Abstract/Contents:"Researchers at the University of Georgia are using different fertilizer sources at varying rates to determine the potential for leaching of plant nutrients from golf greens and nutrient runoff from fairways. Their findings include: Nitrogen was found to leach at a faster rate than phosphorus, and at low rates, leaching of phosphorus was not different than control. Controlled-release fertilizers do not appreciably retard phosphorus leaching, but nitrogen leaching can be reduced by using controlled-release sources. Nitrogen may be sequestered in the organic layer of greens during the first years after building. Subsequently an equilibrium is established in the layer between sequestering nitrogen and mineralization of nitrogen by microbes. The first rain event after a fertilizer application will produce the great majority of the transport by runoff water both of phosphate and of whatever form of nitrogen was applied. 'Watering-in' should help reduce transport as should applying fertilizer when siginificant rainfall is not expected for several days. Runoff from fairways is a greater threat to water quality than drain outlets from greens and tees because of higher fairway acreage, higher slope of fairways, and higher application reates for fairways. The quantity of nitrogen and phosphate transported from turf is linearly related to the rate of application, and runoff volume is linearly related to soil moisture before a rainfall event."
