Groundwater and nitrogen management in Willamette Valley mint production

Creator:: Oregon State University. Extension Service, Selker, John, and Rupp, David Earl
Abstract:: Directly below commercial mint fields, percolation in excess of 10 ppm of nitrogen as nitrate (NO3 --N), the EPA drinking water standard, occurs for much of the year (Figure 1, page 2). Concentrations rise rapidly after irrigation starts in June, indicating that this nitrogen is being pushed through by irrigation...

The effect of nitrogen, irrigation, and cultivation on Pinot noir juice and wine composition from the Willamette Valley, Oregon

Creator:: Wall, Katherine Elizabeth
Abstract:: This study investigated how manipulating vineyard nitrogen status, irrigation levels and cultivation practices would effect nutrient composition, and anthocyanin and phenolic accumulation in Pinot noir juice and wine from a commercial Willamette Valley Oregon vineyard. Pinot noir fruit was sourced from a vineyard trial in the Benton Lane Vineyard, located...

Field measurements of nitrate leaching below Willamette Valley row and mint crops

Creator:: Oregon State University. Extension Service, Feaga, Jeff, and Selker, John S.
Abstract:: According to the United States Geological Survey, 9 percent of wells in the Willamette Valley exceed the EPA’s 10 ppm drinking water standard for nitrogen in the NO3– compound, or NO3–-N. A study of 281 domestic drinking water wells in Lane County showed that 22 percent of the wells exceeded...

Conserving avian diversity in agricultural systems : the role of isolated Oregon white oak legacy trees

Creator:: DeMars, Craig A.
Abstract:: Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...

Private forests, public policy : oak conservation on family forests in Oregon’s Willamette Valley

Creator:: Fischer, Alexandra Paige
Abstract:: In the United States, many of the thorniest natural resource conflicts occur on private lands. This is especially true in the Willamette Valley of Western Oregon where the hallmark habitat type, Oregon white oak woodland and savanna, is imperiled. Almost exclusively found on private land, Oregon white oak is threatened...

An eleven year study of nitrate leaching in vegetable production with winter cover crops

Creator:: Feaga, Jeff
Abstract:: The Willamette Valley of Oregon has high rates of winter precipitation that cause leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots planted in summer vegetables with and without winter cover...

Pollination and pollinators of pumpkin and squash (Cucurbita maxima Duchesne) grown for seed production in the Willamette Valley of western Oregon

Creator:: Gavilánez-Slone, Jenny M.
Abstract:: 'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...

Effect of soil moisture manipulation and nitrogen application on leaf gas exchange, fruit composition, and carbohydrate storage of Pinot noir and Chardonnay grapevines in the Willamette Valley

Creator:: Howe, Jessica
Abstract:: This study integrates various vineyard practices that may improve nitrogen availability to the vine, particularly during ripening. Different strategies aimed at increasing yeast assimilable nitrogen in the fruit at harvest have been evaluated. This study seeks to improve fermentation behavior and wine quality through vineyard practices used for nitrogen management....

Effect of crop level on yield components, fruit and wine composition, and wood carbohydrate reserves of Pinot noir grapes

Creator:: Brasher, Erik W.
Abstract:: Crop thinning trials were studied during two seasons at two locations in the northern Willamette Valley of Oregon. At Willakenzie Estate (site #1), research vines were Pinot noir clone Dijon 113 on 3309 rootstocks trained to a double Guyot. Vines were established in 1996 at a spacing of 2.5 x...
