Water And Nutrient Balances Of Vegetative Treatment Systems For Feedlots In South Dakota, Daniel T. Ostrem

Electronic Theses and Dissertations

Vegetative treatment systems (VTS) are a possible alternative to storage basins for managing feedlot runoff but have not been researched in South Dakota. This study was conducted to evaluate the performance of VTS within South Dakota. The performance was evaluated by determining water and mass balances on each vegetative treatment area (VTA). The balances were determined by measuring all inflow, outflow, evapotranspiration, precipitation, and both soil and water nutrient concentrations within the VTA. Twelve site years have been completed in researching VTS from four feed lots in South Dakota. Seven of the twelve site-years VTS were able to prevent water …
