Abstract/Contents:"Research was initiated to evaluate both individual and interactive effects of cultural practices on the leaf and soil nitrogen content. The investigation was conducted on a 'Penncross' creeping bentgrass turf under the simulated traffic conditions from 1989 to 1991. Traffic simulation was applied as 5 passes of the wear simulator over the turf twice weekly during the growing season. A split-split-plot experimental design was used. Daily or biweekly irrigation, clipping return or removal, and 5, 15, or 25 g N m-2 yr-1 were the main-, sub-, and sub-sub-plot treatments, respectively. Treatments were replicated 3 times in a randomized complete block design. Soil and leaf tissue nitrogen content were evaluated twice in 1989 and three times in 1990 and 1991. Both individual and interactive effects on the leaf nitrogen content were observed under the trafficked conditions. In the irrigation frequency x nitrogen treatment interaction response of 1989, leaf nitrogen content quadratically increased from 3.51 to 3.94% with nitrogen rates in combination with daily irrigation treatment. In plots treated with high-N (25 g N m-2 yr-1), approximate 4% more leaf nitrogen content was associated with daily irrigation rather than biweekly irrigation. The nitrogen rate treatment was effective in leaf tissue nitrogen content in both 1990 and 1991. In 1990 leaf nitrogen content quadratically increased from 3.50 to 4.25% with nitrogen rate. High-N treatment (25 g N m-2 yr-1) was a significant contributing factor to leaf tissue nitrogen content. The high-N treatment plots had 21% and 10% more leaf nitrogen content in 1990 and 1991, respectively, when compared to low-N treatment plots (5 g N m-2 yr-1). Leaf nitrogen content varied with time after establishment. At the low-N level treatment (5 g N m-2 yr-1), plots sampled in 1991 had 20% more leaf nitrogen content, as compared to plots sampled in 1990. With the high-N rate (25 g N m-2 yr-1), plots analyzed in 1991 were 8% higher than that of plots analyzed in 1990. Accordingly, superintendent could gradually reduce annual amount of nitrogen application in the turfgrass management with time after establishment, based on soil and leaf tissue analysis. Different responses between trafficked and nontrafficked turfs demonstrate result from the turfgrass research under the nontrafficked conditions should be carefully used, when recommended to the sports turf, depending on the intensity of traffic. Strategic management approaches are strongly recommended for the sports turf from a standpoint of the traffic intensity."
