Cation retention and solute transport related to porosity of pumiceous soils

Creator:: Doak, William Herman, 1941-
Abstract:: Previous studies of pumiceous soils in Oregon indicated that their physical and chemical properties were strongly related to the porous nature of the pumice matrix. Soils developed on air-fall pumice from the eruption of Mt. Mazama (Crater Lake, Oregon) had low thermal conductivities and low volumetric heat capacities. Values for...

Ion uptake by wheat (Triticum aestivum VILL., Host) as a function of soil water suction and soil temperature

Creator:: Young, Richard Su-Shung
Abstract:: The effects of soil temperature and soil water suction on the uptake of calcium, magnesium, and potassium by wheat (Triticum aestivum VILL., Host) were studied. Companion studies on uptake of nitrogen and phosphorus provided background for discussion of the results. Plants were grown in perlite slabs separated from an osmotic...

Experimental analysis of subsurface heating and irrigation on the temperature and water content of soils

Creator:: Sepaskhah, Ali Reza
Abstract:: Multiple use of waste heat from power plants may become an important consideration in the development, siting, and certification of these plants. A multiple use system of components that can beneficially utilize waste heat may include home heating and cooling, greenhouses, animal enclosures, open basins for single cell protein production...

Water and anion movement in selected soils of western Oregon

Creator:: Hammermeister, Dale P.
Abstract:: Experiments were carried out to study the movement of water and halide anions in perched water tables or saturated zones in the soil and upper rock mantle of eight different experimental sites located on low hills near the western border of the Willamette Valley. At each site the experimental procedure...

Distribution, form, and signigicance of plant opal in Oregon soils

Creator:: Norgren, Joel A.
Abstract:: This study was undertaken to increase knowledge of opal phytoliths in plants and soils of Oregon, and thus encourage further use of phytoliths in future pedologic investigations. Content of plant opal in needles from ten common Oregon conifer species ranged from 0.2 to 7.9%. Western larch (Larix occidentalis) contained the...

Extractable forms of Al and Fe in acid Western Oregon soils

Creator:: Spycher, Gody
Abstract:: Extractable forms of Al and Fe were studied in five soils from the Coast Range, and in two soils from the Willamette Valley in Oregon. Exchangeable Al was determined in a way which permitted a comparison of three different methods for its determination. Values for exchangeable Al obtained by the...

Mineralogical and chemical characteristics of western Oregon Andic soils

Creator:: Franklin, William Talbert
Abstract:: A study was conducted to determine the mineralogy and chemical properties of "Ando-like" western Oregon soils. The samples were collected from 13 sites which formed mainly from basaltic rocks, a contact metamorphic rock, sedimentary rocks, and alluvium derived from sedimentary rock and from volcanic rock. All samples contained small amounts...

Soil moisture and temperature relationships under fallow in eastern Oregon

Creator:: Russelle, Michael P.
Abstract:: Time of stand establishment is a critical factor affecting yields of winter wheat and barley in the fallow-crop rotation areas of the Pacific Northwest. Farmers in this winter-rainfall region are dependent on residual moisture in the seed zone for germination, because significant precipitation does not usually occur until after the...
