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 ... -
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 ... -
Fertilizer Management Strategies of Soybean (Glycine Max, L. Merrill) in Northcentral and Northwestern North Dakota
(North Dakota State University, 2019)Soybean (Glycine max L. Merrill) is a new cash crop for north central and northwestern North Dakota producers. Soils and climate in these new soybean areas differ from those regions where the current fertilizer recommendations ... -
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 ... -
The Relative Nitrogen Fixation Rate and Colonization of Arbuscular Mycorrhizal Fungi of Iron Deficient Soybeans
(North Dakota State University, 2011)Soybeans (Glycine max L. Merr.) are a symbiont of two beneficial associations: biological nitrogen fixation (BNF) with Bradyrhizobium japonicum, and arbuscular mycorrhizal fungi (AMF). Within the Northern Great Plains ... -
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 ... -
Redistribution and fate of applied ¹⁵N-enriched urea under irrigated continuous corn production
(North Dakota State University, 1996)Understanding the redistribution and fate of N is essential for justification of Best Management Practices (BMP). This project was conducted on a Hecla fine sandy loam (sandy, mixed, Aquic Haploboroll) soil at the BMP field ... -
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) ... -
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
