A newly completed study by the University of Florida shows that following some simple steps can keep your lawn looking green and help keep fertilizer from running into lakes, rivers and streams across the state. UF/IFAS researchers tested St. Augustine grass and three other lawn grass species at three locations around the state. The goal was to determine the amount of nitrate and phosphorus leaching that would occur under a variety of conditions. This study shows that applying fertilizer to healthy turf at the recommended rates resulted in extremely low rates of leaching. The eight-year study was funded by a 4-million dollar grant from the Florida Department of Environmental Protection.
