| Abstract/Contents: | "Turfgrass specialists recommend that one-time applications of water soluble nitrogen (N) not exceed 49 kg N ha-1; this recommendation is supported mainly by cool-season turfgrass research. This field study assessed root growth of Tifway bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burt-Davy] following ammonium nitrate fertilization. Seven N rates (0, 24, 49, 73, 98, 146, and 195 kg N ha-1) in four replications were applied once to establish turf grown on a modified, high-sand root-zone and mowed frequently at a 25 mm height of cut with clippings returned. The experiment lasted from late spring until fall with measurements taken bi-weekly. Visual turf quality, clipping yields, and concentrations of leaf-blade tissue N, soil nitrate, and soil ammonium increased initially with increasing N rate. Root mass, root length, root density, and total nonstructural carbohydrates generally showed little or no differences among treatments. Root growth did not decrease significantly with one-time applications of a water soluble N fertilizer at up to four times the generally recommended upper rate." |
