Effects of Initial Moisture and Surface Properties on Sorptivity of Coarse Soil and Sand

Creator:

Ambrowiak, Gloria M.

Abstract:

Many different models and mechanisms of water imbibition into soil have been described in the literature. Theoretical equations based on those models exist to predict how water will flow in porous media. These models can be useful, but have their weaknesses. Research on imbibition and infiltration into soils has mostly...

Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:

Woolverton, Priscilla B.

Abstract:

This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...

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...
