Description

Vegetative buffer strips are vegetated areas (usually strips) between fields and waterbodies that can mitigate the effects of agricultural activities by acting as a physical barrier to sediment and nutrients being carried to streams, and thereby have been widely used as a best management practice (BMP). Buffers can slow surface water flow and allow greater water infiltration, trapping the sediment entering from cultivated areas. In addition, research has documented the ability of buffers to removing pollutants from surface runoff and/or shallow groundwater (Lin et al., 2007; Ryder and Fares, 2008). For example, nitrogen can be removed by plant uptake or by microorganism denitrification within buffers (Lowrance and Hubbard, 2001).
