Pressure to reduce pesticide use has spawned an interest in the use of compost as a soil amendment, fertilizer and to suppress certain plant diseases. Compost tea is defined as the product of showering recirculated water through a porous bag of compost suspended over an open tank with the intent of maintaining aerobic conditions. In our study the two teas investigated had various carbon additives designed to stimulate specific microbial reactions during the brew process. Teas were brewed for twelve weeks over three seasons and applied either as a soil drench (3600 l ha-1) or as a foliar spray (360 l ha-1) with a nitrogen gas pressured spray system to an annual bluegrass and creeping bentgrass sand based putting green. The microbial and nutrient analysis of the teas were monitored during the study and revealed that the tea had little to no nutritive value and highly variable microbial analysis. Soil microbial analysis was monitored before and after treatments, as well as turf quality and disease incidence throughout the study. No significant difference was observed for soil microbial measurements for the drench treatments during the study. Turf quality ratings initially were very low for the tea drenches, therefore it was decided to apply liquid fertilizer over the tea treated plots to maintain acceptable turf quality. This addition masked any further differences in turf quality. The foliar tea applications suppressed dollar spot 40 to 60 percent when compared to untreated plots in one of three years. It is unlikely that due to the variability of brewing results, little microbial benefit, and the labor required for brewing tea that this technology will see widespread adoption in its current form.
