Anaerobic Co-digestion of Dairy Manure with Canola Meal
(North Dakota State University, 2011)There has been an increase of confined animal feeding operations (CAFOs) generating large amounts of manure. When this manure is not handled properly, it generates greenhouse gases (GHGs), odors and water pollution. ... -
Application of SWAT for Impact Analysis of Subsurface Drainage on Streamflows in a Snow Dominated Watershed
(North Dakota State University, 2011)The wet weather pattern since the early 1990's has created two problems for the people living in the Red River Valley (RRV): (1) wet field conditions for farmers and (2) more frequent major spring floods in the Red River ... -
Bioavailability and Biodegradability of Dissolved Organic Nitrogen Originated From Municipal and Animal Wastewater
(North Dakota State University, 2015)Due to the increased concern on dissolved organic nitrogen (DON) in surface waters, it is necessary to understand the biodegradability and bioavailability of DON in point and non-point sources. In this study, algae and ... -
Characterization of Biochar from Different Feedstocks under Low and High Temperature and Their Effects on Greenhouse Gas Emission and Ammonia Volatilazation from Soil Incubation
(North Dakota State University, 2020)Biochar is a potential soil amendment that likely to reduce GHG emissions from land application to soil, but their properties depend on biomass types and pyrolysis temperature. In this study, biochars were produced from ... -
Combined Effect of Densification and Pretreatment on Cellulosic Ethanol Production
(North Dakota State University, 2012)Biomass densification enhances material stability, improves flowability, and decreases both handling and transportation costs. The effect of densification, before or after pretreatment, was tested to determine the effect ... -
Developing a New Powered Seed Delivery System with Constant Seed Release Speed Using Two Confronting Belts
(North Dakota State University, 2018)Seed delivery devices are aimed to carry seeds down to open furrow that might affect uniformity of plant stand and spacing. The objective of this study was to develop and evaluate a new seed delivery system utilizing a ... -
Effect of Water Table Level on Soybean Water Use, Growth and Yield Parameters
(North Dakota State University, 2018)Responses of soybean (Glycine max) water uptake and crop growth to four constant water table depths (30, 50, 70, and 90 cm) were studied under a controlled environment using lysimeters. Additionally, control lysimeters ... -
Efficacy and Recovery of Cellulases Immobilized on Polymer Brushes Grafted on Silica Nanoparticles
(North Dakota State University, 2014)Cellulosic biofuels can be more economical if cellulases are recovered and reused. Cellulase and β-glucosidase were immobilized on poly(acrylic acid) brush particles. Impact of brush enzyme density on efficacy and recovery ... -
Evaluating Standard Wet Chemistry Techniques and NIR Spectroscopic Models for Determining Composition and Potential Ethanol Yields of Multi-Species Herbaceous Bioenergy Crops
(North Dakota State University, 2011)Herbaceous perennials represent a considerable portion of potential biomass feedstocks available for the growing bioenergy industry. Their chemical composition and biomass yields, which are important in determining ethanol ... -
Evaluation of Storage Techniques to Preserve Fermentable Sugars from Sugar Beets for Ethanol Production
(North Dakota State University, 2012)New sugar beet varieties may qualify as an advanced biofuel feedstock in the U.S., but new alternatives to conventional pile storage are necessary to preserve fermentable sugars and allow yearlong beet ethanol production. ... -
Extracting Carotenoids from Corn Industry Coproducts
(North Dakota State University, 2016)Two experiments were completed to develop methods for extracting xanthophylls from corn industry co-products, post fermentation (PF) corn oil and corn gluten meal (CGM). A solid phase extraction (SPE) method was used to ... -
A Field Study on LiDAR Sensor for Unmanned Ground Vehicle Navigation Application in Precision Agriculture
(North Dakota State University, 2022)LiDAR sensor’s mapping and detection abilities make these sensors an important tool for research on navigation and object detection for robots and vehicles. This study used a ground robot and LiDAR sensor to collect ... -
Implementing High-Throughput Phenotyping at the NDSU Dry Bean (Phaseolus vulgaris l.) Breeding Program Using Unmanned Aerial Systems
(North Dakota State University, 2021)Plant breeding has led to considerable yield gains to several crops. However, it alone might not be able to keep up with the growing demand for food. In this study, data extracted from UAS-collected RGB and multispectral ... -
Incorporation of Subsurface Drainage and Subirrigation Into the Checkbook Method
(North Dakota State University, 2016)The highly variable climate of the Red River Valley of the North brings both flood and drought conditions, leading to an interest in subsurface water management systems (WMS). These subsurface WMS can drain excess water ... -
Increased Oil Recovery from Distillers Dried Grains with Solubles and Whole Stillage
(North Dakota State University, 2020)Finding a viable method to recover oil from the corn ethanol industry's co-products has considerable economic prospects for ethanol bio-refineries. This study examined the effects of enzymes and ethanol on oil recovery ... -
Infield Biomass Bales Aggregation Logistics and Equipment Track Impacted Area Evaluation
(North Dakota State University, 2017)Efficient bale stack location, infield bale logistics, and equipment track impacted area were conducted in three different studies using simulation in R. Even though the geometric median produced the best logistics, among ... -
Machine Vision Methods for Evaluating Plant Stand Count and Weed Classification Using Open-Source Platforms
