Hydrologic properties of soil and subsoil on a steep, forested slope

Creator:: Ranken, Darrel Wesley
Abstract:: The purpose of this study was to examine certain hydrologic properties of the soil and subsoil on a steep forested slope and relate these -rceTties to the movement of water via subsurface routes. The hydrologic properties examined were bulk density, soil texture, total porosity, pore size distribution, saturated hydraulic conductivity,...

Soils of the reference stands -- Oregon IBP

Creator:: Brown, R. B. (Randall Barber), Parsons, Roger Bruce, 1932-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Field reconnaissance, soil sampling, and laboratory analyses were conducted to characterize the soils of the 50 by 50 meter forest community reference stand plots in and near the H. J. Andrews Experimental Forest. Soil descriptions, chemical and physical properties, soil classification, and nutrient capital information for mineral soils are summarized....

Soil compaction from low ground-pressure, torsion-suspension logging vehicles on three forest soils

Creator:: Froehlich, Henry A. and Oregon State University. Forest Research Laboratory
Abstract:: Monitoring soil density on three sites during repeated trips with a high-speed skidder showed that: During the first 20 trips, soil density primarily increased between depths of 2 to 4 inches; Density increased most during the first few trips; Density continued to increase slowly in amount and depth with the...

Soil variability, Oregon IBP: Annual report 1972

Creator:: Brown, R. B. (Randall Barber), Parsons, Roger Bruce, 1932-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Goals in 1972 included characterization of the soils of the Oregon IBP reference stands, development of information on the soils throughout the H. J. Andrews Experimental Forest, and evaluation of nutrient provision to the major kinds of soils. Field reconnaissance, soil morphology studies, and sampling were carried out. Lab analyses...

Movement of water through forested soils in steep topography

Creator:: Harr, R. Dennis (Robert Dennis), 1941-, Ranken, Darren W., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Field and laboratory studies are being conducted to describe the hydrologic properties of soil and to determine the timing pathway of precipitation and snowmelt water as it moved through forested soil on a steep slope. Hydrologic properties include hydraulic conductivity, porosity, pore-size distribution, moisture characteristics, stone content, and soil depth....

Findley Lake soil temperature and soil moisture data, August 1972 - August 1973

Creator:: Singer, Michael J. (Michael John), 1945-, Ugolini, Fiorenzo C., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Data on soil temperature at two locations and five depths, tensiometer readings, and soil moisture release curves for the soils of Findley Lake are presented in this report.

Variation in air and soil temperatures in forest communities on the H. J. Andrews Experimental Forest, 1970-1972

Creator:: Zobel, Donald B., McKee, Arthur, Hawk, Glenn M., Dyrness, C. T., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Air temperatures at i m and soil temperatures at 2C cm are reported for twenty-one forest stands in the central Western Cascader of Oregon. Records began in 1970 for some stands, in 1971 or 1972 for most. Temperature Growth Index for a stand, based on temperature effects on Douglas-fir seedling...
