Groenier, James Scott; Foltz, Randy B.; Showers, Charles . 2005. Using Rainfall Simulators To Test Wood Shreddings for Erosion Control. 0571 2329P. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center. 6 p.
Describes the use of a Purdue-type rainfall simulator to test erosion control when wood shreddings were applied to a sandy loam soil in a soil plot frame positioned at a 30-percent slope. When shreddings were applied at 70-percent coverage, they reduced erosion from simulated rainfall and overland flows by five times compared to bare soil. The advantages of shreddings compared to straw are that they do not introduce new weeds to an area, are not eaten by deer and elk, generate less dust than straw, and can make use of wood that might otherwise fuel wildland fires. This tech tip is part of a series that includes Shredding Small Trees To Create Mulch for Erosion Control (0471–2335–MTDC) and Wood Strands as an Alternative to Agricultural Straw for Erosion Control (0423–1302P–SDTDC).
