Corn Response to Sulfur Fertilizer in the Red River Valley
(North Dakota State University, 2018)A study was conducted at ten locations in North Dakota and Minnesota in 2016 and 2017 to evaluate corn response to different sulfur (S) application rates and to determine the relationship between corn yield and plant tests. ... -
Predicting Soil Health and Function of the Barnes Catena Using Evapotranspiration, Vegetative, Geologic, and Terrain Attributes in the Eastern Glaciated Plains of North Dakota
(North Dakota State University, 2018)The benchmark Barnes soil series is an extensive northern Great Plains upland Hapludoll that is vital to the region. Accelerated erosion has degraded Barnes agricultural soil quality, but with unknown extent or severity. ... -
Screening Hard Red Spring Wheat Cultivars for Reduced Phosphorus Fertilizer Requirement
(North Dakota State University, 2017)Phosphorus (P) is a common macronutrient required for hard red spring (HRS) wheat (Triticum aestivum L.) growth and yield expression, and is a significant expense for farmers. The objective of this study was to screen 89 ... -
Recalibration of Soil Potassium Test for Corn in North Dakota
(North Dakota State University, 2017)Corn (Zea mays L.) production has greatly increased in North Dakota since the 1990s; yet, potassium (K) fertilizer recommendations for corn in North Dakota still date from the late 1970s and early 1980s when corn grain ... -
Chemical and Biological Characteristics of Thermally and Chemically Disturbed Soil in Northwestern North Dakota
(North Dakota State University, 2017)Thermal desorption (TD) remediates hydrocarbon-contaminated soil by heating the soil (200 to 500 °C) to volatilize the hydrocarbons, effectively removing the contaminant from the soil. If the soil is then used for agricultural ... -
Biological Response to Sulfate Salinity in Richland County, North Dakota
(North Dakota State University, 2016)Soil salinization is a major threat to agricultural ecosystems. Consequently, an understanding of agro-ecosystem functions affected by increasing levels of soil salinity is critical for land management. The purpose of this ... -
Influence of Amendments on Chemical and Biological Properties of Sodic Soils
(North Dakota State University, 2016)Improving productivity of sodic soils has become a concern in North Dakota because of the desire for more land for producing crops. Field and incubation studies were conducted to determine the impacts of different amendments ... -
Brine-Contaminated Soils in Western North Dakota: Site Assessment Methodology and a New In-Situ Remediation Method
(North Dakota State University, 2016)Anthropogenic soil salinity caused by produced water (i.e., brine) contamination is an issue in all oil and gas producing regions. The objectives of this research are to develop soil electrical conductivity (EC) conversion ... -
Nitrogen and Phosphorus Recalibration for Sunflower in North Dakota
(North Dakota State University, 2016)Sunflower is one of the most important annual crops grown for edible oil in the world and is grown in North Dakota and the northern Great Plains more than any other region in the United States. Sunflower production and ... -
Spring Wheat (Triticum aestivum L.) Response to Nitrogen (N) Loss Management and Sulfate-Based Soil Salinity
(North Dakota State University, 2016)The first study was conducted during 2014 growing season at Glyndon, MN to evaluate the effectiveness of nitrification inhibitor or both urease and nitrification i.e. double inhibitors on reducing N losses in a rainfed ... -
Sugarbeet Yield and Quality Response to Nitrogen Fertilizer Rate and In-Season Prediction of Yield and Quality Using Active-Optical Sensor
(North Dakota State University, 2016)Nitrogen (N) management is one of the important factors in sugarbeet production. Under-application of N-fertilizer results in lower root yield while over-application of N-fertilizer can result in decreased sugar concentration ... -
Soil Salinity and Sodicity Impacts on Soil Shrinkage, Water Movement and Retention
(North Dakota State University, 2015)Saline, sodic, and saline-sodic ground waters are problematic throughout the Northern Great Plains and Red River Valley. High sodium adsorption ratio (SAR) and low electrical conductivity (EC) of soil solution and irrigation ... -
The Influence of Soil Salinity Gradients on Soybean [Glycine Max (L.) Merr.] and Corn (Zea Mays L.) Growth
(North Dakota State University, 2015)An estimated 2.3 million hectares are salt-affected in North Dakota (Brennan and Ulmer, 2010), a number increasing due to land management, climate, and crop choice. As a result, yield reductions are noted for salt-sensitive ... -
Evaluation of Soil Potassium Test to Improve Fertilizer Recommendations for Corn
(North Dakota State University, 2015)A study was conducted at thirteen locations in North Dakota and Minnesota in 2013 and 2014 with the objectives of determining difference between the soil potassium (K) results based upon air-dried (KDry) and field-moist ... -
Foliar Application of Iron Chelated Fertilizer and Surfactants for Management of Iron Deficiency Chlorosis in Soybeans
(North Dakota State University, 2016)Iron deficiency chlorosis (IDC) is a production challenge for farmers growing soybeans [Glycine max (L.) Merr.], especially in the Red River Valley. It is critical to correct this deficiency as soon as symptoms arise before ... -
The Use of Sediment Removal to Reduce Phosphorus Levels in Wetland Soils and the Distribution of Plant-Available Phosphorus in Wetland Soils and its Potential Use as a Metric in Wetland Assessment Methods
(North Dakota State University, 2014)Plant-available phosphorus (P) in wetland soils and its relationship with wetland communities and condition is somewhat unknown in the Prairie Pothole Region (PPR) in North America. Research objectives were to determine ... -
Evaluating Dynamic Soil Change in the Barnes Soil Series Across Eastern North Dakota
(North Dakota State University, 2015)Quantifying long-term, global soil change is of the utmost importance as the human population continues growing and food security needs intensify. North Dakota presents a unique opportunity to study dynamic soil change ... -
