Nitrogen Not Imminent Threat To Groundwater (Distributed May 2004) A recent Florida study showed that a sodded St. Augustine lawn, even on a sandy soil with 10 percent slope, was very effective in retaining the applied N (nitrogen). Sod was fertilized with a standard 1 pound. N/1000 square feet. every other month during the growing season. Researchers found less than 2 percent of the applied N was lost as leaching down through that soil. This loss occurred essentially with fresh applications and higher rainfall.
