Soil & Fertilizer

Site-specific Farming: Economics and the Environment - SF1176-4

Site-specific farming technologies can result in economic gain for farmers if used correctly, and can also decrease impact from the environment from off-sight movement of fertilizers to groundwater and surface waters.

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 lists all the soils in the state with relevant properties and categorizes them as irrigable, conditional or nonirrigable.

Soil Sampling as a Basis for Fertilizer Application (SF990 Revised)

This publication was first made available in 1998. Since then, there has been significant research into soil testing methods. This revision will include these updated findings and recommendations.

North Dakota Clay Mineralogy Impacts Crop Potassium Nutrition and Tillage Systems (SF1881)

Clay mineralogy is important in directing potassium rate to corn and other crops in North Dakota. It also has an impact on tillage systems and their success and proper management.

Limitations of the Sulfate-sulfur Soil Test as a Predictor of Sulfur Response (SF1880)

In the past dozen years, sulfur deficiency in the north central region has become common in historically unaffected soils. The reasons include higher crop yield and the associated increased demand for soil sulfur, but also the clean air as a result of regulation. The sulfur soil test has been used for years, but researches now find it has little value.

Site-specific Farming: Yield Mapping and Use of Yield Map Data (SF1176-3 Revised)

This circular, although originally published in 2008 is still relevant and useful as is. Although almost half of ND farmers utilize some site-specific technology, the other half would also benefit from its use.

Pinto Bean Response to Phosphorus Starter Fertilizer in East-central North Dakota (A1883)

This is a production reference to highlight pinto bean fertilizer research.

Site-specific Farming: What is Site-specific Farming? (SF1176-1 Revised)

This circular, although originally published in 2008 is still relevant and useful as its. Although almost half of ND farmers utilize some site-specific technology, the other half would also benefit from its use.

Site-specific Farming: Developing Zone Soil Sampling Maps (SF1176-2 Revised)

This circular, although originally published in 2008 is still relevant and useful as is. Although almost half of the ND farmers utilize some site-specific technology, the other half would also benefit from its use.

Soybean Soil Fertility - SF1164

All of NDSU soil fertility recommendations now have no yield-based formulas. The soybean fertility recommendations were modified to be in line with these new guidelines.

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.

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.
