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...

Variations of moisture retention properties and bulk densities of soils between and within soil-mapping units in central Oregon

Creator:: Jibury, Falih Khidir
Abstract:: The objective of this study was to estimate the bulk densities and points on the moisture-tension curves and to determine their associated variances for some of the selected mapping units in Central Oregon. These variances will produce informations concerning the precision of the mean and the optimum sampling schemes, for...

Morphology and genesis of the Condon, Morrow, and Walla Walla series of the Mid-Columbia basin, Oregon

Creator:: Douglass, John Franklin
Resource Type:: Dissertation

Soil moisture storage, distribution, and use by winter wheat in a 250-350 mm precipitation zone of eastern Oregon

Creator:: Henderson, Robert L.
Abstract:: The semi-arid dryland wheat-producing areas of the Pacific Northwest are characterized by cool, moist winters and dry, hot summers. The amount of annual precipitation is generally quite variable and inadequate for annual cropping. Where soil depth is adequate, the predominant loessal soils generally supply sufficient moisture for small grain production...

Soil physical properties and available water capacity of southwest Oregon forest soils

Creator:: Flint, Alan L.
Abstract:: Measurements for water retention calculations and physical characterization were made on skeletal and non-skeletal soils in southwest Oregon. A new bulk density sampler was designed for the physical characterization of the steep, skeletal soils commonly encountered in this area. The new sampler and the techniques required for the measurement and...

Water loss and uptake in clayey subsoil materials

Creator:: Stannard, Davis Robertson
Abstract:: B and C horizon samples from twenty four selected profiles along a north-south transect in the Willamette Valley were examined for possible correlation between shrinkage properties and kind of clay minerals present. Observations of linear shrinkage, weight loss from a condition of maximum plasticity, and changing character of X-ray diffraction...

El control del riego mediante la tension matricial del suelo

Creator:: Shock, Clinton C., Welch, Teresa, Wang, Feng-Xin, Flock, Rebecca, Feibert, Erik Bruno Goncalves, Shock, Cedric A., Pereira, Andre, and Oregon State University. Extension Service
Abstract:: Explica el uso de los sensores matriciales granulares para la medición de la tensión de humedad del suelo. Explica cómo instalar estos sensores y cómo usar los datos registrados para la programación del riego. (Discusses the use of granular matrix sensors (GMS) for monitoring soil moisture content . Explains how...
