| Abstract/Contents: | Evaluated the performance of 13 granular nitrogen (N) sources. This study was established in June 1988. The grass is a Park Kentucky bluegrass that was established in the fall of 1987. It is mowed at 2 in and watered to prevent drought stress. The treatments include urea, urea + .25% NBPT, urea + .50% NBPT, sulfur-coated urea CIL, sulfur-coated urea TVA, O.M. Scott sulfur-coated urea, IBDU (fine), Blue Chip, Milorganite, Triazone experimental (a product of Arcadian), methylene urea 41-0-0, Nu Tech, ISU experimental (organic N source), and a control with no fertilizer. All treatments were applied at 1 lb N/1000 ft2 on June 6, August 15, and September 15. This study is replicated three times in a randomized, complete-block design. Plot size is 4 ft by 8 ft. Monthly visual quality ratings are provided in a table with least significant difference values. The fertilizers containing high levels of water insoluble N, i.e. IBDU, Blue Chip, and Milorganite, were slow to greenup. All formulations of urea, sulfur-coated urea, and methylene urea provided immediate green color. In addition, the urea formulations, sulfur-coated urea, and methylene urea fertilizer sources generally provided better quality throughtout the growing season. |
