The Willamette Valley of Oregon has high rates of winter precipitation that cause leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots planted in summer vegetables with and without winter cover...
Corylus avellana L. is a global commodity and a valuable crop for the U.S. Pacific Northwest. A tremendous amount of work has been put into the development of healthy disease free, high yielding and tasty hazelnuts for the in-shell and confectionary markets. Clonal propagation is required to provide nursery trees...
Freshwater wetlands in the Sacramento Valley provide breeding, wintering, foraging and stopover habitat for migratory and resident birds. With a loss of 95% of historic freshwater wetlands, the restoration of wetlands on private land could provide important habitat for birds. Documentation and monitoring of bird use on previously restored wetlands...
The objective of this study was to develop a decision making tool to determine economic feasibility of artisan cheese operations. A survey of current Oregon artisan cheese companies was used to gain knowledge of the fixed and variable costs associated with cheese production and business start-up. The data from this...
Staling in beer is inevitable. Oxidation and increased temperatures are the main causes of stale flavors in bottled beers. Since 1934, research has been done to identify compounds and pathways involved in creating stale flavors. Although many research papers report stale flavors, there is not a lexicon per se of...
Water use restrictions are continuing to have an impact on the way turf is managed today and will be managed in the future. The objective of this research was to evaluate the irrigation requirements of ten newly established cool-season turfgrass species maintained under two different mowing height and nitrogen fertility...
In order to properly utilize organic amendments as nitrogen sources, reliable methods
to estimate plant-available nitrogen (PAN) are needed. The objectives of this study
were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence
(FNE) calculations, (2) examine the relationships between the C/N ratio, total...
The relative success of restoration practices on cheatgrass infested sagebrush steppe lands in the Great Basin can affect the probability of crossing an ecological threshold and have economic effects on cattle ranches using federal rangelands. Cheatgrass invasion implies an increase in the risk of fire, which in turn increases the...
Two experiments were conducted looking at both acute and sub-acute laminitis. An acute nutritional induction model was used to examine whether blood profiles and gene expression are similar to other studies conducted using an endotoxin induction model. Twelve sheep were randomly assigned to three treatment groups which were control, 4-hour...
Blackberries, genus Rubus, are an important Oregon agricultural commodity. In their fresh and processed forms, they offer many health benefits and may be able to help Americans better achieve fruit consumption recommendations because of convenience and pleasant sensory qualities. However, the susceptibility of blackberry products to contamination with bacterial pathogens...
