Cereal Grain Nutrient Management

Nutrient Management In Cereal Grain Crops

Nutrient management is important for wheat production before planting and in late winter. Soil pH, phosphorus, potassium, calcium, and magnesium need to be adequate before planting. A common problem with direct seed or no-till wheat production is low soil pH in the top 2-3 inches of soil. Stratified soil samples should be taken before direct seeding.  Nitrogen typically is the nutrient most limiting to wheat production. The amount of spring N to apply can be determined from a soil test when a sample is collected in late January. If consecutive crops of wheat are planted, soil pH, phosphorus, chloride, and nitrogen source changes substantially from first year wheat.

Compared to winter wheat, less nitrogen is required for barley, oats or spring wheat compared to winter wheat. For barley, use approximately 80% of the winter wheat nitrogen rate. For oats use approximately 60% of the winter wheat rate and for spring wheat, apply between 50 and 60 % of the winter wheat nitrogen rate.

Cereal Grain Weed Management

The OSU Weed Science Group conducts greenhouse, laboratory and small plot herbicide evaluation trials in support of the development of weed management activities in the diverse cropping systems of Western Oregon.  Labeled and experimental herbicides are evaluated for crop safety and weed control efficacy in the following crops:  Winter and spring wheat, cool-season grasses grown for seed, native cool-season grasses and forbs grown for seed, canola, meadowfoam, camelina, clovers and peppermint among others.

California Brome

Italian Ryegrass

Rattail Fescue

Ripgut Brome

Wild Oats


Annual Sowthistle

Catchweed Bedstraw
