Soil organic matter (SOM) is vital for enhancing soil fertility and sustain crop productivity.
Worldwide, the largest pool of terrestrial carbon (C) is contained in soils, and under best
management practices, soils may also have great potential to act as C sinks and assist in climate
change mitigation. However, historic cultivation practices, including tillage, fertilization, and
other management, have exerted significant pressure on agricultural soils' capacity to store and
cycle organic C, leading to reduced soil organic carbon (SOC) stocks. The SOC dynamics in soil
are controlled by complex interactions between various factors such as climate, soil, and
agricultural management practices. We utilized a process-based model, RothC, to simulate longterm
SOC dynamics for rice-based cropping systems under 100% NPK and farmyard manure
management (FYM) practices using the LTFE experiment dataset. The RothC model was
parameterized and validated to predict SOC stock. The validated model was then used to
evaluate the impacts of different management practices on SOC dynamics under different
climatic scenarios. The results demonstrated that management practices with FYM have great
