Uncertainty in neutron probe measurements of soil moisture for irrigation scheduling

Creator:: Wright, Norman D.
Abstract:: Soil moisture in a crop's root zone must be regularly monitored to accurately predict crop water requirements. Most irrigation scheduling services currently use the neutron probe to monitor soil moisture. Unfortunately, there is a degree of variability associated with use of the neutron probe creating uncertainty in measurements of soil...

Leaf stress in corn, beans, and tomatoes under optimum soil moisture conditions

Creator:: Nilsson, Colin Wayne
Abstract:: Under adverse soil moisture conditions a critical water stress or water potential develops in the plant and productivity is reduced, or in extreme cases, terminated. Research to determine the soil moisture status for maximum production of specific crops has been conducted for decades. The results have done much to increase...

Automated water balance procedure for large-scale experimental databases based on soil moisture

Creator:: Grayson, Susana Maria
Abstract:: Based on the determination of the zero-flux plane, a water balance procedure for large-scale experimental databases was automated to estimate the soil water balance based on soil water content distribution with depth through time. The automated procedure was verified using data from the BOREAS project obtained in three Intensive Field...

Effects of water stress on phenology, physiology, and morphology of containerized Douglas-fir (Psuedotsuga menziesii (mirb.) Franco) seedlings

Creator:: Khan, Shafiqur Rehman
Abstract:: Approximately 3-4 month-old containerized Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings (seed zone 262 and 271) were subjected to 6 moisture stress treatments (65, 53, 41, 29, 17 and 7% soil water content by volume of dry soil) starting July 4 to September 22, 1991 at Forest Research Laboratory's greenhouse at...

First-year effects of broadcast burning on soil infiltration and wettability in southwest Oregon

Creator:: Gaweda, Frank M.
Abstract:: Soil infiltration and wettability measurements during the first year following a broadcast burn in the Siskiyou Mountains of southwest Oregon, have illustrated the magnitude of the effects of light-to-moderate intensity burning on hydrological soil properties. A prescribed fire near White Creek in late spring significantly reduced soil infiltration for 4...

Effect of soil compaction and organic residues on spring-summer soil moisture and temperature regimes in the Sierra National Forest, California

Creator:: Troncoso, Guillermo E.
Abstract:: Soil moisture and temperature regimes during spring-summer 1996 were evaluated in plots with compaction and organic residues treatments established in 1993 at three sites in the Sierra National Forest after forest harvesting. The results indicate that the bare condition (non-compacted soil with total removal of the harvesting residues and forest...

Simplified stability assessment for low volume road cut and fill slopes

Creator:: Pratt, Randy C.
Abstract:: Many miles of roads are built in the Pacific Northwest Forests to provide access for logging and fire protection. Logging roads often cross steep mountainous terrain. Logging roads and the associated cut and fill slopes represent a discontinuity in the natural stress state in the soil mantle. These conditions result...

Using the nitrogen mineralization soil test to predict spring fertilizer N rate : soft white winter wheat grown in western Oregon

Creator:: Oregon State University. Extension Service, Hart, John M. (John Mervyn), 1947-, Christensen, Neil Walter, 1944-, Mellbye, Mark Edward, and Flowers, Michael Darrell, 1971-
Abstract:: Soft white winter wheat grown in western Oregon requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers because wheat is produced in numerous rotations that provide varying amounts of N to the wheat crop. Inadequate...
