Discussion

Systematic monitoring shows cumulative effects on soil conservation from varied maize straw incorporation amounts and depths.

Higher straw incorporation amounts significantly enhance soil conservation by accelerating decomposition rates.
Residual straw ratios decreased by 27.4–62.2% with increased amounts and were significantly affected by burial depth.
Time-dependent equations predict soil loss effectively based on incorporation duration and depth, suggesting long-term benefits.
The findings provide a theoretical foundation for optimized management of straw incorporation practices in agriculture.

Zhang et al. (2025) studied this question.
