Abstract/Contents: | "Pastured watersheds on hill slopes in eastern ohio were fertilized with ammonium nitrate (NH4NO3) at two different levels for 5 years. The pastures were rotationally grazed during either the growing season (May-October) or the dormat season (November-April). Nitrate-N concentrations were measured in surface runoff events > 0.1 mm from nine watersheds. During the 5-year period, there were 890 runoff events. Sixty-four of these events (7%) had NO3--N, concentrations > 10 mg/L, and 48 of the 64 events occured within a 30-d period following fertilizer application. Ten events, < 2% of all of the runoff events, exceeded 30 mg/L NO3--N, and all of these were within 17 d of fertilization. Although all surface runoff events which closely followed fertilizer applications did not have high NO3--N concentrations, all surface runoff with high NO3--N was shortly preceded with a fertilizer application. The closeness of the high NO3-N concentration and fertilizations suggested that fertilizer was the major contributor to high NO3--N in runoff as opposed to animal waste." |
