leaching periods in winter. Four winter cover crops were grown in western Oregon during a 5-yr field
Assessment of variability and monitoring methods for leaching under cover crop management

Creator:

Hess, Mario

Abstract:

The contamination of ground water resources represents a serious problem and a prominent threat to the health of our society. This study focuses on the leaching of inorganic anions as a function of agricultural practices under natural field conditions. In order to enhance the understanding of such leaching processes, this...

Methods for Leaching Under Cover Crop Management by Mario Hess A THESIS submitted to Oregon
An eleven year study of nitrate leaching in vegetable production with winter cover crops

Creator:

Feaga, Jeff

Abstract:

The Willamette Valley of Oregon has high rates of winter precipitation that cause leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots planted in summer vegetables with and without winter cover...

Flow-Solute : A Tool for Exploring the Effects of Nitrogen Management in Alternative Future Scenarios

Creator:

Wentworth, Andrew Michael

Abstract:

Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...
