Abstract/Contents: | "Simulated rainfall was used to evaluate the effectiveness of vegetative filter strip(VFS) of varying lengths (0, 3, 6 9, 15 and 21 m) in reducing sediment and nutrient losses from plots treated with liquid swine manure at 200 kg Nl ha. Mass transport of ammonia nitrogen (NH₃₋N), total Kjeldahl nitrogen (TKN), ortho-phosphorus (PO₄₋P), total phosphorus (TP), and total suspended solids (TSS) was reduced significantly (p< 0.05) by fescue (Fescue arundinacea Schreb.) VFS. The 3 and 21 m VFS removed 65 and 87% of incoming TKN, 71 and 99% of incoming NH₃₋N, 65 and 94% of incoming PO₄₋P, and 67 and 94% of incoming TP, respectively. Effectiveness of VFS, however, did not increase significantly beyond 3m for TSS and chemical oxygen demand and averaged 61 and 50%, respectively. Mass transport of TKN, NH₃₋N, PO₄₋P, amd TP was minimized at the 9 m VFS length. The VFS did not significantly reduce nitrate nitrogen and fecal coliform from the incoming runoff. First-order kinetics described the removal of manure constituents." |
