Abstract

This trial is a continuation of similar experiments that were cut short in the fall of 2018 due to unseasonably cold and snowy weather. The 2018 experiments began with Recovery Plus 4 applied at 0, 4, and 8 oz/1,000 ft2. These rates caused extreme chlorosis on the research plots. Rates then were reduced to 0, 1, and 2 oz/1,000 ft2, resulting in less, but still unacceptable, levels of chlorosis. In a third run of the trial, rates were further reduced to 0, 0.25, and 0.5 oz/1,000 ft2, but applications were not begun until October 27, thus prematurely ending the trial shortly thereafter due to dormant turf caused by extreme cold weather. While last year’s trials had application dates seven days prior to, at, and seven days post aeration, the 2019 trial had applications at only seven days pre- and post-aeration. In addition, treatments were added that involved Amino Pro V.
