Suppressing Canada Thistle Establishment with Native Seed Mixes and Resulting Cost Analysis
(North Dakota State University, 2013)
Canada thistle (Cirsium arvense) on conservation lands is costly and diminishes conservation objectives. This project was designed to control Canada thistle by spiking native seed mixtures. Spiking is where a native seed ...
The Influence of Soil Salinity Gradients on Soybean [Glycine Max (L.) Merr.] and Corn (Zea Mays L.) Growth
(North Dakota State University, 2015)
An estimated 2.3 million hectares are salt-affected in North Dakota (Brennan and Ulmer,
2010), a number increasing due to land management, climate, and crop choice. As a result, yield
reductions are noted for salt-sensitive ...
Foliar Application of Iron Chelated Fertilizer and Surfactants for Management of Iron Deficiency Chlorosis in Soybeans
(North Dakota State University, 2016)
Iron deficiency chlorosis (IDC) is a production challenge for farmers growing soybeans
[Glycine max (L.) Merr.], especially in the Red River Valley. It is critical to correct this
deficiency as soon as symptoms arise before ...
Evaluation of Alternative Methods for Leafy Spurge Control in the Northern Great Plains
(North Dakota State University, 2018)
Leafy spurge (Euphorbia esula L.) is a costly noxious weed to manage in the Northern Great Plains; it invades rangelands and displaces native and desirable vegetation. Our first objective was to test the recommended full ...
Biological Response to Sulfate Salinity in Richland County, North Dakota
(North Dakota State University, 2016)
Soil salinization is a major threat to agricultural ecosystems. Consequently, an understanding of agro-ecosystem functions affected by increasing levels of soil salinity is critical for land management. The purpose of this ...
Weed Control Effects on Native Species, Soil Seedbank Change, and Biofuel Production
(North Dakota State University, 2011)
Aphthona spp. flea beetles were released in the Little Missouri National Grasslands
(LMNG) in western North Dakota in 1999 to control leafy spurge (Euphorbia esula L.). The
changes in soil seed bank composition and leafy ...
Using Lidar Derived Information for Predicting Beaver Dam Site Selection at Mingo National Wildlife Refuge
(North Dakota State University, 2012)
Characterizing features that influence beaver (Castor Canadensis) to select a site to construct a dam may have important implications for managing damage to select stands of bottomland hardwood forest by beaver activity. ...
Monitoring the Effects of Surface Coal-Mine-Reclamation on Soil Biological Properties
(North Dakota State University, 2019)
Surface coal mining is a large-scale disturbance that disrupts soil properties that requires reclamation. Reclamation monitoring and success typically focuses on vegetation communities, but soil monitoring may improve our ...
Investigating the Influence of Grazing Management Practices on Pollinators to Inform Biodiversity Conservation in Working Grassland-Landscapes
(North Dakota State University, 2017)
Declines in pollinator populations worldwide are threatening pollination that supports native plant communities and global food production. Mitigating these impacts will require conservation actions that promote biodiversity ...
Association and Bioavailability of 17β-Estradiol with Soil and Manure Aqueous Dissolved and Colloidal Fractions
(North Dakota State University, 2014)
Steroidal estrogens in the environment exert toxicological effects at very low concentrations. Furthermore, dissolved and colloidal fractions of soil and manure play an important role in the environmental fate and transport ...
