Soil Function Following Remediation Using Ex Situ Thermal Desorption
(North Dakota State University, 2017)
Soils perform many functions essential to human and ecosystem health, and contamination by organic compounds diminishes the ability of the soil to perform those functions. One method for remediating contaminated soils is ...
Nitrogen Dynamics in Soils from the Red River Valley of the North
(North Dakota State University, 2015)
The objectives of this study were to evaluate the effects of (i) N management on crop yield, N availability, and N losses from a silty clay having subsurface drainage, (ii) soil moisture and nitrification inhibitor nitrapyrin ...
Geographic Distribution and Effects of Transgenic Corn Hybrids and Chemical Insecticides on Northern and Western Corn Rootworms (Coleoptera: Chrysomelidae) in North Dakota
(North Dakota State University, 2018)
Northern (Diabrotica barberi Smith & Lawrence) and western (D. virgifera virgifera LeConte) corn rootworms are major corn (Zea mays L.) pests in North America. Integrated pest management (IPM) strategies used for corn ...
Above and Belowground Effects of Nutrient Applications and Mowing Treatments on Restored North Dakota Grasslands
(North Dakota State University, 2015)
Although more than half of the annual production within North American grasslands occurs beneath the soil surface, this portion is oftentimes overlooked in ecological studies. In this study, we investigated the above- and ...
Smooth Brome (Bromus Inermis) Phenology in the Northern Tallgrass Prairie
(North Dakota State University, 2018)
Smooth brome (Bromus inermis) invasion into tallgrass prairie has led to development of methods of control. Prescribed burning is used by the US Fish and Wildlife Service (USFWS) to manage prairie according to a provisional ...
Economic and Social Impacts of Rapid Shale Oil Development in Western North Dakota
(North Dakota State University, 2016)
This dissertation comprises of five qualitative and exploratory studies. The studies focus
on the social and economic impacts of rapid shale oil development, which is colloquially referred
to as an “oil boom” on the ...
Advancing Soil Health: Linking Belowground Microbial Processes to Aboveground Land Management
(North Dakota State University, 2016)
Advancing soil health lies at the intersection of belowground microbial processes and aboveground land management. However, linking microbial processes to land use is difficult. Understanding the response of soil microbes ...
Symbiotic Nitrogen Fixation in Dry Bean Cultivars
(North Dakota State University, 2018)
Dry Beans (Phaseolus vulgaris L.), is the second-most important grain legume, and North Dakota has ranked first in dry bean production. The overarching research question of my project is whether we can increase the nitrogen ...
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 ...
Wetland Assessment and Nutrient Dynamics in North Dakota
(North Dakota State University, 2013)
Wetlands provide a variety of services and functions. Studies have highlighted the importance of wetlands in water purification, groundwater replenishment, flood control, sediment and nutrient retention and export, ...
