The SDI system was installed in Duplin County, North Carolina, at the location of an innovative swine wastewater treatment system. The effluent from the treatment facility was applied to Bermuda grass forage crop at agronomic nutrient rates. Treated wastewater application below the soil surface reduces nutrient loss potential through volatilization and places nutrients in the rooting zone. Results from the forage SDI system indicated that treatments receiving treated waste as their nutrient source had higher biomass yields.
