| Abstract/Contents: | Study to observe the effects of Turf Restore and Greens Restore (granular materials from the Ringer Corporation) on thatch reduction, water infiltration rates, soil chemistry,and turf quality. Included for comparison are urea and an experimental ISU (ISU Exp) product. Data collected included water infiltration rates, bulk density, salt reduction, cation exchange capacity, nutrient availability, thatch reduction, and turf quality. The study was initiated in May 1988 and will continue over a 3-year period. The turf was established in 1984 on a Nicolett (fine-loamy, mixed mesic, Aquic Hapludoll) soil (pH 7.5, 2.3% organic matter). Twenty-one 5 ft by 10 ft plots of Glade Kentucky bluegrass make up the test area. The turf is irrigated as needed to prevent drought stress. The study was designed in a randomized, complete-block arrangement with three replications each of seven treatments. Three applications were applied throughout the first year(May, July, and September). Application rates and results are provided in tables. No significant differences among treatments, other than visual quality, were found in the study. All treatments provided acceptable visual quality through the latter part of the season. The Turf Restore at 2 pound N per 1000 sq ft and the ISU-2 at 2 pounds per 1000 sq ft provided the highest quality ratings throughout the fall. Are from the first year of planned 3-year study. The lack of significant differences is not unusual in the first year of this type of study. The study will be continued in 1989. |
