Technical Abstract: Tile drainage discharge from managed turf is known to carry elevated concentrations of agronomic fertilizers and chemicals. One approach being considered to reduce the transport is end-of-tile-filters. Laboratory and field studies have been initiated to address the efficacy of this approach. Results from the laboratory study indicated that the filters were able to significantly reduced the amount of dissolved phosphorus, chlorothalonil, and metalaxyl. The amount of nitrate removed was minimal. Results from the field study, indicate significant reductions in ammonium, nitrate, total nitrogen and total phosphorus. The end-of-tile filters show significant promise to reduce pollutant loads. This would be important for golf course superintendents who need to protect their surface waters and comply with regulatory and/or permitting laws.
