Discrimination of Leafy Spurge (Euphorbia esula L.) and Purple Loosestrife (Lythrum salicaria L.) Based on Field Spectral Data
(North Dakota State University, 2019)
Leafy spurge and purple loosestrife are noxious weeds that displace native vegetation.
Herbicides are often applied to these weeds during flowering, making it ideal to identify them
early in the season. This paper evaluates ...
Winter Feeding Beef Cattle: A Review on Bale Grazing in the Northern Great Plains
(North Dakota State University, 2019)
Bale grazing is a relatively unexplored winter feeding option for most beef cattle operations in the Northern Great Plains. Recently, several producers have been looking into using a bale grazing system for winter feeding ...
Fertilizer Management Strategies of Soybean (Glycine Max, L. Merrill) in Northcentral and Northwestern North Dakota
(North Dakota State University, 2019)
Soybean (Glycine max L. Merrill) is a new cash crop for north central and northwestern North Dakota producers. Soils and climate in these new soybean areas differ from those regions where the current fertilizer recommendations ...
Soil Biological Temporal Variability as Functions of Physiochemical States and Soil Disturbance
(North Dakota State University, 2019)
Within our ecosystems, soil biota control an array of functions, such as nutrient cycling and decomposition, and have been pursued as a soil quality indicator. Though microbial communities are known to be a reflection of ...
Influence of Neonicotinoid Seed Treatment on Two Co-Occuring Arthropod Pests, Two-Spotted Spider Mite (Tetranychus urticae) and Western Flower Thrips (Frankliniella occidentalis)
(North Dakota State University, 2019)
Insecticidal neonicotinoid seed treatments in agriculture is a common insect pest management strategy. Seed treatments have systemic and residual toxicity, which are effective against target insect pests. However, effects ...
A Study of Prairie Reconstructions in the Eastern Dakotas
(North Dakota State University, 2019)
Two studies of reconstruction processes in the Northern Great Plains (NGP) are presented. The first study is a retrospective study on United States Fish and Wildlife Service (USFWS) managed lands seeded with a high diversity ...
Chemical Repellents for Reducing Blackbird Damage on Mature Sunflowers: The Importance of Plant Structure and Avian Behavior in Field Applications
(North Dakota State University, 2019)
Across North America, blackbirds (Icteridae) depredate high-energy crops, such as sunflower (Helianthus annuus), placing an economic burden on producers. Chemically-defended crops, in the form of human-applied repellents, ...
Influences on Fungal Community Composition in Roots and Soil of Coffee and Other Rubiaceae in Costa Rica
(North Dakota State University, 2019)
Belowground fungi interact with plants directly as pathogens and mutualists, and indirectly as nutrient cyclers, yet the factors governing fungal community composition are poorly understood. Here I examined root and soil ...
Oil-Field Brine Impacts on Seed Germination and a Contemporary Remediation Technique for Contaminated Soils
(North Dakota State University, 2019)
The growth of fossil fuel production in North Dakota has resulted in numerous releases of brine. Brine releases cause vegetation mortality as well as the deterioration of soil structural and edaphic properties. Little ...
Riparian Graminoid Species Responses and Productivity in Compromised Environmental and Soil Conditions
(North Dakota State University, 2019)
Riparian buffers have been created as a sustainable and effective way to combat the harmful effects of excess nitrogen and soil salinity in riparian settings. The goal of this research was to determine what species will ...
