Infiltration, soil erosion, nitrogen loss and soil profile characteristics of Oregon lands occupied by three subspecies of Artemisia tridentata

Creator:: Swanson, Sherman R.
Abstract:: Infiltration, soil erosion, nitrogen loss and soil profile characteristics were measured on 36 sites representing land occupied by Artemisia tridentata ssp. tridentate, wyomingensis, and vaseyana. Infiltration, soil erosion, and nitrogen loss were strongly correlated but highly variable. Soil loss, but not infiltration or nitrogen loss was significantly different between subspecies....

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...

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...

Soils of the Oregon coastal fog belt in relation to the proposed "Andisol" order

Creator:: Badayos, Rodrigo Briones
Abstract:: A study was conducted to evaluate the properties of soils in the fog belt area of the Oregon Coast Range. Soils in the study were chosen to include only those belonging to Andepts or to andic subgroups. Samples were collected from eleven sites that were formed mostly from colluvial deposits...

Nature of interlayer material in silicate clays of selected Oregon soils

Creator:: Singleton, P. C.
Abstract:: A study was conducted to investigate the nature of hydroxy interlayers in the chlorite-like intergrade clays of three Oregon soils with respect to kind, amount, stability, and conditions of formation. The clays of the Hembre, Wren, and Lookout soils, selected to represent weathering products originating from basaltic materials under humid,...

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...
