On-line to healthy weighs : electronic messages for employed women on maintaining a healthy weight

Creator:: Sullivan, Angelique S.
Abstract:: A nutrition education program for employed women on maintaining a healthy weight was developed and evaluated. Delivery of eight messages (two per week for four weeks) by electronic mail was tested for effectiveness. The subjects were 243 members of the Oregon State University Office and Personnel Association who were randomly...

Connections between science and business to increase environmentally-friendly food production

Creator:: Rieder, Rebekka M.
Abstract:: This study represents an internship, as a requirement of the Professional Science Masters program at Oregon State University, performed with Western Ag Innovations Inc. The study consisted of two aspects -- one business and one science oriented. The two objectives of this internship were to: 1) qualitatively evaluate how two...

Estimating plant-available nitrogen release from manures, composts, and crop residues

Creator:: Gale, Eric S.
Abstract:: In order to properly utilize organic amendments as nitrogen sources, reliable methods to estimate plant-available nitrogen (PAN) are needed. The objectives of this study were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence (FNE) calculations, (2) examine the relationships between the C/N ratio, total...

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Nitrogen mineralization from organic amendments during the second year following application

Creator:: Kusonwiriyawong, Charirat
Abstract:: Estimates of nitrogen (N) available from long-term application of organic amendments are required to balance N inputs with crop N requirements. Two studies were conducted to (1) determine N mineralized from organic amendments (manures and composts) during year 2 after application, and (2) compare plant-available N (PAN) determined via in...

Estimating the dry matter production, nitrogen requirements, and yield of organic farm-grown potatoes

Creator:: McQueen, John Paul Gainer
Abstract:: As part of a participatory research project, where farmers and Oregon State University researchers collaborated, aspects of potato (Solanum tuberosum L.) growing systems were studied. It was determined through conversations with the farmers that quantification of certain growth parameters of potato was lacking, including dry matter accumulation, crop nitrogen (N)...

Classifying Low Streamflow Parameters in Coastal Southeast Alaska Using Game Cameras and Random Forest Models

Creator:: Lanphier, Kari
Abstract:: Southeast Alaska is located on the traditional territory of the Lingít, Haida, and Tsimshian People. It is comprised of the largest temperate rainforest in the world, with subregions receiving over 500 cm of rain annually. Climate change is predicted to alter the region's timing, type, and magnitude of precipitation and...

Cultural controls for suppressing Phytophthora cinnamomi root rot of blueberry

Creator:: Yeo, John R.
Abstract:: Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...

Maturity and stability evaluation of composted yard debris

Creator:: Brewer, Linda J.
Abstract:: Compost maturity is an important determinant of end use for composted municipal yard debris, and generally refers to the effect the compost has on plants. The rate of microbial respiration is an indicator of compost stability. The objectives of this research were to: i) determine whether continuous aeration resulted in...
