This publication lists the components of a comprehensive nutrient management strategy and provides nutrition guidelines for mature and new hazelnut orchards.
Несколько видов ягодных культур коммерчески выращивают в штате Орегон, в том числе, летом плодоносящие и плетье-плодоносящие малины (красная и черная) и ежевика то есть ажина. Эта публикация направлена на оценку содержания и внесения питательных веществ, применяющихся в выращивании кустарных ягод в западной части Орегона.
This online module provides information on nutrient needs of grapevines, symptoms of deficiency and/or toxicity, and vineyard nutrient management. A section of this module explains how to diagnose non-nutrient problems such as damage from diseases, insects, drought, sunburn, and herbicides.
Discusses nutrient management and fertilizer recommendations for lime, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, chloride, and micronutrients on annual ryegrass grown for seed. Includes discussion of research and explanation of nutrient management recommendations.
During the past 50 years, plantation Christmas tree production has grown in acreage and sophistication. Nitrogen applications with a tuna can have been replaced by precise, mechanized application of a wide array of nutrients and lime.
Current nutrient management programs must focus on three concepts for success.

The objectives of this study were to evaluate the performance of wood-frame shear walls under monotonic and cyclic loads by: 1) determining variability of shear wall performance; 2) comparing performance of walls under each loading protocol; 3) evaluating effects of anchorage on wall perfor-mance; and 4) evaluating performance of walls...
The co-existence of hunger and obesity continues to garner media, research, and advocacy attention. Oregon State University Extension Service examined the
research to provide an overview of this seeming paradox—how can a person be hungry and obese?
Many studies have shown that dairies consistently overfeed nutrients such as phosphorus (P) and potassium (K). This practice is expensive and potentially damaging to the environment and to animal health. This publication suggests ways to improve feed management and thus avoid overfeeding P and K. Proper ration balancing is good...
Field-grown red maple (Acerrubrum) trees often develop foliar chlorosis during mid- to late summer. Initially, the condition appears as mild interveinal chlorosis in newly developing foliage. As symptoms intensify, entire leaves turn chlorotic. Under severe conditions, interveinal necrosis occurs. Chlorotic plants often have reduced height and caliper. The chlorosis is...
Several types of caneberries are produced commercially in Oregon, including summer-bearing and primo cane fruiting red raspberries, black raspberries (blackcaps), and blackberries. This publication addresses nutrient assessment
and application for caneberries produced in western Oregon.
In this area, caneberries typically are planted on Aloha, Jory, Newburg, Willamette, Woodburn, or Saum...
