The middle to upper Eocene Tillamook Volcanics form the basement in the Rock
Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and
andesites were erupted as shield volcanoes seaward of the strandline ontop of an older
deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...

Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....
Nitrogen deficiency during the winter where winter wheat
(Triticum aestivum L.) follows wheat and large amounts of straw
have been plowed down has been a factor limiting yield in the
Willamette Valley of western Oregon. Field experiments were
established to determine if an application of N on the stubble or...
Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...
