Interpretive Summary:

Technical Abstract: Land application of poultry litter as fertilizer may lead to impaired surface and ground water quality. An experiment was conducted at Crossville, AL to study the effects of alum [Al2 (SO4)3,14H2O] treatment of broiler litter on the yield and nutrient uptake of tall fescue (Festuca arundinaceae) and the nutrient content of runoff water exited from treated plots. Alum treatments had no effect on tall fescue dry matter yield, and the herbage nutrient concentrations were within acceptable limits. We noted significant reductions in the runoff concentrations of NH4-N (28.6 mg/L for untreated litter VS 15.0 mg/L for alum-treated litter), total P (11.5 mg/L VS 5.1 mg/L), soluble reactive P (10.4 mg/LVS 4.7 mg/L) , and particulate P (1.9 mg/L VS 0.8 mg/L). This practice should receive serious consideration as a method of reducing the adverse environmental impact of broiler chicken production when the litter is applied to pasture land.
