Abstract

Consequences of soil erosion include water and air pollution, reduced land productivity from loss of topsoil and nutrients, and degradation of the environment. Vegetative barriers are grass, shrubs, or small trees grown in close rows that can be used to control both water and wind erosion by providing protection from soil and dislodging sources such as rainfall, and offering a semipermeable barrier to erosion agents resulting in soil deposition. The resultant vegetation also shields the soil surface from overland flow and decreases the erosive capacity of water flow by reducing its velocity.
