Utilizing Annual Forages in a Single and Dual Crop System for Late-Season Grazing in Southcentral North Dakota
(North Dakota State University, 2012)
Utilizing annual forages to extend the grazing season can improve late-season forage production and quality, cow performance, and soil health; while providing a cost-effective alternative to drylot feeding. A four-year ...
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 ...
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. ...
Transferability of Regional and Wetland Specific Assessment Methods for a Statewide Approach
(North Dakota State University, 2012)
The transferability and expansion of current wetland assessment methods to other wetland classes and ecoregions throughout the state of North Dakota is the primary goal of this research. During the growing season of 2011, ...
Pest Management of Wheat Stem Sawfly, Cephus Cinctus Norton (Hymenoptera: Cephidae), in Western North Dakota
(North Dakota State University, 2012)
The wheat stem sawfly, Cephus cinctus Norton, is regarded as a major pest of dryland wheat in the Upper Great Plains. For peak emergence of wheat stem sawfly, the most accurate base was 0 C using air temperature, and then ...
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 ...
Impact of Nitrogen and Rhizobial Seed Inoculants on Soybean Aphid (Aphis Glycines Matsumura) Densities
(North Dakota State University, 2012)
Soybeans are able to obtain nitrogen from two different sources, nitrogen found in the soil (e.g. from fertilizers) and biologically fixed nitrogen (from symbiotic bacteria called rhizobia). Nitrogen source and degree of ...
Characterizing Soil Microbial Communities of Reclaimed Roads in North Dakota
(North Dakota State University, 2012)
Reclaimed roads on the Little Missouri National Grasslands of southwestern North Dakota have not returned to pre-disturbance conditions. Phospholipid fatty acid analysis was performed on soil samples collected from reclaimed ...
Prairie Dog (Cynomys Ludovicianus) Contributions to Soil Change on Grazed Mixed-Grass Prairie
(North Dakota State University, 2012)
Vegetation and soils were evaluated on a black-tailed prairie dog (Cynomys ludovicianus) colony and adjacent non-disturbed mixed-grass prairie in central South Dakota. The study’s objectives were 1) determine differences ...
Effectiveness of Multiple Restoration Techniques in Reducing the Abundance of Kentucky Bluegrass and Smooth Bromegrass in the Northern Great Plains
(North Dakota State University, 2012)
Kentucky bluegrass (Poa pratensis L.) and smooth bromegrass (Bromus inermus L.) are cool-season, perennial, non-native grasses that are invading North Dakota grasslands. Two studies evaluated different restoration techniques ...
