Advanced Evapotranspiration Measurement for Crop Water Management in the Red River Valley
(North Dakota State University, 2019)As the main component of terrestrial energy and water balance, evapotranspiration (ET) moves a large amount of water and energy in the form of latent heat flux from bare soil and vegetated surfaces into the atmosphere. ... -
Agricultural Field Applications of Digital Image Processing Using an Open Source ImageJ Platform
(North Dakota State University, 2019)Digital image processing is one of the potential technologies used in precision agriculture to gather information, such as seed emergence, plant health, and phenology from the digital images. Despite its potential, the ... -
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 Nanoparticles in Livestock Manure for Understanding Hydrogen Sulfide and Greenhouse Gas Reduction Mechanism
(North Dakota State University, 2018)The agricultural sector is one of the sources of greenhouse gases (GHGs) emission, especially methane (CH4), and contributing approximately 250 million metric ton carbon dioxide (CO2) equivalent emission per year. Almost ... -
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 ... -
Design and Development of an Automatic Steering System for Agricultural Towed Implements
(North Dakota State University, 2022)While an auto steered tractor can improve the overall accuracy and efficiency of an operation, for operations that involve towing an implement, a significant portion of the efficiency reduction comes from uncontrolled ... -
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 ... -
Effects of Calcium Based Surface Amendments on Hydraulic Conductivity and Selected Physical Properties of Subsurface Drained Sodic Soils
(North Dakota State University, 2016)Managing excess soil water in agricultural fields in the Northern Great Plains through subsurface drainage increases the risk of sodification in high-risk soils. Leaching sodic soils with low electrical conductivity (EC) ... -
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 ... -
