The Plant Analysis Laboratory in the Department of Horticulture at Oregon State University is currently revising tissue standards and fertilizer recommendations for wine grapes. These revisions are the result of a research program that was sponsored by the Wine Advisory board beginning in 1985. We have utilized data collected during...
The Pacific Northwest leads the United States in red raspberry
production. Many factors affect yield, including nutrition,
weather, pests, and water. Most nutritional problems can be
quickly solved once you know the specific problem, but an

Soybeans were grown in hydroponic solutions and in perlite to
devise procedures to measure plant mineral accumulation and
solution depletion over time. Electron emission spectrometry and
micro-Kjeldahl-autoanalyzer analytic techniques were used to
monitor mineral content of individual plants and their corresponding
solutions. An automated computer assisted system of converting
raw...
Intrinsic characteristics of Pacific sardines were determined. The lipid content
in sardines was initially low (6.79%) in the beginning ofthe season, increased to
22.95% in mid-August, and decreased slightly by the end of September. An inverse
correlation (R² = -0.90) was found between lipid and moisture content. Analysis
showed that...
