| Abstract/Contents: | "Poa supina Schrad. (supina bluegrass) has increased in use as a turfgrass in the northern United States and Canada in recent years due to its aggressive stoloniferous growth habit, and exceptional shade tolerance. Unfortunately, the majority of supina bluegrass management of is largely based on hearsay; particularly optimum nitrogen fertility and mowing heights are not well documented. The objective of this study was to determine the appropriate nitrogen fertility requirements for supina bluegrass grown on a Capac loam soil (Fine-loamy, mixed, mesic Aeric Ochradqualfs) with and without simulated traffic stress. Three nitrogen fertility rates of 10, 20 and 30 N g N m-2 year-1 were compared at both a 1:1 and 2:1 ratio of nitrogen to potassium over four years. Turfs were subjected to simulated fall athletic field traffic stress each of the fours years using a Brinkman Traffic Simulator and compared to turfs receiving no simulated traffic stress. After four years, when supina bluegrass was fertilized at 20 and 30 g N m-2 year-1, little difference occurred between the two rates for turfgrass color, cover, quality, and shear strength. Therefore, fertilizing at 30 g N m-2 year-1 would not exhibit any adverse effects, but would be considered unnecessary. Fertilizing at 10 g N m-2 year-1 was too little and no significant differences occurred between the two N:K ratios, or the traffic and non trafficked treatments. Finally, it is important to remember that adequate nitrogen fertilization can be obtained for supina bluegrass grown on a Capac loam soil (Fine-loamy, mixed, mesic Aeric Ochardqualfs) with 20 and 30 g N m-2 year-1, but the 20 g N m-2 year-2 rate would be more environmentally sensitive and economically practical." |
