| Abstract/Contents: | "Urea frequently is applied to turfs in liquid formulation at low water application rates which enhance potential foliar N uptake. This study was conducted to evaluate foliar N uptake by several cool-season turfgrasses treated with urea applied at low water volume (35 ml · m-2). Urea was applied foliarly to 8 turfgrasses at 2.5 g N m-2 in 35 ml m-2 of water. Verdure was harvested prior to treatment and after treatment at 24, 48, and 72 hr. Total N-uptake increases were primarily a response to increased the percentage of N, since dry matter production was stable for each turfgrass throughout the 72 hr. Maximum N-uptake occurred 24 hr after treatment. Any significant decrease in N-uptake over time suggested N-movement out of the sampling zone. Turfgrass species and cultivars showed differences in total N-uptake which resulted from initial variations in dry matter, percentage of tissue N, and variations in N-uptake rate. The percentage of N recoveries ranged from 31% to 61% for 'Park' Kentucky bluegrass and 'Highlight' chewings fescue, respectively. Cultivar differences indicated that 'Baron' Kentucky bluegrass was more efficient in relation to foliar N-uptake than 'Park' Kentucky bluegrass." |
