Management recommendations focusing on rate, timing, source, and method of nutrient application for irrigated wheat production in eastern Oregon.
Addresses nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Includes recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc.
Explains water-quality issues related to excess phosphorus in surface waters. Provides specific ways for homeowners, commercial property managers, irrigated row crop growers, dryland farmers, ranchers, and confined animal feeding operators to reduce phosphorus loss to surface waters.
Describes impacts of nitrogen overfertilization and uneven irrigation on groundwater in Willamette Valley, Oregon. Recommends that mint crop growers use stem testing to gauge nitrogen needs more closely and advises growers on how to improve irrigation system efficiency.
Some farmers in the Inland Pacific Northwest have reported lower grain yield of spring cereals with no-till (NT) compared to conservation tillage (CT). A 4-year field study was conducted in a 12-inch annual precipitation zone to determine tillage method and sowing rate effects on seed-zone water, seed-zone temperature, plant stand, grain yield, grain yield components, and straw production for three spring-sown cereal species.
Presentation by Kurtis L. Schroeder, Cropping Systems Agronomist & Plant Pathologist, on Soilborne Diseases of Cereals: Identification and Management for the Integrated Pest Management Website hosted by Umatilla County Extension Service.
Many farms will be required to go through some sort of Good Agricultural Practices (GAP) certification process in order to satisfy buyer demands or because they will be required to under the new Food Safety Modernization Act. ...
Land-grant soil scientists in the Pacific Northwest have written this publication to share information and to relate in-depth the wheat and N management issues related to grain protein enhancement. The focus is on irrigated wheat, but many of the principles will apply to rain-fed wheat as well.
