Phosphorus availability in biosolids-amended soils

Creator:: Choate, Jeff
Abstract:: Quantifying labile phosphorus (P) pools in biosolids is needed to manage biosolids for both agronomic and environmental purposes. Phosphorus indices originated in an effort to protect surface water quality from-non-point-agricultural P inputs. The objectives of this research were to: (1) evaluate soil test components of the western Oregon P index...

Fertilizing with biosolids

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Sullivan, Dan M. (Dan Matthew), 1954-, Cogger, Craig George, 1950-, Bary, Andy I., and Pacific Northwest Cooperative Extension
Abstract:: Biosolids are a by-product of municipal wastewater treatment. They contain organic matter and nutrients that are beneficial for soil, crop, and livestock productivity. Raw sewage solids must be processed to meet U.S. Environmental Protection Agency (USEPA) standards before they can be called biosolids. This publication focuses on how biosolids can...

Why they volunteer : a study of participants at nature conservancy work parties

Creator:: Hastings, Kevin L.
Abstract:: This thesis examines the motivations of ecological restoration volunteers with the Oregon chapter of The Nature Conservancy. This study helps fill in voids left by a lack of research on the motivations of ecological restoration volunteers. Studies that have explored restoration volunteer motivation relied largely on surveys that revealed altruistic...

Toward end-user debugging of machine-learned programs

Creator:: Kulesza, Todd
Abstract:: The results of a machine learning from user behavior can be thought of as a program, and like all programs, it may need to be debugged. Providing ways for the user to debug it matters because without the ability to fix errors, users may find that the learned program’s errors...

Food insecurity and hunger in Oregon: a new look

Creator:: Edwards, Mark and Weber, Bruce
Abstract:: Oregon has had the highest hunger rate among all U.S. states for four of the last five years. In this report, we re-examine the data on which these rankings were computed and explore how Oregon’s food insecurity and hunger rates vary across demographic groups.

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Temporal and spatial variability of groundwater nitrate in the southern Willamette Valley of Oregon

Creator:: Mutti, Jeffrey Glenn
Abstract:: Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...

Negotiating purpose : Oregon's gleaning organizations and their roles in relieving hunger and poverty

Creator:: Drage, Kimberly T.
Abstract:: For over 25 years organized groups of low-income families in Oregon have been gathering food that would otherwise go to waste and distributing this food among organization members. The purpose of this research study is to explore the potential for these organizations (gleaning groups) to contribute not only to food...
