Contextualization is a curricular approach and a learning process in which science content knowledge is intentionally situated within a context where that knowledge can be authentically applied or observed. Many recent science education reforms include contextualization as a central tenet. Our goal in this review was to examine commonalities across...
Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...
We present double-differential measurements of antineutrino charged-current quasielastic scattering in the MINERvA detector. This study improves on a previous single-differential measurement by using updated reconstruction algorithms and interaction models and provides a complete description of observed muon kinematics in the form of a double-differential cross section with respect to muon...
Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...
Gives nutrient and lime recommendations for soft white winter wheat in western Oregon. Also discusses: impact of diseases, such as take-all root rot, on crop yield; planting in poorly drained soil; soils and settings for wheat production; fall and spring nutrient management; and postharvest evaluation of nitrogen. Includes sources of...
Silage corn makes excellent feed for dairy cattle because of its high dry-matter yield, energy content, and palatability, especially when mixed with other feed. Also, it does not accumulate potassium as do many
cool-season grass species. Nitrogen (N) is the most yield-limiting nutrient for silage corn production. Most dairies in...
Gives nutrient and lime recommendations for soft white winter wheat in western Oregon. Also discusses: impact of diseases, such as take-all root rot, on crop yield; planting in poorly drained soil; soils and settings for wheat production; fall and spring nutrient management; and postharvest evaluation of nitrogen. Includes sources of...
Recommendations in this nutrient management guide apply to spring or winter canola (Brassica napus or Brassica rapa) grown under irrigated or dryland management in rotation with a variety of crops. Recommendations for nitrogen, phosphorus, sulfur, potassium, zinc, boron, and lime are covered in this guide.
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...
Tall fescue is grown for turf or forage seed on a broad range of soils in western Oregon. Typical seed yield is 1,200 to 2,000 lb/acre. Higher yields do not require additional nutrients beyond amounts recommended in this guide. These recommendations, especially for nitrogen, are adequate for production of more...
Central Oregon is the primary U.S. hybrid carrot seed production area, supplying seed to the domestic fresh market carrot industry. Approximately 85 percent of the hybrid carrot seed planted in the United States is grown
in Jefferson and adjoining counties. The Madras and Culver areas support most of the carrot...
A comprehensive approach to nutrient management will help you ensure availability of optimum levels of nutrients for tree growth. Components of a comprehensive nutrient management strategy include:
• Soil analysis before planting (useful in predicting the need for potassium, magnesium, or lime applications)
• Observations of annual shoot growth, leaf...
Observations of annual growth and size and color of leaves and fruit are helpful in determining fertilizer needs. In addition, leaf analysis
indicates which elements are present in adequate, deficient, or excessive amounts. Soil analysis is useful in predicting the need for lime applications. Suspect a nutrient deficiency if poor...
