Irrigation system walk-through inspection analysis

Creator:: Hansen, Hugh J., Trimmer, Walter L., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension, and Pacific Northwest Cooperative Extension
Abstract:: This “walk-through” worksheet provides a method for making an organized inspection of an entire irrigation system, both hydraulics and hardware. This inspection will help identify components that need maintenance, repair, replacement, or other attention—so that the system will provide the most satisfactory, safe, and efficient performance.

Vulnerability and adaptation of Pacific Northwest shellfisheries to ocean acidification

Creator:: Katz, Brian G.
Abstract:: The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...

Influence of Soil Texture on Carbon Storage of PNW Coastal Blue Carbon Ecosystems

Creator:: Fox, Conner S.
Abstract:: Coastal blue carbon ecosystems offer a variety of important ecosystem services, including exceptional rates of carbon sequestration and long-term carbon storage. Because these ecosystems disproportionately influence global carbon cycling, understanding their soil characteristics may help guide long-term climate change mitigation and adaptation strategies. Recently, Kauffman et al. (2020) observed the...

Sizing irrigation mainlines and fittings

Creator:: Trimmer, Walter L., Hansen, Hugh J., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension Service, and United States. Department of Agriculture
Abstract:: When designing or retrofitting an irrigation system, one of the key decisions is picking the proper size pipes and fittings for the system. The best pipe size or fitting is not always the one with the lowest initial cost. The important consideration is the lowest cost of ownership. The objective...

Irrigation runoff control strategies

Creator:: Hansen, Hugh J., Trimmer, Walter L., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension Service, United States. Department of Agriculture, and Pacific Northwest Cooperative Extension
Abstract:: More than 4.5 million acres in the Pacific Northwest are irrigated with electric-powered sprinkler systems. Center pivots are used on about 1.25 million acres. Irrigation runoff can be a problem on many of these sprinkler-irrigated fields.

Assessing the Role of Snow Cover for Regenerating Forests over Post-wildfire Landscapes in the Pacific Northwest

Creator:: Wilson, Andy C.
Abstract:: Forested, mountain landscapes in the Pacific Northwest (PNW) are changing at an unprecedented rate, largely due to shifts in the regional climate regime. Documented climatic trends across the PNW include increasing wildfire frequency and intensity and an increasingly ephemeral snowpack, especially at moderate elevations. One relationship that has yet to...

Strategic investments in agricultural industries and Oregon's economic development

Creator:: Koong, Dennis T
Abstract:: This research is concerned with the current debate among Oregonians on how to improve the standard of living and accelerate economic development in Oregon. The main question is what economic activities make Oregon, and regions within Oregon grow? To find out where Oregon's economic strength and weaknesses lie, first we...

Introgression and Evaluation of Wheat (Triticum aestivum L.) Conferring Resistance to Quizalofop-p-ethyl Herbicide

Creator:: Richter, Colette M.
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world supplying about 18.8 percent of the world's caloric energy supply and 20 percent of the world's protein. In the Pacific Northwest (PNW), over one million hectares of wheat are grown every year. Wheat production is typically...

Trait-based approaches to linking vegetation and food webs in early-seral forests of the Pacific Northwest

Creator:: Campbell, John L. and Donato, Daniel C.
Abstract:: Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...

Detection and Quantification of Pratylenchus thornei in DNA Extracted from Soil Using Real-Time PCR

Creator:: Yan, Guiping, Smiley, Richard W., and Okubara, Patricia A.
Abstract:: The root-lesion nematode Pratylenchus (hornet is one of the most important pests restricting productivity of wheat in the Pacific Northwest (PNW). It is laborious and difficult to use microscopy to count and identify the nematodes in soils. A SYBR Green I-based real-time polymerase chain reaction (PCR) assay was developed to...
