The utilization potential and the environmental effects of applying swine manure and swine lagoon effluent to tall fescue were evaluated for four years. Lagoon effluent was applied to 9 in. X 9 in. plots by weekly sprinkler irrigations during the growing season while swine manure slurry from an under-slat pit was applied to a similar plot four times per year. Treatments were chosen to evaluate the acceptable maximum application rate, which is important when land area for application is limiting. The results indicated that swine manure and swine lagoon effluent can be excellent sources of nutrients for fescue, but water quality considerations, NO3(-N) levels in the forage, stand persistence and long-term soil effects must be evaluated when determing acceptable maximum application rates.
