Technical Abstract: Quantification of nutrient and pesticide losses from managed turf systems (golf courses) is scant. A study was initiated at Northland Country Club in Duluth, MN, in 2003 to quantify nutrient and pesticide losses in surface and subsurface discharge waters. Based on the four years of data collected at this site, runoff plus tile flow from this course was equivalent to 47% of the precipitation. Nitrogen losses from this course are minor compared to agricultural cropland systems. However, phosphorus concentrations measured in the discharge water were comparable to those from other land managements and suggest the need for thorough soil sampling prior to additional phosphorus application. Pesticide (2,4-D and chlorothalonil) concentrations and loads were consistent with those previously reported on plot scales.
