英文摘要Manure returning (OMR) and straw returning (SWR) practices are widely adopted to enhance soil organic carbon (SOC) sequestration, whereas the effects are minimal in cold black soil areas. The issue may be a mismatch between environmental factors and the choice of returning material, which remains unclear. Here, six sites (each site process manure and straw returning croplands) in the western Northeast China Plain (Fuyu, Longjiang, Tailai, Baiquan, and Kedong Counties, and Nehe City) were chosen to investigate the impact of soil properties (soil clay content [Clay], initial soil pH values [pH], and initial soil organic carbon concentration [initial SOC]), management practices (years of fertilization [Year] and carbon input [C input]), and climate factors (mean annual temperature [MAT], mean annual precipitation [MAP] and mean annual wind speed [WS]) on soil organic carbon concentration (SOCc). The results showed that in Longjiang and Tailai Counties, OMR had a significantly higher than SWR on SOCc, whereas in the other four sites, OMR was significantly lower than SWR on SOCc. Redundancy analysis (RDA) and variance partitioning analysis (VPA) revealed that with OMR, climatic factors, management practices, and soil properties accounted for 40.8 %, 34.9 %, and 20.6 % of the SOCc, respectively. While with SWR, these factors explained 53.6 %, 12.6 %, and 31.2 %. Among variables, WS was the most influential variable affecting SOCc changes under OMR, with MAP ranked second in importance. For SWR, Clay and MAP were identified as the two most importance factors. Additionally, SOC is accrul in the part of silt and clay (<0.053 mm) under OMR. For SWR, SOC is accrul in the part of macro-aggregates (>0.25 mm). Thus, for organic materials returning, improving soil water management can promote increased SOCc. And matching sandy soils to SWR and controlling wind speed during OMR can increase SOCc effectively. Match organic material returning to multiple factors, emphasizing climate, can lead to more effective increases in SOCc.
