Green manure-rice rotation is an effective strategy for enhancing crop productivity and increasing soil organic carbon (SOC) stocks. However, the mechanisms driving SOC accumulation in functionally distinct fractions remain unclear. This study examined the response of particulate and mineral-associated organic carbon (POC and MAOC) to a green manure-rice-rice (GM) rotation in two long-term field experiments with contrasting clay contents (silty clay loam and silt loam).
