As the capital requirements for the modern dairy enterprise increase, the Oregon milk producer and his lender need more information concerning the profitability, solvency and liquidity of the enterprise on which to base their financial decisions. This research examines three areas where more information could be used to
evaluate financial...
The traditional practice on beef cow-calf ranches in the high
desert region of Eastern Oregon has been to breed the cows to calve
in the Spring months. Interest has been growing recently in the practice
of Fall-calving; that is, breeding cows to calve in the months of
October and November....
Ranchers in the high desert area of Eastern Oregon traditionally
market their calves when they are weaned in late fall.
This is the time when the market prices for calves are at a
seasonal low.
In this study the economic feasibility of various alternative
management and marketing strategies for the...
Commercial production of soybeans in Oregon has been limited. In
1977, less than 1,500 acres were grown, primarily in the Columbia Basin
area. However, interest in soybeans as a possible "new crop" for Oregon
has arisen because of the (1) recent strong soybean price, (2) the high
cost of transporting...
This thesis, although dealing specifically with Oregon Agricultural
cooperatives, has significance for agricultural cooperatives on
a national basis when discussing equity financing.
The central issue is whether a patron may in effect transfer
his cooperative equity holding to another person without impairing
the total function of the cooperative? To answer...
Studies were conducted to determine the uniformity of three
commercial seed lots of ryegrass (Lolium spp.) and the effects of lot
size on lot uniformity. Individual bag-samples were taken from each
seed lot. Factors considered were percentage purity, annual ryegrass,
perennial ryegrass, weed, other crop, inert matter, and germination.

A diversity in climate, geologic parent material, and soil
characteristics exist in Jackson, Josephine, Coos, and Douglas
Counties of southwest Oregon. Previous field trials and soil testing
results have revealed uncertainties as to the phosphorus (P) status
of the soils in this area. Twenty-four sites from nine agriculturally
significant soil...
National farm legislation seeks to moderate the conditions of low farm incomes and commodity price instability. Homogeneity of producer response is generally assumed in national models of aggregate commodity supply. Differing conditions of soil, climate, production systems, costs of production, markets, etc., could cause disparate acreage responses to the commodity...
In situ light and dark planktonic and benthal respirometers were
used to measure the oxygen requirements of Yaquina estuary water
and benthal deposits. Respirometer devices were constructed so that
actual conditions of mixing could be simulated and benthal deposit

The "unusual" behavior of agricultural land prices is the subject of considerable debate and controversy and is the object of this research. There is little doubt that land prices have been increasing steadily since 1959 and dramatically throughout the decade of the 1970's. However, there is widespread disagreement among economists,...
