Non-point agricultural contaminants, such as nitrogen, may lower groundwater quality and thereby impose health and environmental risks. The objective of this study is to evaluate tax policies to control agricultural pollutants in a spatially heterogeneous and dynamic setting. The focus of the study is non-point source nitrate contamination of groundwater...

Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...
To better understand the impact of land use on stream nutrient export, a synoptic sampling of 57 sub-basins within the Willamette River basin was conducted during winter baseflow conditions (February 2009). I assessed whether stream dissolved organic carbon (DOC), NO₃⁻ and Cl⁻ and specific ultra-violet absorbance (SUVA) values were correlated...
This research is concerned with the current debate among Oregonians on how to improve the standard of living and accelerate economic development in Oregon.
