Abstract
The effectiveness of the soil as a receptor for the concentrations of nutrients and organics in periodic high rate flood applications of liquid swine wastes was investigated. A lysimeter was used for collecting soil percolate waters after flood application of liquid waste or tap water and after rainfall in order to test the soil as a high-rate physical and biological filter for liquid swine wastes. Samples of the saturated flow were removed at depths of 25, 50, and 75 centimeters in the profile and tested for concentrations of chemical oxygen demand, ammonium nitrogen, chloride, total phosphate, and sulfate. The concentrations were compared with the concentrations of the applied liquid to determine net decrease of concentration through the soil profile. Results indicated that flood irrigation can lead to groundwater pollution.
