Long-Term Residue And Water Management Effects On Soil Respiration And Soil Aggregate Stability In A Wheat-Soybean, Double-Crop System In Eastern Arkansas, Sharon Faye Smith
Long-Term Residue And Water Management Effects On Soil Respiration And Soil Aggregate Stability In A Wheat-Soybean, Double-Crop System In Eastern Arkansas, Sharon Faye Smith
Graduate Theses and Dissertations
Sustainability in agriculture is paramount to assuring continued production from our most naturally fertile soils. Storing carbon (C) in soil as organic matter through sustainable agricultural management practices can both remove atmospheric C and improve soil quality. The objective of this study was to evaluate the long-term effects of water management (irrigation and dryland), residue management [burn and no-burn, conventional (CT) and no-tillage (NT)] and residue/fertility level (high and low) on soil respiration and aggregate stability in a wheat- (Triticum aestivum L.) soybean [Glycine max (L.) Merr.], double-crop system in a silt-loam soil (Aquic Fraglossudalf) in the Mississippi River Delta …
A Roadmap To Mindful Consumption Through Informative Labeling Practices: The Effects Of Sustainability Disclosure Formats On Consumer Product Evaluations, Yoon-Na Cho
Graduate Theses and Dissertations
Despite the interest of consumers in sustainable and environmentally friendly products, only a limited number of studies have focused on sustainability level disclosures for consumer packaged goods. The general overarching purpose of this dissertation is to extend the internal reference point and information processing literatures to better understand how consumers will process sustainability disclosures. Applying the theoretical lens of assimilation bias in conjunction with self-enhancement offers an important extension to prior work. Across two retail lab studies and four online experiments, I demonstrate that the perceived sustainability utility (i.e., the difference between a specific brand's level of sustainability and category-level …
Evaluation Of Water Sanitation Options For Poultry Production, Pramir Maharjan
Evaluation Of Water Sanitation Options For Poultry Production, Pramir Maharjan
Graduate Theses and Dissertations
An evaluation of poultry farm water supplies was conducted to determine the value and impact of water system sanitation practices in commercial broiler houses on microbial levels. Water line cleaning between flocks using concentrated disinfectant solution before placing chicks reduced biofilms retained in the lines to a safe level. Occasional microbial surges were noticed during different points of flock grow-out period even when daily water sanitation was present indicating water is highly susceptible to microbial contamination. However, the daily water sanitation practice controlled the occasional microbial surges in water from sustaining and kept drinking water to a microbiologically acceptable level. …
The Use Of Non-Traditional Technologies To Improve The Efficiency And Sustainability Of Modern Poultry Production, Christopher Pixley
The Use Of Non-Traditional Technologies To Improve The Efficiency And Sustainability Of Modern Poultry Production, Christopher Pixley
Graduate Theses and Dissertations
Historically, major driving factors for the animal agriculture industry have been efficiency and profitability. As demand for efficient food production has increased, the industry has focused research efforts on ways to improve the rearing process. Current market demands are requiring the industry to abandon some of the traditional tools it has used to maximize productivity. However, developing alternative technologies are available which may fill the void. Unfortunately, these alternatives are less well-described and the beneficial impacts they can have are not fully understood. As the animal agriculture industry matures it is becoming evident that consumers will continue to demand methods …
Modeling Greenhouse Gas Emissions And Net Return Implications For Cow-Calf Producers In The Ozark Highlands, Stephen Aaron Smith
Modeling Greenhouse Gas Emissions And Net Return Implications For Cow-Calf Producers In The Ozark Highlands, Stephen Aaron Smith
Graduate Theses and Dissertations
Cow-calf producers in the Ozark Highlands region are under continuous pressure to improve economic efficiency. Additionally, estimating greenhouse gas (GHG) emissions from cow-calf and forage production processes may become increasingly important as policy makers seek to mitigate or reduce agriculture's role in climate change. As such, this analysis had three objectives. Objective 1: Provide a model that could be used by cow-calf producers, extension agents, and researchers to evaluate GHG and net return (NR) repercussions when modifying site characteristics, production methods, and inputs. Objective 2: Develop a user guide such that the methodology for estimating cow-calf GHG emissions and NR …
