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, ...
Belowground Bud Banks of Native, Perennial Grasses and Interactions with Fire in the Northern Great Plains
(North Dakota State University, 2013)
Mixed-grass prairies of the northern Great Plains evolved following frequent disturbances such as drought, fire, and extensive grazing by ungulates. As a result of periodic natural disturbances, native grass reproductive ...
An Exploration of the Effects of Cattle Grazing, Prairie Dog Activity, and Ecological Site on Plant Community Composition and Western Wheatgrass Vegetative Reproduction in Northern Mixed Grass Prairie
(North Dakota State University, 2017)
Modern range scientists and managers are tasked with feeding more people than ever before while maintaining or improving the ecological function of over half of the world’s land surface. Often, these tasks are in conflict. ...
Driver Attitudes and Crash Patterns in Western North Dakota Oil Counties: Links between Perceptions and Reality

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 ...
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, ...
Irrigated Potato (Solanum Tuberosum L.) Yield, Quality Response and Nitrogen Losses as Influenced by Nitrogen Fertilizer Management and Cultivars
(North Dakota State University, 2017)
Field studies were conducted in 2015 and 2016 growing season at Northern Plains Potato Growers’ Association Irrigation site near Inkster, ND to evaluate the effectiveness of enhanced efficiency fertilizers (EEFs) in ...
Method Selection and Estimating Densities for Grassland Butterflies in the Mixed-Grass Prairie
(North Dakota State University, 2018)
Grassland butterflies contribute to the larger group of pollinating insects that are vital for continued plant production and food security in agroecosystems. However, grassland butterflies, along with overall biodiversity, ...
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 ...
