The Carbon Negative System: An Innovative System for Sustainable Community Development
(North Dakota State University, 2016)
It is understood civilization may be entering the Anthropocene Epoch, characterized by
human influences on Earth’s geology and environment. A growing body of literature highlights
the ecological concerns affiliated with ...
Vegetation and Fertilization Effects on Water Soluble Organic Carbon at Three North Dakota Sites
(North Dakota State University, 2012)
This study was initiated to better understand the role of WSOC in the process of sequestering carbon in mixed species grassland as compared to cropland systems. Previously established mixed-species grassland plot sites ...
Brine Impacted Soils in Semi-Arid Rangelands: Greenhouse Electrical Conductivity Thresholds and Ex Situ/In Situ Remediation Comparisons
(North Dakota State University, 2016)
Brine is a by-product of oil and gas extraction that can have profound impacts on soil chemistry and vegetation assemblages when discharged onto the soil surface. Brine spill remediation aims to remove or minimize the ...
The Relative Nitrogen Fixation Rate and Colonization of Arbuscular Mycorrhizal Fungi of Iron Deficient Soybeans
(North Dakota State University, 2011)
Soybeans (Glycine max L. Merr.) are a symbiont of two beneficial associations:
biological nitrogen fixation (BNF) with Bradyrhizobium japonicum, and arbuscular
mycorrhizal fungi (AMF). Within the Northern Great Plains ...
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 ...
