| Abstract/Contents: | "In this study, seven granular nitrogen (N) sources are being evaluated for maintenance fertilization. The turf is Glade Kentucky bluegrass established in September, 1984. It is maintained at a cutting height of 2 inches. The study is replicated three times in a complete block design. Plot size is 3.5 ft X 7 ft. The treatments include six slow-release N sources applied at 4 lb N/1000 ft2/year split into two equal applications. The six slow-release N sources include: IBDU and Plastic Coated Urea (PCU) from Estech Corporation, Sulfur Coated Urea from the Anderson Company (SCU/CIL), Sulfur Coated Urea from the Lesco Company (SCU/TVA), Methylene Urea from O.M. Scotts and Ureaformaldehyde (UF) as Blue Chip from the NOR-AM Company. In addition, one urea treatment was applied at 4 lb N/1000 ft2/year split into four equal applications. Treatments were initiated in the spring of 1985. The dates of fertilizer application are May 1 and August 15. The additional urea treatments were applied on June 1 and September 15. The results of the 1987 data indicate that urea, SUC/CIL, SCU/TVA, and PCU/Estech provided the overall best quality, while IBDU and Blue Chip had the poorest overall quality. SCU/TVA, SCU/CIL, urea and methylene urea produced more clippings following the spring application of fertilizers, whereas, there was no difference in the density of the turf and thatch depth among the treatments." |
