Abstract/Contents:"The high sand content of golf greens creates a rootzone potentially prone to nitrogen leaching. Research was conducted on the floating green at the Coeur d'Alene (Idaho) Resort Golf Course, the green is essentially a large sand-based lysimeter. Objectives were to: 1) quantify N concentration and amount in leachate, flow, and percent N recovered and 2) determine if microlysimeter data were correlated with that obtained from the whole-green system. During 1998-1999, NO3-N in the leachate was 0.94mg/L (range 0.09 to 2.68 mg/L). During the growing season the green is foliar fertilized at 0.5 g N/m2 every 7 to 10 days. Additional applications of 1.5, 3.0, 3.5, or 4.5 g N/m2 briefly increased leachate NO3-N concentration and total N leached; however, never did NO3-N exceed 1.9 mg/L. Highest amount of N leaching occurred, late fall and early spring, when flow was high and grass growth was minimal. Microlysimeter NO3-N concentrations were correlated with whole-green results; however, concentration differed by microlysimeter location on the green. Low leachate N concentrations and efficient plant uptake of N suggests low potential for negative environmental impact."
