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...

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...
