The methodology of this project aims at developing an efficient, yet effective, means of providing various nitrogen fertilizer sources to turf grass with the ultimate goal of maintaining sufficient biomass production while minimizing the use of excess nutrients that may eventually end up contaminating our groundwater and waterways. Nitrogen is the nutrient required in the largest quantity by plants, and also poses the greatest threat when nutrient leaching and water contamination are considered. For this experiment, Bermuda grass and Tall Fescue turf plots are treated with either: quick release nitrogen fertilizer, slow release N fertilizer, or a control (no fertilizer). Data collected from each plot consists of dry weight biomass yield, turf quality rating (based on % cover, color and vigor of each plot), as well as analysis of water samples sequentially collected from no tension lysimeters located below the turf's root zone of each treatment plot. Analysis of biomass and water samples will help in determining the nitrogen use efficiency of the turf, as well as the leaching potential of each nitrogen fertilizer source. Turf quality ratings will judge the all important aesthetic quality. Preliminary data from two years reflects that slow release nitrogen fertilizer had the most positive impact in reducing overall biomass production, reducing nitrogen leaching below the root zone, and improving the turf color throughout the growing season compared to quick release fertilizer (urea) and the control.
