Acidifying soil for crop production west of the Cascade Mountains

Creator:: Oregon State University. Extension Service, Horneck, Donald Arthur, Hart, John M. (John Mervyn), 1947-, Stevens, R., Petrie, S., and Altland, James Elmer, 1973-
Abstract:: Soil acidification sometimes is necessary for optimum plant growth west of the Cascade Mountain Range. Commercial producers of blueberries, azaleas, rhododendrons, and other ornamentals may need to reduce soil pH for optimum production. Soil acidification is best performed prior to planting; it is much more difficult in established plantings. No...

Microbiology of basalts targeted for deep geological carbon sequestration : field observations and laboratory experiments

Creator:: Lavalleur, Heather J.
Abstract:: With rising concentrations of CO₂ in the Earth's atmosphere causing concern about climate change, many solutions are being presented to decrease emissions. One of the proposed solutions is to sequester excess CO₂ in geological formations such as basalt. The deep subsurface is known to harbor much of the microbial biomass...

Acidifying soil for blueberries and ornamental plants in the yard and garden west of the Cascade Mountain Range in Oregon and Washington

Creator:: Oregon State University. Extension Service, Hart, John M. (John Mervyn), 1947-, Horneck, D., Stevens, R., Bell, Neil (Neil Charles), 1961-, and Cogger, Craig George, 1950-
Abstract:: Rhododendrons and blueberries are popular plants in home gardens in western Oregon and Washington. Both are easy to grow in most gardens, but problems with growth can occur if the soil is not sufficiently acidic. Even in the naturally acidic soil west of the Cascade Mountains, soil often is not...

Soil carbon and nitrogen in old-growth forests in western Oregon and Washington

Creator:: Remillard, Suzanne Marie
Abstract:: Soil organic carbon (SOC, kg C m-2) is an important component in evaluating global C stores. The nitrogen (TN, kg N m"2) cycle is closely linked to C and understanding its role is also important. Contents and distributions of SOC and TN in soil profiles, to 1-meter depth, were estimated...

Microbial community structure as influenced by season and stand age in a Douglas-fir (Pseudotsuga menziesii) ecosystem

Creator:: Kucera, Jennifer Moore
Abstract:: Forest harvest can have significant impacts on forest ecosystems that may influence the capacity of soils to sequester carbon (C). The microbial community controls decomposition, which is a critical process in partitioning litter- and root-C between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study were to...

Physiochemical mechanisms for the transport and retention of technetium

Creator:: Jansik, Danielle P.
Abstract:: Understanding the transport and retention of radionuclides in the environment is important for protecting freshwater supplies and minimizing impact to biologic systems. Technetium-99 (Tc⁹⁹) is a radionuclide of interest due to its long half-life (2.13 x 10⁵ years) and toxicity. In the form of pertechnetate (TcO₄⁻), Tc is expected to...

Estimating plant-available nitrogen from manure

Creator:: Oregon State University. Extension Service and Sullivan, Dan M. (Dan Matthew), 1954-
Abstract:: Nutrient management plans for crops require estimates of plant-available nitrogen (PAN) provided by application of manure or compost. Recent developments have stimulated interest in utilizing manure nitrogen (N) as a resource. These factors include the following: • Increased cost of N fertilizers • Increased value of PAN from manure on...

Aboveground vegetation and viable seed bank of a dry mixed-conifer forest at a wildland-urban interface in Washington state

Creator:: Snider, Gabrielle
Abstract:: Dry coniferous forests in the western United States are experiencing severe wildfires, insect outbreaks, forest disease epidemics and a growing presence of invasive species. Policies strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI) where communities and forests intersect. However, these areas present restoration challenges as they tend...

Characterization of Vibrio parahaemolyticus isolated from Oregon and Washington coastal water and development of improved methods for Vibrio parahaemolyticus detection

Creator:: Duan, Jingyun
Abstract:: Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....

Establishment of concentration ratios for riparian and shrub steppe areas of the eastern Washington Columbia basin

Creator:: Napier, Jonathan Bamberger
Abstract:: Concentration ratios are used to determine the transfer of nuclides from soil to biota to fauna. Some nuclides have limited associated data though, this has not prevented predictions from being performed at sites without associated data. These ratios are site specific and are not fully applicable when applied to other...
