Geostatistical applications to salinity mapping and simulated reclamation

Creator:: Al-Taher, Mohamad A.
Abstract:: Geostatistical methods were used to find efficient and accurate means for salinity assessment using regionalized random variables and limited sampling. The random variables selected, sodium absorption ratio (SAR), electrical conductivity (EC), and clay content were measured on samples taken over an area of fifteen square miles. Ordinary kriging and co-kriging...

Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Functional profiles of soil microbial communities in second-growth Douglas-fir forests of the Pacific Northwest

Creator:: McGinnis, Megan L.
Abstract:: Forests are one of the largest repositories of terrestrial C. Understanding factors that drive organic matter transformations and nutrient efflux from these systems is therefore highly important. Temperate forests are of particular significance due to the large fraction of C that is stored below ground in the soil. Characterizing nutrient...

The influence of phosphatase-producing bacteria on phosphatase activity and available phosphorus in soil

Creator:: Nelson, Sheila J.
Resource Type:: Masters Thesis

The Biology and ecology of weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana)

Creator:: Tarasoff, Catherine
Abstract:: Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...

Potential Heterotic Groups in Hop as Determined by AFLP Analysis

Creator:: Townsend, M. Shaun and Henning, John A.
Abstract:: Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...

Use of Pyrosequencing Technology to Genotype Imidazolinone-Tolerant Wheat

Creator:: Ellison, Mackenzie T., Fischinger, Frank, Zemetra, Robert S., and Kuhl, Joseph C.
Abstract:: Cultivars of several cereal crops have been developed with acetohydroxyacid synthase (AHAS) insensitivity to imidazolinone herbicides and are now an important tool for weed management. Options for screening for imidazolinone resistant lines include direct herbicide application, biochemical assays for AHAS activity and DNA-based methods. Herbicide and biochemical assays for AHAS...

Hydric Soils in Eastern Oregon Temporary Pools

Creator:: Clausnitzer, David
Abstract:: Two types of temporary poois, known as playas, occur in semiarid southeast Oregon. Vegetated upland playas are found in the High Lava Plain province; barren alkaline-saline playas are found in the Basin and Range province. Both types become ponded in most years, but they often lack redoximorphic features indicative of...
