The relationship between sea level and wind stress in a region of
known upwelling was studied for an eleven-month period during
1933-34.
Sea level data, obtained from observations taken by the Coast and
Geodetic Survey, were processed to remove astronomic tidal constituents
and inverted barometer effect. Regression analysis was used...
Jackson County, Oregon is noted for the production of high quality
pears. It is the fourth leading pear producing county in the United
States and is the number one producer of winter pears. This thesis
analyzes in detail the many aspects of the pear industry in the county.
Climate, soils,...
The research presented in this thesis evaluated the effects of
uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due
to the biological importance of Na and K, these two ions were
studied in the greatest detail.
The results of this research showed that, at UO₂⁺⁺ concentrations...
The objectives of this study were to evaluate and compare the
availability of native and applied P in Central Oregon pumice soils
with that in Willamette valley soils and calcareous soils from Eastern
Oregon. The experimental work to meet these objectives included
laboratory and greenhouse studies.
The removal of P...
Incubation experiments with an acid poorly drained soil have
shown that the application of neutral soluble salts influenced the level
of extractable Mn. The application of a salt which lowered the soil
pH either increased the extractable Mn or retarded the oxidation
and/or fixation of extractable Mn. This effect was...
