Abstract/Contents:"Nonpoint sources of pollution are the leading cause of water-quality problems that adversely affect drinking water supplies. Transitioning from turfgrass systems to other lawn types can lead to an accumulation of soil nitrogen (N) and phosphorus (P) that may be lost following irrigation or rainfall. An experiment was conducted at the West Florida Research and Education Center, Jay, FL to evaluate the effect of turfgrass removal on N and P leaching. In April 2021, plots containing drainage lysimeters covered with either common centipedegrass (Eremochloa ophiuroides Munro) or 'Floratam' St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] were stripped using a sod harvester. After one week, the plots were planted/covered with three alternative landscapes which included forbs, 'Pensacola' bahiagrass (Paspalum notatum Flugge) + 'Ecoturf' rhizoma (Arachis glabrata) perennial peanut, and woodchip mulch as a nonliving ground cover. The plants selected for the forb mixture included sunshine mimosa (Mimosa strigillosa Torrey & A. Gray), coreopsis (Coreopsis lanceolata), frogfruit (Phyla nodiflora), and centipedegrass. Undisturbed plots serve as the untreated controls. Leachate samples were collected weekly by removing all leachate water by vacuum extraction for volume determination and acquiring a water sample for NO2 + NO3, NH4, and ortho-P determination. Predisturbance soil nutrient concentrations were higher in St. Augustinegrass compared to centipedegrass. Those differences were not reflected in nutrient leachate loads following disturbance and ortho-P leachate was not detected in any treatment. Preliminary data suggest that the conversion process does not have an immediate effect on N or P leaching. However, nutrient leaching levels in the undisturbed plots remained near zero whereas N leaching was detected in the disturbed plots. This suggests that leachate differences may be observed over time."
