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. ... -
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 ... -
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 ... -
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 ... -
Evaluation of Active Optical Ground-Based Sensors to Detect Early Nitrogen Deficiencies in Corn
(North Dakota State University, 2014)Corn (Zea mays, L) is an important world crop used as livestock feed, human consumption and ethanol production. Early in-season loss of nitrogen (N) continues to be a problem in corn. Ground-based active optical sensors ... -
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 ... -
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 ... -
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, ... -
Fate and Transport of an Estrogen Conjugate 17ß-Estradiol-17-Sulfate in Soil-Water Systems
(North Dakota State University, 2013)The hypothesis of this study was that a sulfate conjugated estrogen, i.e. 17β-estradiol-17- sulfate (E2-17S), could be a precursor to free estrogens detected in the environment. The objectives of were to investigate the ... -
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 ... -
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 ... -
Greenhouse Gas Emissions and Soil Quality in Long-Term Integrated and Reduced Tillage Organic Systems
(North Dakota State University, 2016)Organic agroecosystems “rely on ecological processes, biodiversity and cycles adapted to local conditions". Soil health is “the continued capacity of soil to function as a vital living ecosystem that sustains plants, ... -
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 ... -
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 ... -
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 ... -
