The Oregon Long-Term Soil Quality Project was initiated to identify soil
properties that respond rapidly to alternative management practices. Such practices
included winter cover cropping, which was implemented at two experimental research
stations and several grower fields throughout the Willamette Valley. The goal of this
thesis was to identify the...
Forest harvest can have significant impacts on forest ecosystems that may influence the capacity of soils to sequester carbon (C). The microbial community controls decomposition, which is a critical process in partitioning litter- and root-C between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study were to...
Legislation to reduce the annual limit of field burning in Oregon has led to increased study of
alternative non-thermal grass-seed management methods. Of these methods, non-thermal residue
management, in combination with crop rotations and different tillage practices, offer potential to
equal or exceed crop production of conventional thermal production systems....
Intercollegiate wrestling at Oregon State University had its
inception on March 20, 1909. On that day, the Oregon Agricultural
College wrestling team wrestled in a home meet against the team
from Washington State College. The Beavers, under the tutelage of
their first coach Eddie O'Connell, won their first intercollegiate meet,...
There are generally two types of multiview video:(1) 3D Multiview Video (“3D MVV” also called “2D plus delta” or “stereo” multi-view video): 3D MVV is widely deployed in cinemas and in the TV industry. 3D MVV typically entails capturing video of an object using two cameras with differing view angles...
The objectives of this study were: 1) to learn the life history and habits of Medetera aldrichii Wheeler and a Lonchaea sp. in association with the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, in western Oregon and Washington; 2) to determine if the larvae of M. aldrichii were predaceous on the Douglas-fir...
This study was conducted to compare the effectiveness of four
methods of incorporating the herbicide trifluralin into the soil, and
to determine the interaction between depth of incorporation of trifluralin
and depth of weed seed germination.
Field experiments on green and dry peas were established in
Oregon and Idaho. Trifluralin,...
Heterostylum robustum (Osten Sacken) is the principal parasite
of the alkali bee, Nomia melanderi Ckll., one of the most efficient
pollinators of alfalfa in the western United States.
The purpose of the study was to determine the incidence of
parasitism and to investigate the biology of H. robustum.
The fly...
