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...

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...

Statistical analysis of climatological data to characterize erosion potential : 6. joint precipitation and freezing events in eastern Oregon/Washington

Creator:: Istok, Jonathan D., Brown, Barbara G., Boersma, Larry, Katz, Richard W., and Murphy, Allan H.
Abstract:: When precipitation falls on frozen soil, serious soil loss can occur. In order to assign realistic probabilities to the occurrence of this condition for use in predicting erosion rates over long time periods, a technique for combining characteristics of precipitation and air temperature records is applied to hourly wet season...

Statistical analysis of climatological data to characterize erosion potential : 4. freezing events in eastern Oregon/Washington

Creator:: Brown, Barbara G., Istok, Jonathan D., Katz, Richard W., Murphy, Allan H., and Boersma, Larry
Abstract:: The occurrence of frozen soil has a major effect on runoff and soil loss in the Pacific Northwest. Hence, information regarding the probabilities of occurrence of periods during which the soil may be frozen is necessary in order to adequately forecast long-term erosion rates for this region. In order to...

Statistical analysis of climatological data to characterize erosion potential : 2. precipitation in eastern Oregon/Washington

Creator:: Brown, Barbara G., Istok, Jonathan D., Katz, Richard W., and Murphy, Allan H.
Abstract:: Periods of precipitation with certain combinations of characteristics (e.g., high intensity rainfall on saturated soil) can lead to appreciable soil loss in the Pacific Northwest. In order to assign realistic probabilities to the occurrence of these periods for use in predicting long-term erosion rates, a soil erosion-specific definition of a...

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...

Soils and parent materials of Findley Lake, Snoqualmie National Forest, Washington

Creator:: Bockheim, James G., Ugolini, Fiorenzo C., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Findley Lake watershed is located in the Snoqualmie National Forest and has a surface area of 259 ha (1 Mi²). The lake is at an elevation of 1128 m (3701 ft) but the ridges attain elevations of 1450 m (4750 ft). The Cougar Mountain Formation, consisting of lava flows, conglomerate,...

Soil weathering processes in the Findley Lake watershed

Creator:: Singer, Michael J. (Michael John), 1945-, Ugolini, Fiorenzo C., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: This is the annual report from the investigators responsible for soil characterization at the Findley Lake watershed. Soil characterization is complete for two soils and is in progress on six others. Site preparation for years 3 and 4 is complete except for lysimeter installation.
