Marginal agricultural and forest lands are currently a focus of concern for public land use agencies in Oregon. Two alternatives for evaluating marginal agricultural lands are the Land Evaluation and Site Assessment (LESA) model of the U.S. Soil Conservation Service and the marginal lands criteria of the 1983 Oregon Legislature's...
Marginal agricultural land is currently a focus of concern for
public land use agencies in Oregon. Two approaches for evaluating marginal
agricultural lands are the Land Evaluation and Site Assessment (LESA) model
of the U.S. Soil Conservation Service, and the marginal lands criteria of
the 1983 Oregon Legislature's Senate Bill...
Agricultural field burning in Oregon's Willamette Valley
has been an accepted farming practice for sanitizing fields and removing
stubble and residues left on fields after harvest since the
early 1940s. Unfortunately, the smoke and debris created by the
burning in combination with other pollutants have been causing health
and environmental...
Marion County had a 1976 cash receipt from all farm products
amounting to $110,429,000. Much of this farm value was produced on the
county's 410,350 acres of class I through IV soils. These soils, regardless
of productivity, also have potential for a variety of other
non-farm uses. It is this...
The Chelan Valley is one of several valleys located on the eastern slope of the Cascade Mountains contributing to the leadership of Washington in apple production. Since the nature of the activity in the Chelan Valley is typical of all these producing areas,it was selected as a case study of...
Attempts to map the distribution of acidic
deposition have been inadequate, particularly in areas of
seasonal or limited rainfall. Ambient air concentrations
of acid precursors may be used to monitor and map the
distribution of potential acidic deposition. A network of
stations in California currently monitor these ambient air
concentrations....
The siting of a new industrial plant generally results
from the favorable match of the needs of an industrial
firm arid the assets of a community. Citizens of
Oregon have taken a very active role in planning and decision
making at the local level due to legislation in
the past...
The value per-acre and annual amortization of
rural land varies dynamically by parcel size. There are
several adjustment factors or independent variables
spatial, productive and development potential which affect
the market value of all rural land. The evaluation of
these must be accomplished by parcel size to be realistically
equated....
Re searchers have long tried to correlate weather factors with plant disease occurrences. However, inconclusive results have usually been obtained because most plant diseases have biologic as well as climatic optimums.
In this study, thirty weather variables were correlated, by the stepwise regression method in a computer, to the amount...
Rivers are becoming increasingly popular recreation
resources as land and water use competition intensifies. The
first river basin board in Nova Scotia was formed to manage
the Shubenacadie-Stewiake Rivers under multiple use objectives.
The board required an estimation of the recreation resources
of the Stewiake River and after a review...
