Abstract/Contents:"Excess nutrients in surface waters may result in enhanced algal blooms and plant growth that can lead to eutrophication and a decline in water quality. The application of fertilizer to golf courses may be a source of nutrients to surface waters. Runoff studies were conducted to measure applied nitrogen and phosphorus loss in runoff from creeping bentgrass (Agrostis stolonifera L.) turf managed as a golf course fairway. Quantities measured in the edgeof- turf runoff were used to calculate surface water concentrations of a pond receiving runoff from turf. Runoff and surface water concentrations were compared with water quality standards to evaluate potential environmental effects of turf runoff. Key observations of the study were: Less than 12% of the applied ammonium nitrogen, nitrate nitrogen, or soluble phosphorus was measured in the runoff. Time between hollow tine core cultivation and runoff (2, 11, 15, or 63 days) did not significantly influence the percentage of applied nitrogen and phosphorus transported in the runoff. Phosphorus concentrations in runoff were greater than water quality criteria to limit eutrophication. Nitrogen concentrations in runoff were greater than levels associated with increased algal growth, while nitrate nitrogen concentrations were below the drinking water standard to prevent blue baby syndrome. Phosphorus concentrations in a pond receiving runoff remained above levels associated with increased algal growth and eutrophication of lakes. Nitrogen concentrations in a pond receiving runoff were below levels associated with increased algal growth."
