Nitrate and water under terraced dryland wheat production in Oregon

Creator:

Strock, Jeffrey S.

Abstract:

Dry land agriculture using summer fallow is a common crop production practice in the Columbia Plateau region of eastern Oregon. Farmed-over level terraces are used to control surface water runoff and soil erosion. More than 70 percent of the average annual precipitation around Pendleton, Oregon (350 - 400 mm) falls...

Quantification of the nitrate attenuation capacity of low-permeability Missoula Flood deposits in the Willamette Valley of Oregon

Creator:

Arighi, Louis M.

Abstract:

Low-permeability geologic units may offer significant chemical and hydraulic protection of adjacent aquifers, and are important for managing groundwater quality, especially in areas with significant non-point source contamination. Nitrate in the Willamette Valley is attenuated across the Willamette Silt, a semi-confining unit overlying a regionally important aquifer. To quantify the...
