The OSU Extension Soil Sensitivity Database lists
nonirrigated and irrigated soil sensitivity ratings for every
map unit of every soil survey in Oregon. These ratings
were developed for the Oregon Water Quality Decision
Aid, a tool for evaluating groundwater vulnerability to
pesticide contamination.
This investigation was motivated by the apparent increase in genetic
variability resulting from the systematic combining of gene pools
represented by winter and spring types of wheats.
It was the objective of this study to provide information regarding
the nature of this genetic variability for nine agronomic characters
in populations...
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.
The OSU Extension Pesticide Properties Database is organized alphabetically by common name. Eight parameters describing pesticide physical and chemical properties are presented. The database includes pesticides that may not currently be registered for use in Oregon, but may have been used historically or may currently be registered for use in...
The procedure described in this publication helps
you assess the potential for any specific pesticide
to travel through any specific soil to reach
groundwater.

This publication is offered as a reference to Integrated Pest Management (IPM) resources available to Oregon growers. It highlights university, federal, state, and private services and resources that provide support to growers in the implementation of IPM programs. The Guide consists of five sections: • An introduction to the National...
This thesis examines the transient and steady-state temperature performance
of a rotary regenerative heat exchanger. In contrast to previous
studies on this problem, fluid flow in the circumferential direction was
considered. Appropriate modeling was included to measure the effect of
carry-over on the differential equations describing mass and energy
conservation....
In November 1990, Oregon voters approved Ballot Measure 5,
placing an ultimate ceiling on local property tax rates of 1.5% of
market value (excluding specific levies for capital expenditure). Any
resulting shortfalls in local education revenues are to be made up by
transfers from state funds, at the expense of...
