Dynamic Optimization of Nitrogen Use When Groundwater Contamination Is Internalized at the Standard in the Long Run

Abstract: An economic relationship between agricultural production and groundwater pollution is established first by analyzing the problem in a dynamic setting. Using experimental data from 1987 to 1990 from three sites, optimal policy rules that would maintain the nitrate contamination level at the 10 mg/l standard over time are determined next. Nitrogen application rates are then determined based on the optimal policy rule and available residual nitrogen in the root-zone layer. It is shown that in the first year one of the sites should be fertilized at a lower-than-profit-maximizing rate while the other two sites should not be fertilized at all.
