Abstract

【Objective】Clarifying the mechanism of water erosion on the mineralization of soil organic carbon (SOC) in soil aggregates is of great significance for enhancing soil carbon sequestration capacity.【Method】This study investigated the soil on eroded slopes in the southern red soil region, measuring the SOC mineralization characteristics of soil aggregates at different slope positions and different particle sizes. Combined with the first-order kinetic model parameters of soil aggregate SOC mineralization, further analysis of the soil factors affecting soil aggregate mineralization was conducted.【Result】The results indicated that the cumulative mineralization of soil organic carbon (SOC) increased rapidly within the first seven days of incubation and then stabilized, with significantly higher values in the deposition zone(508.3 mg/kg) compared to the erosion zone (328.2 mg/kg). The mineralization at the top of the slope and the bottom of the slope were significantly higher than that in the middle of the slope. The contribution of SOC mineralization from soil macro-aggregates (66.57%) was significantly higher than that from micro-aggregates (14.38%). The C0 and k values showed a trend of bulk soil > macro-aggregates > micro-aggregates, and the values at the middle slope position were significantly lower than those at other slope positions. Additionally, a significant negative correlation was observed between the content of (0.25,2] mm aggregates and the mineralization of SOC in soil aggregates.【Conclusion】The study demonstrates that water erosion significantly affects the mineralization of SOC in soil aggregates, enriching soil organic matter in the deposition zone, accelerating the transformation of soil macro-aggregates into micro-aggregates, and promoting the mineralization of SOC in soil aggregates. Meanwhile, the content of (0.25,2]mm aggregates and clay particles reduced the mineralization of SOC in soil aggregates.
