Interpretive Summary:

Technical Abstract: Grass hedges may reduce runoff losses of nutrient and sediment and lessen surface water pollution. The objective of this study was to evaluate the effects of a grass hedge (0.75 m wide) on transport of P, N, and sediment from a field receiving manure. No-till and disked systems were the main plots and subplots consisted of application of manure, fertilizer and check kwith or without a grass hedge. A rainfall simulator was used and runoff wa collected from both the initial and wet runs. There was no effect of tillage on runoff concentration of dissolved P (DP), bioavailable P (BAP), total P, or NO3-N during both runs. Grass hedge reduced runoff DP and BAP from manure application during the wet run by 48% each in the no-till and by 13% and 25% in the tilled plots, respectively. Grass hedge reduced runoff NO3-N concentration from manured plots by 28%. Grass hedges were effective in reducing sediment, P, and NO3-N losses in runoff.
