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.
