This publication describes how to estimate lime application rate and lists criteria for choosing liming materials (source), lime application method (placement), and how often to apply lime (frequency).
This publication incorporates 20 years of field research by OSU faculty comparing two grass-seed residue management methods: full straw load (straw is chopped and left on the field) and clean nonthermal (straw is baled and removed from the field). Comparison includes discussion of seed yield and quality, nutrient management considerations...

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...
This publication provides an overview of soil testing and general guidelines for interpreting soil test results for nitrogen, phosphorus, sulfur, potassium, calcium, magnesium, boron, zinc, copper, manganese, iron, molybdenum, chloride, sodium, soluble salts, organic matter, cation exchange capacity, pH, and lime. For each test, the document describes what is measured,...

This publication is a technical and practical guide for soil acidification in commercial fields. It explains the soil chemistry involved, how to determine whether pH adjustment is feasible, and methods for acidifying soil. This guide is divided into five sections:
• Understanding soil pH
• The problem—iron chlorosis
• Causes...
This publication provides information on the timing and pattern of biomass accumulation and nitrogen (N) uptake for a variety of Pacific Northwest crops. You can use this information to schedule N fertilizer applications for maximum efficiency. To achieve near-maximum crop yields, an adequate supply of available N must be present...
Fertilizing hops improves yield and quality by supplying the crop with ample nutrition in advance of demand. Producers must combine this goal with production costs and environmental stewardship. Fertilization should be based on yield and quality response, experience, and economics. Unfortunately, limited experimental data exist linking modern cultural practices, current...
Recommendations in this fertilizer guide apply to tillage fallow-winter wheat and chemical fallow-winter wheat cropping systems. This guide is one of a set of publications that address the nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon.
Recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc are covered...
Most irrigation water in Oregon is of excellent quality. Occasionally a deep well yields water that is too salty for irrigation, or contains constituents that are detrimental to plants or soils. Water can be of poor quality for irrigation because of the amount of impurity (salt) it contains or the...
Good management practices are essential if optimum fertilizer responses are to be realized. These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest.
Because of the influence of soil type, climatic conditions, and other...
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...
Perennial ryegrass is grown for turf or forage seed on a broad range of soils in western Oregon. All perennial ryegrass varieties are similar in their nutrient requirements. Typical seed yield is between 1,400 and 1,800 lb/acre.
Higher seed yields (up to 2,500 lb/acre) may be produced on better soils,...
Fertilizer recommendations in this guide are based on the use of well-adapted varieties and disease free plants, selection of suitable soils, disease and insect control, weed control, and proper irrigation. Application of these management practices is essential to realize optimum fertilizer response.
Strawberries respond to generous amounts of soil organic...
Three types of fine fescue—Chewings, red, and hard— are typically grown for turf seed on Jory or Nekia soils in the foothills of the Willamette Valley. Recommendations in this guide assume production in this setting and are based on research from large and small plots throughout the area. During the...
Fruit tree fertilization is a standard grower practice intended to supplement soil-supplied nutrients. Both soil-applied fertilizers and nutrients stored within the tree are important. Tree reserves are the major source of nutrients for developing tissues before petal fall. Current-season growth and
yield are influenced by nutritional status, which in turn...

Annual ryegrass varieties such as ‘Gulf’ are grown for seed on poorly drained soils of the south Willamette Valley, including Dayton, Concord, and Bashaw. Recommendations in this guide are based on research throughout this production area. Management practices from seedbed preparation to harvest must be performed in an appropriate and...
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...
Commercial blueberry production in Oregon is dominated by the northern highbush type, although rabbiteye blueberries are produced on limited acreage.

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...
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...
Soil acidification sometimes is necessary for optimum plant growth
west of the Cascade Mountain Range. Commercial producers of
blueberries, azaleas, rhododendrons, and other ornamentals may
need to reduce soil pH for optimum production.
Soil acidification is best performed prior to planting; it is much
more difficult in established plantings. No...
