what is a vegetative treatment area
A VTS can be an economical alternative to runoff retention (holding) ponds for controlling runoff from an open lot feeding production system (feedlots). A Vegetative Treatment Area (VTA) is an area of perennial vegetation, such as a grass or a forage. The VTA is used to treat runoff from a feedlot or barnyard. It treats runoff by settling, infiltration, and nutrient use. A VTA is commonly confused with vegetative buffer (or filter) strips.
