Abstract
Long-term CREAMS and GLEAMS model simulations were used to assess significant differences in potential pesticide and nitrate movement to groundwater as affected by several combinations of tillage, cropping, and nutrient and pesticide management practices. The study area is in Richmond County in the Coastal Plain region of Virginia. Alternative management scenarios were based on crop management systems common to the area. Average annual loads from 35-year simulations were used in the analysis. Friedman's distribution-free analysis of variance and sign tests were found to be appropriate statistical procedures to assess significant differences between effects of management practices.
