Technical Abstract: Managed turf accounts for approximately 17 million hectares of land in the U.S. and is the most intensively managed system in the urban landscape. The primary objective of this research effort was to assess the watershed scale hydrologic and surface water quality impact from a well managed golf course. Nutrient and pesticide in surface flow have been collected for two growing seasons (2003-2004). Nutrient load attributed to the course was 0.11 kg ha-1 yr-1 NH4-N, 0.59 kg ha-1 yr-1 NO3-N, 0.14 kg ha-1 yr-1 DRP, 2.79 kg ha-1 yr-1 TN, and 0.27 kg ha-1 yr-1 TP. During the 2-year period, various concentrations of 2,4-D and chlorothalonil have been measured in the surface flow.
