Abstract/Contents: | "Most homeowners have a tendency to use too much water to irrigate their lawns to try and maintain a desired level of aesthetics. This research study was used to compare how a fertilizer product blended with a surfactant would affect turf quality in comparison with the fertilizer without the surfactant and an untreated control under moisture stress. The study was setup on a stand of tall fescue (Festuca arundinacea) with five replicates that were subjected to drought conditions. The changes in quality throughout the trial were measured using the ratio of red and infrared light (R/NIR), the normalized difference vegetative index (NDVI), visual ratings of quality, visual wilt percentage (VWP), and soil volumetric moisture content (VMC). The surfactant + fertilizer treatment plots had significantly higher VMC compared to the untreated control plots. There was no statistical difference in VMC between the fertilizer alone and the surfactant + fertilizer treatment. The surfactant + fertilizer treatment significantly improved tall fescue growth and development compared to the fertilizer alone treatment. Overall the surfactant + fertilizer treatment had significantly higher NDVI values for both years compared to the fertilizer alone and untreated control treatments. The R/NIR ratio for the surfactant + fertilizer treatment was significantly lower than the fertilizer alone and untreated control treatments for both years. The higher NDVI and lower R/NIR values indicated that the turf experienced less stress in the surfactant + fertilizer treatment and was more healthy compared to the fertilizer alone and untreated control treatments. The plants in the fertilizer alone treatment exhibited significantly higher wilt percentages between irrigation cycles compared to the surfactant + fertilizer treatment." |
