Fertilizing Sunflower - SF713
This revision is the results of 48 field trials from 2012-2015 studying the yield and oil response of sunflower to nitrogen and phosphorus fertilizer. The new recommendations include no phosphorus needed for sunflower and nitrogen rate based on region, tillage, soil test nitrate with a cap due to excessive lodging potential at high nitrogen rates.

Soybean Soil Fertility - SF1164
Soybean is unique in nutritional needs in the state compared to other crops. Inoculation, fertilizer application and iron deficiency chlorosis are explained.

Fertilizing Pinto, Navy and Other Dry Edible Beans - SF720
North Dakota is the leading producer of dry edible beans in the United States, with the greatest acreage of pinto beans of any state, and significant acres of navy, black and several other types of beans as well. Beans are a warm-season crop that prefers fertile, well-drained soils. Adequate, but not excessive, moisture during the growing season and a dry harvest result in high yield and quality.

Fertilizing Winter Wheat - SF1448
Winter wheat fertilization recommendations in North Dakota previously were similar to spring wheat and durum. As a larger research base was developed for spring wheat and durum, separating the winter wheat from other wheats became necessary due to their unique nutrient requirements.

Soil Fertility Recommendations for Corn - SF722
Nitrogen recommendations have been revised to consider region, soil, tillage system and irrigation/dryland management. Phosphorus, potassium, sulfur and zinc recommendations are included.

Fertilizing Malting and Feed Barley - SF723
Barley has been an important cash and rotational crop in North Dakota and the region for many years. It is important as a feed grain, but by far its economic value is linked to the malting industry. Barley requires adequate nitrogen (N) for good yields, but since grain protein in excess of industry limits often results in rejection of a crop, and since excess N leads to smaller kernel size, the line between adequate N and excessive N is fine. In addition, excessive N may result in lodging, which lowers yields and increases the incidence and severity of head blight and other diseases in some years.

North Dakota Fertilizer Recommendation Tables and Equations - SF882
The soil test recommendation tables here are based on field research data obtained in North Dakota, South Dakota, western Minnesota and the Canadian Prairie Provinces.

Fertilizing Winter Rye - SF1462
Rye previously was grouped with wheat in fertility recommendations, but rye has unique nutrient requirements that separate it from other grains. Nitrogen requirements are not as high, even though yield may be comparable to wheat. Because economic return for rye is not as high as for wheat, other nutrient recommendations are more modest. A significant amount of rye is grown organically, so suggestions for fertilizing in an organic system also are included.

Fertilizing Canola and Mustard - SF1122
Canola is an important crop in North Dakota. It is grown for its oil content for both food and fuel purposes. Nitrogen (N), phosphorus (P) and potassium (K) requirements of canola and mustard are similar to those of small grains. Sulfur (S) requirements for canola are higher than most crops. Soil test results direct fertilizer rates for N, P, K and S. Soil cores should be taken from 0 to 24 inches deep and divided into 0- to 6-inch and 6- to 24-inch samples. P and K should be analyzed on the 0- to 6-inch sample, while N and S should be tested on each depth.

Fertilizing Hard Red Spring Wheat and Durum - SF712
Nitrogen management is a key to successful wheat production. Recommendations include consideration of wheat yield and protein response to added N within three major state agri-climatology zones, and the use of wheat price and N cost in determining N rate. These recommendations are based on the concept that identifies an optimal N rate for greatest net income, not greatest yield.
