| Abstract/Contents: | "A study was conducted in Alabama to determine P removal by overland flow of swine lagoon effluent on bermudagrass (Cynodon dactylon L. 'Russel') and annual ryegrass (Lolium multiflorum Lam). Treatments included ammonium nitrate at 560 kg N ha⁻¹ yr⁻¹, three rates of lagoon effluent which provided 560, 1120, and 2240 kg N ha⁻¹ yr⁻¹ and 71, 142, and 284 kg P ha⁻¹ yr⁻¹, respectively, and a control. Experiments were conducted at 5 and 10% slopes on a Marvyn loamy sand (fine-loamy, siliceous, thermic Typic Kanhapludults). The length of slope from application site to collection site was 6.1 m. Surface runoff was collected and sampled monthly for dissolved and sediment P. The results indicated that higher concentration of P were found during the early spring and summer seasons when treatments were applied. Concentrations of dissolved P and total P exceed critical values associated with accelerated eutrophication. No significant differenced were found for sediment P concentrations on either 5 or 10% slopes for any of the three rates of P application. Phosphorus applications did not significantly affect dissolved P concentrations on the 5% slope, but there were significant treatment effects for dissolved P concentrations on the 10% slope. Slope did not significantly affect dissolved P concentration but significantly affected sediment P concentration. Total P mass losses in surface runoff were < 0.6 kg P ha⁻¹ on the 5% slope and 1.0 kg P ha⁻¹ on the 10% slope during the research period." |
