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...

Development of predictive mapping techniques for soil survey and salinity mapping

Creator:: Elnaggar, Abdelhamid A.
Abstract:: Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...

Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

Creator:: Perez-Jones, Alejandro
Abstract:: A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

Potential impacts of canola (Brassica napus L.) on vegetable seed production in the Willamette Valley of Oregon

Creator:: Quinn, Michael P.
Abstract:: In the Willamette Valley of Oregon, a combination of the need for rotational crops and an increased desire for biofuel production created interest in planting Brassica napus (canola). However, questions were raised arisen over the potential damage canola production could have on the preexisting Brassica vegetable seed industry. To address...

DNA fingerprinting and genome mapping in meadowfoam

Creator:: Katengam, Sureeporn
Abstract:: Marker information in the new oilseed crop, meadowfoam, is limited. Molecular markers to facilitate meadowfoam breeding and cultivar improvement are not available. The knowledge of genetic relationships among recent germplasm is not known. The objectives of this study were (i) to gain an understanding of genetic diversity and relationship patterns...

FR‐H3 : a new QTL to assist in the development of fall-sown barley with superior low temperature tolerance

Creator:: Fisk, Scott P.
Abstract:: Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...

Measuring Electron Activity to Constrain the Role of Soil Structure in the Formation of Biogeochemical Heterogeneity

Creator:: Wanzek, Thomas
Abstract:: Soils have a critical role in global carbon (C) cycling, containing one of the largest fast-cycling carbon stocks on earth. Robust representation of soil organic matter dynamics in Earth System Models is critical for future climate prediction. Current C cycling models assume that all C cycling in non-hydric (i.e. ‘upland’)...
