Agronomic biosolids application rates for dryland wheat across a range of northwest climate zones

Creator:: Sullivan, Dan M., Bary, Andrew I., Cogger, Craig G., and Shearin, Todd E.
Abstract:: Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...

Fire ecology of ponderosa pine and the rebuilding of fire-resilient ponderosa pine ecosystems

Creator:: Fitzgerald, Stephen Arthur
Abstract:: The ponderosa pine ecosystem of the West have changed dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a grange of 49-124 trees per ha (20-50...

Curly dock and broadleaf dock, Rumex crispus L. and R. obtusifolius L.

Creator:: Burrill, L. C., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension System, and Pacific Northwest Cooperative Extension
Abstract:: Curly dock (Rumex crispus L.) is a perennial. It does not have creeping roots or rhizomes (Figure 1). Leaves are oblong to nearly lanceshaped, often 12 inches or more long, with wavy (crisped) margins (Figure 2). Erect, generally unbranched stems up to 5 feet tall are produced in spring and...

Identification of Barriers to Industrial Energy Efficiency Improvement in the Pacific Northwest

Creator:: Martz, Allison M.
Abstract:: The US industrial sector accounts for about one-third of the nation’s energy consumption and is predicted to grow twice as quickly as other sectors through 2050. International organizations such as the International Energy Agency project energy efficiency improvements will account for over 40% of greenhouse gas emissions reductions through 2040....

Nuclear and chloroplast diversity of Pacific Northwest wheat (Triticum aestivum) breeding germplasm

Creator:: Edwards, Melanie Love
Abstract:: Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...

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...

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...

Biophysical spectral regionalization of the Pacific Northwest using Advanced Very High Resolution Radiometer Imagery

Creator:: Greninger, Jon F.
Abstract:: Satellite imagery has become an efficient and time effective tool that may aid in the development of regional terrestrial and aquatic resource management schemes. A methodology utilizing National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) imagery, 1.1 kilometer spatial resolution at nadir, was developed for delineating...

Stand conditions associated with tree regeneration in Sierran mixed-conifer forests

Creator:: Gray, Andrew N., Zald, Harold S.J., Kern, Ruth A., and North, Malcolm
Abstract:: Fire suppression has significantly increased canopy cover, litter depth, and stem density in many western forests, altering microsite conditions that affect tree seedling establishment. We conducted studies in a mixed-conifer forest in the Sierra Nevada, California, to determine relationships between established understory trees and microsite quality, and to examine the...

Opportunity costs : irrigation vs. hydropower

Creator:: Ross, Mark
Abstract:: In recent years we have seen increasing debate over the allocation of PNW water resources. In particular there are conflicts over using the river system for irrigation vs. electricity production. Denying the hydroelectric system water implies higher costs to electricity consumers as producers substitute more expensive nonhydro resources. This research...
