Crop residues and the litter layer

Crop residues and the litter layer (Roose and Ndayizigiye, 1997) play a more prominent role in controlling erosion than does tree s hade cover.
Therefore, the ground cover plays an important role in protection against erosion (Elwell and Stocking, 1976), through the following functions: (1) it intercepts rain, neutralising its kinetic energy and splash erosion; (2) it s lows runoff and reduces its carrying capacity; (3) it improves soil structure by incorporating organic matter (plant debris) and by the biological activity associated with its decomposition, thus increasing structural stability and, therefore, resistance to soil erosion.

哈得盖。因此，地面覆盖着防侵蚀的重要作用（Elwell和放养，1976），通过以下功能：（1）它拦截雨水，中和其动能和溅蚀；（2）它的低流量，降低其承载能力；（3）它改善土壤结构，将有机物（植物碎片），并与它的分解的生物活性，从而增加了结构的稳定性，因此，抗土壤侵蚀。
