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)
