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.

Environmental Implications of Excess Fertilizer and Manure on Water Quality (NM1281 )
When nutrients and other pollutants associated with animal manures and commercial fertilizers are not managed properly, they can affect plant and animal life (including humans) negatively. Some of these impacts include algae blooms causing the depletion of oxygen in surface waters, pathogens and nitrates in drinking water, and the emission of odors and gases into the air.

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.

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.

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.

Developing Zone Soil Sampling Maps - SF1176-2
In the northern Great Plains region, most soil sampling is conducted to determine the residual soil nitrate (N) available following a previous crop that can be used to reduce the N fertilizer required for the next crop. Zone soil sampling has been very effective in revealing residual nitrate patterns and amounts in fi elds. To develop zone boundaries to direct soil sampling, a number of tools can be used. A regional project in North Dakota, Montana and Minnesota concluded that all the tools detailed here can be used to develop zones.

Yield Mapping and Use of Yield Map Data - SF1176-3
Combine yield monitors are growing in popularity. Data are utilized to build fi eld yield maps in certain years or yield frequency maps during multiple years. Maps serve as location-year record of management and may be predictive of yield potential and soil nutrient variability for future crop management decisions.

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.
