| Abstract/Contents: | "In the midwestern U.S., a November application of nitrogen (N) is made to promote turfgrass color and growth the following spring. Weather conditions or work load may prevent or delay this application. Research was conducted to determine if N applications in October, December, or January would provide the same spring turfgrass response as a November application. In a three-year field study, either 49 or 98 kg N ha-1 from urea, sulfur coated urea (SCU), or activated sewage sludge (Milorganite) were applied in the middle of each month from October to January to Kentucky bluegrass (Poa pratensis L.) growing on a Flanagan silt loam (fine, montmorillonitic, mesic Aquic Argiudoll). Clipping weights (yield) and color were monitored the following spring. Significantly higher color ratings and yields resulted from 98 kg N ha-1 compared to 49 kg N ha-1. Urea application in either December or January provided better color and higher yields than an application in November which, in turn, was better than an application in October. Turf color and yield were similar for all application dates or Milorganite, however, the low rate of Milorganite did not result in acceptable turfgrass color the following spring. With SCU, there was a slight color advantage to an application in November compared to October and application in either December or January compared to November. Comparisons between sources for the November application indicated that urea and SCU provided better color and yield than Milorganite. A urea application of 49 kg N ha-1 in November +24 kg N ha-1 in April compared favorably to treatments of SCU or Milorganite at 98 kg N ha-1. Urea, Milorganite, and SCU applied later than November provided spring turfgrass response equivalent to or better than that provided by a November application." |
