Abstract: Nonpoint Source Pollution (NPS) from agriculture has been recognized as the major problem affecting water quality across the nation for some time. W hile NPS is not the acute problem that industrial point sources or toxic waste sites can be, NPS is problematic because it is so pervasive. It is the result of our daily actions, our daily management of the land around us. While the environmental impacts of individual actions may hardly be noticeable, the cumulative effects may be great, particularly with their persistence over time. Most of us in agriculture have learned these princip les in relation to soil erosion over the past 50 years. Over the past few decades we have also come to realize that our increased use of nutrients, pesticides, and other inputs have resulted in similar cumulative impacts on the environment (e.g., Hallberg 1989 a, b).
