Anhydrous Ammonia: Managing The Risks (AE-1149 (Revised))
Anhydrous ammonia has the potential to be one of the most dangerous chemicals used in agriculture today. It is used and stored under high pressures, which requires specially designed and well-maintained equipment. Those who work with anhydrous ammonia must be trained to follow exact procedures in handling it.

Nitrogen Extenders and Additives for Field Crops (SF1581)
Nitrogen is lost from soil through the activity of soil bacterial transformation of ammonium to nitrate, and from nitrate, the N can be lost leaching or denitrifcation. There are chemistries available that inhibit the transformation of ammonium to nitrate, and there are also compounds that inhibit urease enzyme activity, decreasing the risk of ammonia volatility.

Soil Testing Unproductive Areas - SF1809
This publication is intended to provide information on how to sample and analyze area that are affected by soil salinity and sodicity. It explains how to take soil samples representing the affected areas, what kind of tests are needed to assess salt and sodium levels and how to interpret the results.

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.

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 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.

Active Optical Sensor Algorithms: How they work and how they can be used to calculate N requirements in the field - SF1176-5
Research from 2011 to 2013 has resulted in a data base that supports to use of active-optical sensors to direct side-dress N rates in corn. Previously, rates were determined using a grower best guess.

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.

Managing Saline Soils in North Dakota - SF1087
Saline soils have salt levels high enough that either crop yields begin to suffer or cropping is impractical. Excessive salts injure plants by disrupting the uptake of water into roots and interfering with the uptake of competitive nutrients. Several factors contribute to the development of saline soils in North Dakota, but a high water table is a prime requirement. Recognizing how and why salts accumulate is the first step in farming profitably on land interspersed with saline soils. Preventing further encroachment of salinity and addressing remediation strategies are other steps.

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.
