| Abstract/Contents: | "Excess nutrients in surfaces waters can result in undesirable consequences. Experiments were designed to quantify phosphorus and nitrogen transport with runoff from plots maintained as a golf course fairway to identify which cultural practice, solid tine or hollow tine core cultivation, will maximize nutrient retention at the site of application and reduce nutrient concentrations in adjacent surface waters. The study found: Runoff volumes and amounts of ammonium nitrogen, nitrate nitrogen, and soluble phosphorus transported with runoff were less from turf managed with hollow tines than solid tines. Concentrations of nitrogen in a surface water receiving runoff from turf, managed with either solid tines or hollow tines, were below the drinking water standard for nitrate nitrogen (10 mg L-1) and levels associated with increased algal growth (1 mg L-1). Only surface water concentrations associated with hollow tine core cultivation 2 days prior to runoff displayed concentrations of phosphorus below the water quality criteria to limit eutrophication in streams draining into lakes and reservoirs (0.05 mg L-1). Regardless of the cultivation practice, concentrations of phosphorus in a surface water receiving turf runoff exceeded levels associated with increased algal growth and eutrophication within a lake or reservoir (0.025 mg L-1)." |
