| Abstract/Contents: | Second year of a 2-year study designed to compare the effects of three fertilizer sources and three water dilution rates on fertilizer burn. The three fertilizer sources include N-Sure, formolene, and urea. Each fertilizer source was diluted into 1-, 2-, and 4-gal of water/1000 ft2. Each fertilizer/water dilution rate was applied to a 5 ft by 5 ft plot at a rate of 1 lb nitrogen (N)/1000 ft2. Treatments were applied on Kentucky bluegrass (Poa pratensis) cv. Ram-l. Irrigation was provided to the plots to prevent drought stress. All plots were maintained at a cutting height of 2 in. Treatments were applied on July 29, 1988, and August 8, 1988, on separate sites. The fertilizer sat in solution for seven days before the July 29, 1988, treatment and two hours before the August 8, 1988, treatment. Visual quality data were collected four days after fertilizer application. Visual quality for this study is measurement of discoloration due to fertilizer treatments. Results are provided in a table. There was significant interaction between fertilizer source and water dilution rate for the August 8 application date. Formolene diluted into 1 gal of water caused significantly more injury than when diluted in either 2 or 4 gal of water. The temperatures during this time period were extremely hot. N-Sure applied at the same date did not cause any appreciable damage. In summary, urea caused the most burn damage at all water dilution rates, while N-Sure caused the least amount of injury. Leaving the formolene in solution for over seven days obviously caused polymerization, thereby lessening damage. |
