Research Project: MANAGEMENT OF A VEGETATIVE TREATMENT SYSTEM TO REDUCE NUTRIENTS IN BEEF CATTLE FEEDLOT RUNOFF

Location: Agroecosystem Management Research

Project Number: 5440-12630-001-02
Project Type: General Cooperative Agreement

Start Date: Oct 01, 2010
End Date: Jul 31, 2013

Objective:
1) Develop a vegetative treatment system to treat runoff from a beef cattle feedlot; 2) operate the system in conjunction with a real-world production environment; 3) evaluate the effectiveness of the treatment system to remove nutrients, pathogens, and pharmaceutical compounds from the runoff.

Approach:
An eight cell vegetative treatment area will be used to treat runoff from a beef cattle feedlot. Feedlot runoff water collected in small basins will be pumped onto the cells at defined rates, and water and soil samples will be collected. Experiments with clean groundwater will also be used to examine the effect of clean rainfall runoff from the cells.
