Abstract/Contents: | "The high sand content of golf greens creates a rootzone potentially prone to nitrogen (N) leaching. The floating green at the Coeur d'Alene Resort Golf Course, Coeur d' Alene, Idaho, USA is essentially a large, sand-based lysimeter that was in play during the study. Leachate flow (every 30 minutes), daily NO3-N and NH4-N concentrations, clipping dry weight, and clipping percent N were monitored. Leachate samples were also collected monthly with suction microlysimeters installed at high and low contour sites and in a high traffic area. Research objectives were to : 1) quantify N concentration and quantity 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, mean NO3-N and NH4-N concentrations in the leachate were 0.94 and 0.09 mg L-1, respectively. During the growing season the green was foliar fertilized at 0.5 g N m-2 every 7 to 10 days. Additional applications of 1.5,3.0, 3.5, or 4.5 g N m-2 briefly increased leachate NO3-N concentration and quantity of N leached, but never did NO3-N exceed 1.9 mg L-1 during a 60-day post-application period. The highest quantity 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, concentrations differed by microlysimeter location on the green. Low leachate N concentrations and efficient plant uptake of N suggested a low potential for negative environmental impact of N applications on golf greens." |
