Creator:: Ndiaye, Evelyne L.
Abstract:: Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...

Creator:: Nelson, Machelle A.
Abstract:: A better understanding of grass seed crop and soil fertility is necessary to improve fertilizer practices and preserving water quality in Willamette Valley, Oregon, where 55% of land-use is in grass seed production that directly impacts adjacent waterways containing native protected fish species. I determined tillage effects on soil N...

Creator:: Clenet, Danielle R.
Abstract:: Reestablishing native perennial vegetation in annual grass-invaded rangelands is critical to restoring ecosystems, especially following wildfires. Controlling invasive annual grasses is essential to increasing revegetation success; however, pre-emergent herbicides used to control annual grasses prohibit immediate seeding due to non-target herbicide damage. Thus, seeding is often delayed one year following...

Creator:: Le, Hang Thi
Abstract:: The first project of this thesis is an in vitro study. This study was performed with 8 hydrocortisone topical products on the market for the purpose of comparing one Tec Lab product, a Corticool gel, to the other seven common products on the market. The permeation of these products was...

Creator:: Schutter, Mary E.
Abstract:: 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...
