| Abstract/Contents: | "The purpose of this study was to evaluate the performance of 13 granular nitrogen fertilizer sources. The treatments are listed in Table 38 and Table 39. The treatments were applied at a rate of 0.5 lb N/1000 ft2 on May 29, June 26, July 24, and August 20 to a creeping bentgrass 'Penncross'/Poa annua green. The testing area was located at the Hyperion Field Club, Johnston, Iowa. The plot consisted of a randomized, block-design replicated three times. The plots were mowed daily and irrigated as needed. Visual quality data was collected weekly. Visual quality ratings were based on a scale of 1 to 9, with one being equivalent to straw brown turf and 9 equal to dense green turf (Table 38 and Table 39). The fertilizers containing higher soluble nitrogen, Country Club, (Country Club + NIAD, Scotts + Minors, and Scotts + Manganese) had higher consistent average visual quality ratings above 6.0, dipping below 6.0 one or two times. Scotts + Manganese had the highest overall ratings and remained deep green in color during the entire 1990 testing season. The second-most noticeable dark green turf was obtained by using Scotts + Minors. Both fertilizers maintained a 7.0 or above rating for most of the 1990 testing season. The rest of the fertilizers used were slow release nitrogen sources and showed ratings of 5.0 or 6.0 the first part of June. From mid-July through October the slow-release fertilizers showed turf with ratings of at least 6.0 or above." |
