An overview of the Oregon Water Quality Decision Aid (OWQDA) : a tool for assessing groundwater contamination risk from specific soil-pesticide combinations

Creator:: Huddleston, J. H. (James Herbert), 1942- and Oregon State University. Extension Service
Abstract:: The Oregon Water Quality Decision Aid (OWQDA) is a first-tier screening tool that allows you to make a broad determination of the likelihood that a specific chemical, when applied to a specific Oregon soil, will move through the soil and contaminate groundwater. This determination is called the groundwater vulnerability rating.

Axisymmetric infiltration

Creator:: Brooks, Royal H., United States. Office of Water Resources Research, Leclercq, Paul J., Tebbs, Richard R., and Rawls, Walter
Abstract:: The work reported herein was performed under the annual allotment from the Office of Water Resources Research to the Oregon Water Resources Research Institute. Funds were available over a three year period, but due to difficulty in acquiring graduate students, the total time spent on the project was only 21...

A soil property model for evaluating pesticide movement potential

Creator:: Vogue, Margaret A.
Abstract:: Prevention of groundwater contamination by agricultural chemicals requires an understanding of the complex processes that control pesticide movement below the soil surface. Through this understanding it is possible to try to predict which areas may be most vulnerable to contamination. The many models that have been developed to characterize pesticide...

El control del riego mediante la tensión matricial del suelo

Creator:: Shock, Clinton C., Flock, Rebecca, Feibert, Erik, Shock, Cedric A., Pereira, Andre, Jensen, Lynn, and Oregon State University. Extension Service
Abstract:: Una de las herramientas más eficaces utilizadas por el Malheur Experiment Station durante las últimas dos décadas es el sensor matricial granular (o GMS por sus siglas en inglés), el cual mide la humedad del suelo. El sensor tiene sólo 7,5 cm de largo, y normalmente se entierra verticalmente en...

Irrigation monitoring using soil water tension

Creator:: Flock, Rebecca, Flock, Rebecca, Feibert, Erik, Shock, Cedric A., Pereira, Andre, Jensen, Lynn, and Oregon State University. Extension Service
Abstract:: One of the most important tools we have been using at the Malheur Agricultural Experiment Station over the past two decades is the granular matrix sensor (GMS, Watermark Soil Moisture Sensor, Irrometer Co., Riverside, CA), which measures soil moisture. It is only about 3 inches long and normally is buried...

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

Creator:: Anderson, Nicole P., Hart, John M. (John Mervyn), 1947-, Christensen, Neil Walter, 1944-, Mellbye, Mark Edward, Flowers, Michael Darrell, 1971-, and Oregon State University. Extension Service
Abstract:: Soft white winter wheat is grown in western Oregon and requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers. Wheat obtains N from two sources: soil and fertilizer. Both available and mineralizable N can be...
