Water Conservation Practices Mitigate Nutrient Losses from Turf – Deficit Irrigation and Fertility Effects on NO3–N Exports from St. Augustinegrass

Dense, healthy turfgrass can retain properly-applied nitrogen fertilizer with minimal nutrient loss to the environment. In the southern U.S., urban water conservation strategies often include reduced irrigation programs which can diminish the health and density of turfgrass temporarily. In a two-year field study, researchers investigated the effects of water-conserving irrigation practices on runoff volume and nutrient losses from turf.
