Interpretive Summary:

Technical Abstract: A rainfall simulator was used to apply 2-hour, 5-cm rains to each of two 624m2 corn plots at six times during the growing season in each of two years, ranging from at-planting to mature canopy. Fertilizer, incorporated nematicide, herbicide, and foliar insecticide and fungicide applications were followed closely by artificial rainfall and the resulting runoff water rwas measured and analyzed for nutrients, sediment, metals and pesticides and metabolites. Weather, soil moisture conditions, leaching and crop growth were monitored and soil characteristics were determined in detail. The resulting highly replicated and reproducible data set should provide a scenario for detailed evaluation of field-scale nonpoint pollution prediction models. The data set is being mounted on an internet site and will be documented in detail.
