An erosion control product made by shredding on-site woody materials was evaluated for mitigating erosion through a series of rainfall simulations. Tests were conducted on bare soil and soil with 30, 50, and 70% cover on a coarse and a fine-grained soil. Results indicated that the wood product known as wood shreds reduced runoff and soil loss from both soil types. Erosion mitigation ranged from 60 to nearly 100% depending on the soil type and amount of concentrated flow and wood shred cover. Wood shreds appear to be a viable alternative to agricultural straw. A wood shred cover of 50% appears optimal, but the appropriate coverage rate will depend on the amount of expected concentrated flow and soil type.
一种通过现场粉碎木质材料制成的侵蚀控制产品，通过一系列降雨模拟试验来评估其减轻侵蚀的效果。试验在粗粒土和细粒土上的裸土以及植被覆盖率分别为30%、50%和70%的土壤上进行。结果表明，这种名为木屑的木质产品减少了两种土壤类型的径流和土壤流失。根据土壤类型、集中流量和木屑覆盖量的不同，侵蚀减轻幅度在60%至近100%之间。木屑似乎是农业秸秆的可行替代品。50%的木屑覆盖量似乎是最佳的，但合适的覆盖率将取决于预期的集中流量和土壤类型。
