Abstract or Summary
  • Prevention of groundwater contamination by agricultural chemicals requires an understanding of the complex processes that control pesticide movement below the soil surface. Through this understanding it is possible to try to predict which areas may be most vulnerable to contamination. The many models that have been developed to characterize pesticide movement vary widely in their conceptual approach and degree of complexity. A soil properties model was developed in this thesis to determine the relative overall pesticide movement potential in Oregon agricultural soils. Its focus is ease of use in both acquisition of input values and running of the model. The model is based on soil properties important in controlling pesticide movement. It is a rating system model that uses scoring of factors and matrices to weigh the soil values. It is organized into two processes: leaching and sorption. The leaching potential is based on soil permeability and drainage class. The sorption potential is based on organic matter content and texture of the soil surface horizon(s). The interaction of these two processes results in the overall pesticide movement potential.
