Abstract:
Creeping bentgrass (Agrostis palustris Huds. ‘Cobra’) was subjected to simulated traffic at the equivalent rate of 50,000 golf rounds per year on a mature sand-based green. Cultural practice treatments were applied to evaluate mitigation of the impact of the traffic. Treatments were core cultivation (2 times yr-1), vertical mowing (2 times), and K (0 and 24 kg ha-1, 6 times yr-1) and N fertility (24 and 73 kg N ha-1, 6 times yr-1) alone and in all combinations. Visual quality, clipping yield, Dollar Spot expression and Localized Dry Spot persistence were evaluated. High N rate produced higher quality and greater clip yields than under low N. During the first year of the study under high N, treatments with K demonstrated better quality. By the third year differences were less distinct. Core cultivation produced slightly lower quality, but differences from other treatments were negligible. Dollar spot and Localized Dry Spot symptoms were expressed more under low N rate than high N regardless of other treatments.
