system, particularly rice-wheat and rice-rice cropping system, in addition to the mechanism, measurement and valuation of C. © The Editor(s)(if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
