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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. ... -
Can We Increase Crop Yield Adopting Tile Drainage in Fargo Clay Soil?
(North Dakota State University, 2018)Subsurface drainage has recently become common for agriculturally productive soils and key to maintain and improve crop production in poorly drained, frigid clay soils. The first study was conducted for four years (2014-17) ... -
Phosphorus Dynamics and Crop Productivity in Bakken Crude-Oil Remediated Soils
(North Dakota State University, 2018)Thermal desorption (TD), a remediation method used to remove hydrocarbons from contaminated soils, may cause changes in soil properties that threaten soil function and plant productivity. The goal of this research is to ... -
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. ... -
Relationship of Vegetation Indices from Drone-Based Passive Optical Sensors with Corn Grain Yield and Sugar Beet Root Yield and Quality
(North Dakota State University, 2019)The main goal of this study was to calibrate small unmanned aircraft system (SUAS) based vegetation indices with fertilizer-N application rate and yield for corn and sugar beet. It was hypothesized that canopy reflectance ... -
Superabsorbent Polymer Effects on Soil Physical Properties and Use as a Compaction Alleviation Amendment in Surface Coal Mine Reclamation
(North Dakota State University, 2019)Surface coal mine reclamation is challenged by alterations in soil characteristics, compaction being the most plant-yield reducing. Superabsorbent polymers (SAPs) ability to retain large volumes of water gives them the ... -
Impacts of Kentucky Bluegrass and Patch-Burn Grazing Management on Soil Properties in the Northern Great Plains
(North Dakota State University, 2019)Kentucky bluegrass (Poa pratensis L.; hereafter referred to as bluegrass) has rapidly invaded the northern Great Plains over the past three decades, leading to declines in native plant diversity. A knowledge gap exists ... -
Soil Biological Temporal Variability as Functions of Physiochemical States and Soil Disturbance
(North Dakota State University, 2019)Within our ecosystems, soil biota control an array of functions, such as nutrient cycling and decomposition, and have been pursued as a soil quality indicator. Though microbial communities are known to be a reflection of ... -
Can Soil Microbial Activity Be Improved With the Use of Amendments?
(North Dakota State University, 2020)Low microbial activity and associated nutrient cycling are concerns in agricultural problem soils. The objectives of this study were to investigate microbial response on problem soils to amendments, drying-wetting cycles, ... -
The Effect of Salinity on Soil Microbial Community Structure
(North Dakota State University, 2020)Soil salinity is a widespread problem that affects crop productivity. We expect that saline soils also have altered microbial community structure, soil food webs and related soil properties. To test this, we sampled field ... -
Seeding Time and Interseeded Cover Crop Species Influence Sugarbeet Yield and Quality
(North Dakota State University, 2020)Field experiments were conducted to evaluate cover crop interseeding time and species effect on sugarbeet production during 2018 and 2019 growing seasons. Cover crops were first interseeded in June and second interseeding ... -
Soybean Water Stress Development and Mitigation in West-Central North Dakota
(North Dakota State University, 2020)In recent years, soybean [Glycine max. (L.) Merr.] production has moved into west-central North Dakota, an area known for common deficits between potential plant water use and annual rainfall. Soybean seed yield reductions ... -
Soil Biological Functioning and Recovery in Soils Disturbed From Bakken Oil and Gas Activities
(North Dakota State University, 2022)Oil and gas activity-related soil disturbances can alter soil properties and reduce microbial function, which is crucial for nutrient cycling and proper soil function. The goal of this research was to investigate effects ... -
Calcium Acetate: An Alternative to Gypsum for Brine Impacted Soils
(North Dakota State University, 2022)With North Dakota being ranked as a leading producer of oil and natural gas in the United States, the possibility of accidental produced water (aka “brine” or “salt water”) spills is a continuous concern. Brine water poses ... -
An Examination of Land Preparation Methods to Alleviate Common Issues Associated With Pipeline Reclamation
(North Dakota State University, 2022)Post-seeding land preparation methods can improve reclamation success; however, limited research is available for the Williston Basin. A field study evaluated four treatments: land imprinting, hydromulch, straw crimping, ...
