Vegetative filter strips (VFS) are areas of either planted or indigenous established vegetation situated down slope from open feedlots and settling basins. that VFS may be used to improve the quality of feedlot runoff. They can be incorporated into pastures, grassed waterways, terraces, or cropland. VFS have been shown to remove up to 60 to 70 percent of the suspended solids load, and up to 70 to 80 percent of nitrogen, phosphorus, and chemical oxygen demand (COD) from settled feedlot runoff when designed and operated properly.
