Effects of Different Tillage Practices on Soil Stability and Erodibility for Red Soil Sloping Farmland in Southern China

Tillage practices significantly influence soil nutrient retention, structure, and stability. However, the impact of tillage on stability erosion resistance through perturbation approach structure remains unclear. This study aimed to establish universal principles across slope surface profile scales. We evaluated effects various practices, including conventional (CT), compaction (CM), subsoil (ST), no (NT), (SCM) in China’s red hilly region. Soil stability, resistance, other properties were quantified using field surveys laboratory experiments. discovered significant variations aggregate (SAS), wet (WAS), mechanical (SMS), erodibility (SE) among five methods. The K factor’s average value indicated that 0–40 cm layer was more erodible for CT (0.472) than methods, with NT (0.26) being least erodible. (0.43) most effective treatment reducing SE, while SCM (0.41) enhanced fertility, controlled mitigated machinery-induced risks. CM (0.38) maintained without improving storage, ST (0.33) improved such as alleviating hardening caused by CM. results provide reference parameter values selecting appropriate methods decrease degradation enhancing productivity a
