A Faunal Survey of Coleoptera, Hemiptera (Heteroptera), and Lepidoptera Associated with Fraxinus Pennsylvanica Marshall (Oleaceae) in the Red River Valley of Eastern North Dakota
(North Dakota State University, 2014)
The emerald ash borer (Agrilus planipennis; EAB) is an invasive wood-boring beetle causing mortality of ash trees in North America. This project was initiated because of the threat of EAB moving into North Dakota. The main ...
Association and Bioavailability of 17β-Estradiol with Soil and Manure Aqueous Dissolved and Colloidal Fractions
(North Dakota State University, 2014)
Steroidal estrogens in the environment exert toxicological effects at very low concentrations. Furthermore, dissolved and colloidal fractions of soil and manure play an important role in the environmental fate and transport ...
Yield and Quality Prediction Using Satellite Passive Imagery and Ground-Based Active Optical Sensors in Sugar Beet, Spring Wheat, Corn, and Sunflower
(North Dakota State University, 2014)
Remote sensing is one possible approach for improving crop nitrogen use efficiency to save fertilizer costs, reduce environmental pollution, and improve crop yield and quality. Feasibility and potential of using remote ...
Exploring Effects of Weed Management in Agroecosystems: Arthropods, Soil Properties and Soybean Production
(North Dakota State University, 2014)
Soil-dwelling arthropods contribute to agroecosystems, but it’s unclear how specific taxa respond to weed management practices. Objectives were to explore 1) response of Collembola to weed management in a glyphosate-tolerant ...
Plant Community Composition of Camp Grafton Training Center (South Unit) from 1998-2013
(North Dakota State University, 2014)
A vegetation monitoring study was conducted from 1998 to 2013 at Camp Grafton South (CGS) in Eddy County, North Dakota to assess how climatic, grazing, and military training disturbance affects plant community composition. ...
Sodic Soil Swelling and Dispersion and their Implications for Water Movement and Management
(North Dakota State University, 2014)
North Dakota has over 1.9 million ha of sodium-affected soils, influencing water movement and crop production. This dissertation consists of four studies examining different aspects of sodic soils. The first study surveys ...
Driver Attitudes and Crash Patterns in Western North Dakota Oil Counties: Links between Perceptions and Reality
(North Dakota State University, 2014)
Traffic safety conditions in the 17-county oil region of western North Dakota have changed considerably in recent years. Roads previously used for low-volume, agricultural purposes are presently utilized at high volumes ...
Drying and Pretreatments Affect the Nutritional and Sensory Quality of Oyster Mushrooms
(North Dakota State University, 2014)
The effect two drying treatments (solar and oven), three blanching treatments (no blanching, water and steam), and four chemical treatments (no chemical, lemon juice, vinegar and potassium bisulfite) on oyster mushroom ...
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 ...
Winter Wheat Management for Improving Soil Quality and Reducing Greenhouse Gas Emissions
(North Dakota State University, 2014)
Carbon dioxide (CO2) and nitrous oxide (N2O) concentrations in the atmosphere have greatly increased in recent times. Intensive agricultural practices, combustion of fossil fuels, deforestation, and wetland drainage have ...
