Biochar modulates microbial- and plant-derived carbon distribution in soil aggregates: Enhancing organic carbon sequestration in paddy fields across different water management practices

These data are the original data of the observation of soil organic carbon (SOC), soil aggregate distribution, and plant and microbial derived carbon (C). These data advance our understanding of the mechanisms by which biochar (B) amendment increases SOC sequestration and provide guidance for optimizing C management strategies in paddy fields across different water management practices (FI (flooded irrigation) and CI (controlled irrigation)).
