This ethnographic study examined some of the ways that global markets and the infrastructure of agribusiness affect local smallholder farmers in the Ten Rivers region who are transitioning toward more sustainable and traditional agricultural methods. The purpose of this research was to discover what barriers smallholder farmers face in developing...
The study was conducted in an organic trailing blackberry (Rubus L. subgenus Rubus, Watson) planting established at the North Willamette Research and Extension Center in Aurora, OR on 26 May 2010. Three weed management systems were compared for 'Marion' and 'Black Diamond': 1) non-weeded; 2) hand-hoed two to three times...
There is limited information available on production of trailing blackberry, particularly certified organic plantings, which are of interest to growers as there is increased consumer demand and a price premium over conventionally-produced fruit. Various production strategies were evaluated for their effect on yield, biomass production, carbon (C), and nutrient concentrations...
High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...

Sensory properties of four important volatile sulfur compounds, dimethyl disulfide (DMDS), diethyl disulfide (DEDS), methanethiol (MeSH) and ethanethiol (EtSH), were determined in base Oregon Pinot noir wine in order to understand their impacts on wine aroma. Detection thresholds of these four compounds in base wine were determined first. All four...
The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...
For oysters, "The objective of these studies was to determine the biological feasibility of using the heated effluent from coastal nuclear power plants for culturing the Pacific oyster, Crassostrea gigas." (p.1) Work included oyster growth experiments, seasonal growth experiments and closed system studies. For salmon, "The objective of these studies...
