Soil Carbon Determination Using Rapid, Inexpensive, Non-destructive Spectroscopic Techniques
New methods are required to rapidly and accurately measure soil C at field- and landscape-scales to improve local, regional, and global soil C stock and flux estimates. This research evaluated visible-near infrared diffuse ...
FATE AND TRANSPORT OF RADIONUCLIDES [U(VI), Sr, Cs] IN VADOSE ZONE SEDIMENTS AT THE HANFORD SITE
Physical and chemical heterogeneities are inherent in subsurface environments due to varying: mineralogy, pore geometry, solution saturation, and solute concentration. The goals of this research were to study the heterogeneities ...
CAPILLARY FORCES ON SEDIMENT PARTICLES: EXPERIMENTAL MEASUREMENTS AND THEORETICAL ESTIMATES
At the Hanford Site, radioactive wastes have been disposed into the subsurface. These radionuclides move with infiltrating water both in solution and via adsorption on mobile colloidal soil particles. Extensive research ...
EVALUATION OF PHOSPHORUS INDICES IN RECENTLY ACIDIFIED SOIL OF THE COLUMBIA BASIN, WASHINGTON STATE
Continual application of ammoniacal sources of nitrogen fertilizer can result in decreased bulk soil pH. Many soils of the Columbia Basin (CB), Washington State are weakly buffered and therefore susceptible to acidification. ...
Rotational Cropping Systems for Nitrogen Management and Weed Control in Dryland Organic Wheat Production
Diversification of cropping systems with legumes is a common practice used to overcome soil fertility and weed control challenges in organic farming systems. The current study assessed different legume-intensive cropping ...
