Application Of Drainage Water Management And Saturated Buffers For Conservation Drainage In South Dakota, Abhinav Sharma Jan 2018

Application Of Drainage Water Management And Saturated Buffers For Conservation Drainage In South Dakota, Abhinav Sharma

Electronic Theses and Dissertations

Edge of field practices such as drainage water management (DWM) and saturated buffers can reduce nutrient transport from croplands to surface waterbodies. DWM uses stackable weir boards in a control structure to manipulate the water table depth throughout the cropping season and reduce the amount of nutrient rich water draining out from the field. Saturated buffers, on the other hand, use a control structure to divert water draining out from the cropland to a vegetative strip via a subsurface tile installed parallel to a waterway. For the saturated buffer systems, a combination of natural denitrification, nitrogen mineralization, and plant uptake …

Development Of Vegetation Mapping With Deep Convolutional Neural Network, Sae-Han Suh Jan 2018

Development Of Vegetation Mapping With Deep Convolutional Neural Network, Sae-Han Suh

Electronic Theses and Dissertations

The Precision Agriculture plays a crucial part in the agricultural industry about improving the decision-making process. It aims to optimally allocate the resources to maintain the sustainable productivity of farmland and reduce the use of chemical compounds. [17] However, the on-site inspection of vegetations often falls to researchers’ trained eye and experience, when it deals with the identification of the non-crop vegetations. Deep Convolution Neural Network (CNN) can be deployed to mitigate the cost of manual classification. Although CNN outperforms the other traditional classifiers, such as Support Vector Machine, it is still in question whether CNN can be deployable in …

Measuring The Influence Of Bedding On Soil Nitrogen Losses And Corn Crop Nitrogen Characteristics For Fall Applied Solid Beef Cattle Manure In Eastern South Dakota, Mukesh Mehata Jan 2018

Measuring The Influence Of Bedding On Soil Nitrogen Losses And Corn Crop Nitrogen Characteristics For Fall Applied Solid Beef Cattle Manure In Eastern South Dakota, Mukesh Mehata

Electronic Theses and Dissertations

Nitrogen (N) is a major component of chlorophyll which plays a key role in the photosynthesis process in crops. The N is one of the highest demanded nutrients by all plants for their growth and reproduction. Manure or inorganic fertilizer is often applied to fulfill the crops’ N demand. However, the applied N sources have the potential of N losses in different forms from the soil volume in many ways such as ammonia (NH3) volatilization, aerial nitrous oxide (N2O) loss, nitrate (NO3 --N) leaching, and runoff and/or erosion. Soil fertility, crop yield, water quality, and …

Evaluating E. Coli Particle Attachment And The Impact On Transport During High Flows, Louis Amegbletor Jan 2018

Evaluating E. Coli Particle Attachment And The Impact On Transport During High Flows, Louis Amegbletor

Electronic Theses and Dissertations

Fecal indicator bacteria, including E. coli, are the leading cause of water quality impairments within assessed waters in the United States. The source of E. coli includes WWTP, leaking sewers, animal manure, wildlife, livestock, and stream bed sediment. Storm events contribute to bacteria loading within waters through wash-in of land sources of bacteria and resuspension of bacteria within sediments. Bacteria introduced into the water column are either attached to particles or are unattached (or free-living). The goal of this study was to examine the attachment of E. coli to different particle sizes, including their impact on contributing to water …

Development Of An Odor Management Plan For South Dakota, Suraiya Akter Jan 2018

Development Of An Odor Management Plan For South Dakota, Suraiya Akter

Electronic Theses and Dissertations

Odor from livestock operations is often a nuisance to the neighborhood stakeholders and is one of the major environmental and societal issues associated with livestock industries. An odor management plan is not a requirement during the state permitting process of any livestock operation in South Dakota, but may be required to varying degrees for county level approval. Some neighboring states have developed odor management planning guides or templates which help address odor issues. Adoption of an odor management plan in SD can help address concerns of odor for the continuously expanding livestock industry in this state. Hence, an odor management …

A Quantitative Environmental Assessment Of Incorporating Torrefaction Into Farming Enterprises In Eastern South Dakota, Dinesh Fuyal Jan 2018

A Quantitative Environmental Assessment Of Incorporating Torrefaction Into Farming Enterprises In Eastern South Dakota, Dinesh Fuyal

Electronic Theses and Dissertations

The use of renewable energy sources has been increasing in the recent years due to population growth and environmental concerns. Biomass is a promising energy source that can be used to produce biofuels or torrefied pellets. Torrefied biomass may be used in power plants, industrial and residential heating, feedstocks for gasification, air and water filtrating, and soil amendment. The interest of torrefied pellets as energy sources for various applications has been increased in the recent years due to the concerns about energy security and environmental issues. This study focuses on the economic and environmental assessment of agricultural feedstocks like corn …

Effects Of Yogurt Fortification With Different Legumes Protein On The Physio-Chemical, Microbiological, And Rheological Properties, Prachi Pahariya Jan 2018

Effects Of Yogurt Fortification With Different Legumes Protein On The Physio-Chemical, Microbiological, And Rheological Properties, Prachi Pahariya

Electronic Theses and Dissertations

Nowadays, yogurt (a nutritious fermented dairy product) is getting popular around all over the world due to beneficial action provided by bacteria present in yogurt culture. Along with that, diet plans, which are high in protein and low in fat, has become appealing for growing healthy conscious population that makes a huge shift toward plantbased protein consumption. Therefore, the main objective of this research was to study the effects of yogurt fortification with extracted protein of different beans (legumes)- pinto and kidney beans on the physio-chemical (Moisture, Fat, Protein, Ash, Total Solids Content (TSC), pH, Titratable Acidity (TA), Water Holding …

Development Of Polylactic Acid (Pla)-Based Nanocomposite Films For Smart Food Packaging Applications, Zeyad Albahr Jan 2018

Development Of Polylactic Acid (Pla)-Based Nanocomposite Films For Smart Food Packaging Applications, Zeyad Albahr

Electronic Theses and Dissertations

Most of current food packaging resources are non-renewable and nonbiodegradable. The use of these materials has resulted in serious environmental issues. In recent years, the recognition of waste disposal problems and their impacts on the environment has risen the demand for packaging manufactured from renewable materials. However, there are some limitations of using biopolymers for food packaging applications. These limitations include unreliable mechanical and barrier properties. These issues may be addressed by combining biopolymers and nanotechnologies. Nanotechnologies are expected to improve the performance of biopolymer-based packaging materials for food packaging applications. Cellulose nanocrystals (CNC) has shown a potential to be …
