Abstract
Data on the field-to-stream transport of sediment and chemicals from an agricultural watershed were collected in a 3-year study to provide information for testing and evaluating mathematical models under development for predicting agricultural nonpoint source pollution. These models are prepared as tools to evaluate the effectiveness of different farm management practices in controlling losses of nutrients, pesticides, and sediment in field drainage to receiving waters. In the study, data were collected for small corn, soybean, and pasture fields; for two larger mixed-cover watersheds; and at three drainage-stream sites.
