Abstract/Contents:"Based on the observation of high nitrate levels in the agro-ecosystem, the public perceives that golf courses and other intensively managed turfgrass areas as sources of surface and ground water contamination. However, relatively few field studies have addressed the fate of nitrogen applied to golf courses. This field experiment, conducted at an intensively managed golf course in Pinehurst, North Carolina, determined soil solution nitrate concentration as a function of landscape position, soil depth, and season. Seventy-two suction cup lysimeters for four transacts and six landscape positions were installed in the fairways, roughs, and adjacent non-play areas at 30, 60, and 90- cm soil depths. Soil water samples were collected weekly from August 1999 to February 2001. Nitrate concentration was highest at the surface and decreased with depth. Higher concentrations were found on the fertilized fairways (0.1 to 79 NO3-N) and roughs (0.1 to 59 NO3-N), whereas unfertilized non-play areas contained the least (< 10 mg L-1). Low NO3-N concentrations adjacent to a lake suggests substantial denitrification losses. We conclude that NO3-N concentrations fluctuate seasonally and across the golf course landscape as a result of fertilization and management practices."
