Wetland Restoration Techniques and Associated Costs in Southeastern North Dakota
(North Dakota State University, 2015)
Degraded wetlands are a common occurrence throughout the Prairie Pothole Region of the United States. Many restoration attempts have been conducted to restore these unique ecosystems to their previous conditions. However, ...
Density and Movement of Soybean Aphid, Aphis Glycines (Hemiptra: Aphididae) in Response to Temperature and Resistant Soybean Plants
(North Dakota State University, 2012)
Movement is one way herbivores respond to their host plant, yet the movement of relatively immobile insects has received little attention. We studied how the movement and density of apterous soybean aphids responds to a ...
Crop Price and Land Use Change: Forecasting Response of Major Crops Acreage to Price and Economic Variables in North Dakota
(North Dakota State University, 2015)
The objective of this study is to examine land use change for cropping systems in North Dakota. Using Seemingly Unrelated Regression with full information maximum likelihood estimation method, acreage forecasting models ...
Pollinator Response to Annual Forb Plantings and Self-Pollinating Dry Bean Crops in Agroecosystems
(North Dakota State University, 2021)
Intensive agricultural systems have had several ecological effects on the surrounding ecosystem, including contributing to widespread pollinator declines. In order to help supplement bee communities and potentially improve ...
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 ...
Effects of Sediment Removal on Vegetation Communities in Prairie Pothole Wetlands in North Dakota
(North Dakota State University, 2011)
The goal of this study was to assess effects of sediment removal on vegetation communities in Prairie Pothole wetlands in North Dakota to determine if this management technique is providing desired results to create ...
Brine-Contaminated Soils in Western North Dakota: Site Assessment Methodology and a New In-Situ Remediation Method
(North Dakota State University, 2016)
Anthropogenic soil salinity caused by produced water (i.e., brine) contamination is an issue in all oil and gas producing regions. The objectives of this research are to develop soil electrical conductivity (EC) conversion ...
Relationship of Vegetation Indices from Drone-Based Passive Optical Sensors with Corn Grain Yield and Sugar Beet Root Yield and Quality
(North Dakota State University, 2019)
The main goal of this study was to calibrate small unmanned aircraft system (SUAS) based vegetation indices with fertilizer-N application rate and yield for corn and sugar beet. It was hypothesized that canopy reflectance ...
Invasions in the Prairie Pothole Region: Addressing the Effects of Exotic Plants on Wetland and Grassland Ecosystems and Restoration Efforts
(North Dakota State University, 2020)
Three wetland restoration methods: seeding, seeding + hay mulch, and seeding + hay mulch + vegetation plugs were compared via the plant community within a formerly cropped wetland in southeastern North Dakota. Arrangement ...
Effects of Grazing of Reed Canarygrass (Phalaris arundinacea) in Restored Wet Meadows in the Northern Tall Grass Prairie
(North Dakota State University, 2019)
Reed canarygrass (Phalaris arundinacea) is a grass species that can dominate wet meadow plant communities. This study investigated if grazing by cattle on restored wet meadows suppresses reed canarygrass, thereby promoting ...
