How Salinity Influences Soil Organisms: Earthworms, Archaea, Bacteria and Fungi
(North Dakota State University, 2023)Soil salinity is a naturally-occurring issue in the Great Plains. Current standards for saline soil designation are based on plant tolerance levels. This thesis expands salinity knowledge into salinity responses of other ... -
An Evaluation of Electrical Conductivity Meters for Making In-Field Soil Salinity Measurements
(North Dakota State University, 2010)Soil electrical conductivity (EC) can be used as a parameter to assist agricultural producers in making economically important management decisions. Since particular crops and crop varieties respond dynamically to soluble ... -
Shifting Perspectives: Desocialization and the Journey Toward Critical Consciousness
(North Dakota State University, 2010)The purpose of this study was to investigate how a service-learning course fosters students' development of a critical consciousness. Participants of this research study were students who participated in the 2009 ... -
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 ... -
Effects of Major Flooding on Water and Sediment Characteristics in an Urban Enviromnent
(North Dakota State University, 2011)Spring flooding of the Red River of the North is a common phenomenon, but no infonnation exits on how these flooding events impact both water and sediment quality within an urban area. The objectives of this study were ... -
Effects of Swine Slurry on Sorption of 17~-estradiol to Soil
(North Dakota State University, 2011)178-estradiol (E2) is a potent endocrine disrupting compound that is found in swine manure. Liquid swine manure or otherwise knov.n as swine slurry is commonly used as a form of fertilizer in agricultural practices. ... -
Evaluation of 1:5 Soil to Water Extract Electrical Conductivity Methods and Comparison to Electrical Conductivity of Saturated Paste Extract
(North Dakota State University, 2011)Conducting a 1 :5 soil:water extract to measure electrical conductivity (EC) is an approach to assess salinity and is the preferred method used in Australia. However, the influence of salinity on plant growth is predominantly ... -
Corn Response to Sulfur in the Red River Valley
(North Dakota State University, 2022)Sulfur (S) deficiency symptoms are becoming common to crops grown in the Red River Valley of North Dakota and Minnesota. Corn (Zea mays L.) response to incremental sulfate-S (0, 11, 22, 33, and 44 kg S ha-1) was studied ... -
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, ... -
Proposed Nonparametric Tests for the Simple Tree Alternative for Location and Scale Testing in a Mixed Design
(North Dakota State University, 2022)Six nonparametric tests are proposed for the mixed design consisting of a randomized complete block design (RCBD) and a completely randomized design (CRD). The proposed tests are designed to test for differences in location ... -
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 ... -
Evaluating Ornamental Grasses for the Challenging Rain Garden Environment
(North Dakota State University, 2022)Four experiments were conducted to determine the growth and survival of seven species of perennial ornamental grasses, tufted hairgrass [Deschampsia cespitosa (L.) P. Beauv.], switchgrass (Panicum virgatum L.), big bluestem ... -
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 ... -
Understanding the Role of Soils in Decision Making: Urban Agriculture and Septic Systems
(North Dakota State University, 2022)Rural and urban dwellers frequently face decisions relating to human health. Among these are issues pertaining to water quality, and the availability of safe and nutritious food. Rural septic systems treat household ... -
Soil Moisture Prediction Using Meteorological Data, Satellite Imagery, and Machine Learning in the Red River Valley of the North
(North Dakota State University, 2021)Weather stations provide key information related to soil moisture and have been used by farmers to decide various field operations. We first evaluated the discrepancies in soil moisture between a weather stations and nearby ... -
The Biogeochemistry of Soil at Depth Within the Wetland Landscape of the Prairie Pothole Region
(North Dakota State University, 2021)The impact of agricultural practices on wetland ecosystems in the Prairie Pothole Region (PPR) has long been recognized but little is understood about impacts on the biogeochemistry of the wetlands at depth. Understanding ... -
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 ... -
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 ... -
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 ...
