Soil & Fertilizer

Fertilizing Hard Red Spring Wheat and Durum (SF712 Revised)

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.

North Dakota Fertilizer Recommendation Tables and Equations (SF882 Revised)

Most of the nutrient recommendations for North Dakota crops were revised this year. For these crops and for minor crops that do not have a specific nutrient circular, this publication summarizes 27 crops or crop categories.

Compatibility of North Dakota Soils for Irrigation (AE1637)

This publication is intended as a first step to help current and prospective irrigators understand the principles behind the irrigability of soils in North Dakota. This publication should be used in combination with soil survey information of the land to be irrigated. Soil surveys of every county in North Dakota have been completed and documented.

Fertilizing Potato in North Dakota SF715 (Revised)

The previous edition provided a nutrient rate to potato regardless of varietal efficiency nad harvest date. This edition provides this updated information and also recommendation potassium based in part on soil clay chemistry.

Soil Fertility Recommendations for Field Pea, Lentil and Chickpea in North Dakota (SF725 Revised)

This publication provides the latest recommendations of fertilization for field pea, lentil and chickpea according to the most recent research data.

Fertilizing Sugar Beet in North Dakota (SF714 Revised)

Sugar beet growers in this region are paid based on the tons of recoverable sucrose that is extracted from their crop. Therefore, sugar beet profitability depends on producing a high-tonnage crop that is high in sucrose percentage.

Fertilizing Winter Wheat (SF1448 Revised)

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.

Alfalfa Soil Fertility Requirements in North Dakota Soils (SF1863)

Alfalfa is the most important forage grown in North Dakota. This manuscript details its soil fertility requirements more extensively than any publication has previously. The previous circular related to alfalfa soil fertility also included clovers, however the soil fertility requirements of clover and alfalfa are very different and alfalfa frankly deserves better information.

Fertilizing Alsike Clover, Birdsfoot Trefoil, Red Clover and Sweetclover in North Dakota (SF1865)

Fertilization of clovers is different from alfalfa, so the recommendations requirements need to be different from those of alfalfa.

Soil Fertility Recommendations for Corn SF722 (Revised)

These recommendations are updated to include new potassium recommendations based on recent research.

Soil Fertility Considerations for Buckwheat in North Dakota SF724 (Revised)

Buckwheat is grown every year in North Dakota and is an important specialty crop grown for grain in conventional and organic farming systems. It's ability to cycle phosphorus from slowly available to more available forms is referred to in this update.

Fertilizing Pinto, Navy and Other Dry Edible Bean SF720 (Revised)

Dry beans are unique in crop fertilizer needs. This circular directs growers to an appropriate strategy for fertilizer efficiency and high yielding, high quality dry bean harvests.

Fertilizing Flax SF717 (Revised)

Flax is an ancient crop. Evidence indicates it was cultivated in the Middle East as early as 7000 B.C. Ancient Egyptians cultivated flax extensively as a fiber crop for linen production, while other peoples utilized the seed for food as well as the fiber. Today, growers in Canada and the U.S. grow seed flax varieties.

FERTILIZING CANOLA and MUSTARD SF1122 (Revised)

This is an updated circular for a crop that is important to the livelihood of North Dakota framers north of highway 2, generally. All references to yield-based nutrient formulas are taken out of this revision.

Anhydrous Ammonia: Managing The Risks

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.

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

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

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

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.
