Nitrogen Budget Report

The Nitrogen/Nitrate Budget Report (pdf) details work to link public policy and planning with best available science and associated data. The project identifies potential sources of elevated levels of nitrate in drinking water in the Southern Willamette Valley Groundwater Management Area (SWVGWMA). A better understanding of the quantities of nitrogen applications and potential nitrate contributions, provide a tool to help guide future choices in land use management practices.
