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 ...
Impacts of nitrogen fertility, soilborne disease, and socioeconomic factors on diverse small grain production systems of the Pacific Northwest
Small grains are grown in rotation with many temperate crops in the Columbia Basin and Puget Sound regions, functioning to improve the profitability of the cash crops. During 2009-10, 45 isolates of
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 ...
UNDERSTANDING AND CHARACTERIZING THE GENES ASSOCIATED WITH RPG1-MEDIATED RESISTANCE PATHWAY AGAINST STEM RUST
Barley stem rust resistance gene, Rpg1 (Reaction to Puccinia graminis 1), confers durable resistance to barley cultivars against stem rust caused by many races of Puccinia graminis f. sp. tritici. The current study was ...
EFFECTS OF GENOTYPE, FERTILIZER, AND MYCORRHIZAL FUNGI ON PHOSPHORUS USE EFFICIENCY OF ORGANIC AND CONVENTIONAL SPRING WHEAT
Recent attention to the increasing environmental and monetary costs of mining dwindling phosphorus (P) reserves have lead to renewed efforts to design agricultural systems that use P more efficiently. The objective of these ...
Statistical Applications in Plant Breeding and Genetics
Statistical analysis has many applications ensuring the validity and reproducibility of plant breeding and genetics research. Crop plant germplasm collections are often too large to be of use regularly. A core subset with ...
IMPROVING BAKING QUALITY AND LOCAL MARKETS FOR WHEAT GROWN IN WESTERN WASHINGTON
Winter wheat (Triticum aestivum) is currently grown in crop rotations in western Washington to break disease cycles and improve soil quality. There is interest in creating a local grain system to add value to the crop. Two ...
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 ...
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. ...
