Abstract: Many research projects are underway to address agricultural nonpoint source pollution of ground and surface waters. Many of these have the objective to develop and test models to predict the fate and transport of nutrients and pesticides. An extensive data base will be necessary to validate the reliability of the models developed. The experimental methodology for a precisely controlled water table management field experiment being conducted in North Carolina is presented. This field study is instrumented to provide a long term, comprehensive data base for testing predictive methods to quantify the fate and transport of nutrients and pesticides.
