Abstract/Contents:"Late fall or early winter N fertilization of turfgrass provides many benefits. In cold winter climates, such as eastern Washington or the midwestern U. S., early to mid-November fertilization is usually recommended. In western Washington, where winter temperatures are mild and growth continues, there is no standard fertilization practice. The objective of this study was to compare fall/winter fertilization in the mild winter climate west of the Cascades to a true cold winter climate east of the mountains. Identical treatments were applied in Puyallup (western) and Pullman (eastern) Washington. Five different fertilizer sources [none, ammonium sulfate, IBDU, polymer coated sulfur coated urea (PCSCU), polymer coated urea (PCU)] were each applied on four different dates (November 1, December 1, January 1, February 1) for two winters. The rate was 74 kg N/ha. In Pullman, November was the most effective time to fertilize. Later applications yielded few winter color benefits and slower spring green-up. In Puyallup, November and December applications were both effective. January and February fertilization resulted in limited response. Ammonium sulfate was most effective in Pullman, but coated urea sources produced better response in western Washington. PCSCU was better in early winter, while PCU lasted longer into the spring."
