From Seed To Harvest: A Comparative Life Cycle Assessment Of Conventional Vs. Organic Cotton Agriculture, Rebecca Hoehn
From Seed To Harvest: A Comparative Life Cycle Assessment Of Conventional Vs. Organic Cotton Agriculture, Rebecca Hoehn
Masters Theses, 2010-2019
Conventional and organic cotton farming practices both have benefits and detriments to each type. Cotton agriculture is responsible for the use of a third of the agriculture industries’ pesticide use. In order to help alleviate the use of pesticide dependency the following study reviews the use of pesticides as well as other stressors of both systems and hopes to decide how sustainable agriculture in the cotton industry can be attained. Evaluations of both systems have been compared in order to reach the decisions of sustainability.

Assessment Of Ruminal Fermentation Characteristics Of Condensed Tannin-Containing Forages Using Continuous Cultures, Christina Marie Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two independent studies were conducted to assess the effects of feeding condensed tannin (CT)-containing forages to continuous cultures to evaluate their impacts on ruminal fermentation and digestibility, with an emphasis on methane (CH4) and ammonia-N (NH3-N) production. In Chapter 3, treatments consisted of: 1) 100% alfalfa hay (AH), 2) 50% AH and 50% birdsfoot trefoil hay (dry matter (DM) basis; AHBFTH), and 3) 100% birdsfoot trefoil hay (BFTH). Three replicated runs lasted 8 d each, with the first 5 d allowed for microbial adaptation to the diets, and 3 d for data collection and sampling. Methane, neutral detergent fiber (NDF) …
Land Use As It Relates To Land Slope, James D. Plourde, Bryan C. Pijanowski
Land Use As It Relates To Land Slope, James D. Plourde, Bryan C. Pijanowski
GIS Day
The goal of this project is to analyze the relationship between the slope of land and agricultural land use. The output was analyzed to determine a threshold point at which agriculture practices drop off in relation to higher slope values. Slope of the land is important to agricultural practices because it impacts drainage and net crop primary production. Agricultural land was extracted from the 2001 National Land Cover Dataset using reclassification tools in ArcGIS 9.3. The slope of the contiguous United States was derived from the United States Geological Survey National Elevation Dataset by using the slope tool in the …

Foodshed Foundations: Law's Role In Shaping Our Food System's Future, Margaret Sova Mccabe
Foodshed Foundations: Law's Role In Shaping Our Food System's Future, Margaret Sova Mccabe
Law Faculty Scholarship
[. . .] This symposium Article analyzes how we can rethink the architecture of law based on a foodshed model to provide a greater role for local, state, and regional government in the American food system. In turn, greater roles for different levels of government may help America achieve greater efficiencies in domestic food safety, nutrition and related public health issues, sustainability, and international trade.
Americans need a greater voice in the food system. The foodshed model is a powerful vehicle that allows us to conceptualize change, allowing greater citizen participation and a more nuanced approach to food policy. The …

Evapotranspiration Of Kentucky Bluegrass, Lynda L. Fenton
Evapotranspiration Of Kentucky Bluegrass, Lynda L. Fenton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Rapid population growth in arid regions of the western US is placing increased demand on water resources. Variability in precipitation and common occurrence of drought have promoted scrutiny of water use in urban lawns and gardens. However, few reliable measurements of water use of these landscapes exist. Quantifying the amount of water used vs. required by landscapes such as turfgrass would allow significant water conservation. Evapotranspiration (ET) is affected by biophysical factors such as: available energy, turbulent mixing, saturation deficit, soil water, and stomatal conductance. In order to simulate the water use by turfgrass, the relative importance of these processes …

Evaluation Of Semiochemical Strategies For The Protection Of Whitebark Pine Stands Against Mountain Pine Beetle Attack Within The Greater Yellowstone Ecosystem, Greta Katherine Schen-Langenheim
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
High-dose verbenone, verbenone plus nonhost volatiles (NHVs), and both semiochemicals in combination with aggregant-baited funnel traps were tested for stand- level protection against mountain pine beetle attack for two consecutive years (2004-2005) at three seral high elevation whitebark pine sites in the Greater Yellowstone Ecosystem. In 2004, two 0.25-hectare treatments comprised of 25 high-dose verbenone pouches or verbenone pouches combined with single baited funnel traps were tested in a push-pull strategy. In 2005, 25 high-dose verbenone and 25 NHV pouches, or verbenone and NHV in combination with baited funnel trap clusters were tested. In both years, treatments were compared to …
Physiological And Molecular Function Of Hap3b In Flowering Time Regulation And Cold Stress Response, Mingxiang Liang
Physiological And Molecular Function Of Hap3b In Flowering Time Regulation And Cold Stress Response, Mingxiang Liang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Heme-activated proteins (HAPs) are transcription factors that have multiple roles in plant growth and development, such as embryogenesis, flowering time control, and drought tolerance.
In the present study I found that HAP3b was also involved in controlling response to cold stress. Transcript profiling and gene expression analyses indicated that HAP3b repressed the CBF3 regulon under normal growth conditions. As a result, plants with HAP3b-overexpressed showed decreased survival rates while plants homozygous for the null allele hap3b showed an improved freezing tolerance compared to wild-type plants.
To understand the mechanism of HAP3b in Arabidopsis, i.e. whether it also acts …
The Influence Of Collective Action And Policy In The Development Of Local Food Systems, Lori Porreca
The Influence Of Collective Action And Policy In The Development Of Local Food Systems, Lori Porreca
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The modern global agrifood system has had significant negative impacts on consumers and producers. This has precipitated the rise of local food systems that are purported to improve the health and livelihoods of consumers and producers. High expectations have led to significant public and private resources dedicated to the development of local food systems. Despite this, there has been little systematic research exploring the social and institutional conditions that facilitate or frustrate local food system development.
Using a comparative case study approach, this study explored the ways local structural conditions, collective action, food system policies, and the political context affect …
Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson
Cellulosic Ethanol: The Benifits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson
Department of Environmental Studies: Undergraduate Student Theses
Abstract Ethanol is a biofuel that has unique capabilities to mitigate global climate change by reducing greenhouse gas emissions while simultaneously supporting rural economies and decreasing the United States’ dependence on foreign oil. Currently, the state of Nebraska depends on corn ethanol, which may be unsustainable. Cellulosic ethanol is a promising alternative but it is not without its problems, including high production costs and potential environmental damage. This thesis is an attempt to understand the benefits, downfalls, and processes of corn-based and cellulosic ethanol and the potential implications to Nebraska. This research should shed some light on the current obstacles …

The Future Of Southern Agriculture, Gregory Keith Bartley Jr.
The Future Of Southern Agriculture, Gregory Keith Bartley Jr.
Gregory Keith Bartley Jr.
The increasing demand for the supply of energy in the south heavily impacts the allocation of water for use in agriculture. With such a high percentage of the south's freshwater going towards energy production, little can make its way into food, feed, and fiber. Because the need for this exponential energy production in the south is currently greater than its agricultural importance, southern farmers are left to endure heavy irrigation restrictions. The solution to this problem can manifest itself in one of two ways. Southern states can either implement strategies that can reduce plant water consumption without reducing yield, or …

Effects Of Changes In Agriculture And Abundance Of Snow Geese On Carrying Capacity Of Sandhill Cranes During Spring, Aaron T. Pearse, Gary L. Krapu, David A. Brandt
Effects Of Changes In Agriculture And Abundance Of Snow Geese On Carrying Capacity Of Sandhill Cranes During Spring, Aaron T. Pearse, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
The Central Platte River Valley (CPRV) in Nebraska is a key spring staging area for approximately 80% of the midcontinent population of sandhill cranes (Grus canadensis). Evidence that cranes currently are acquiring fat less efficiently than in the past along with a large increase in use of the CPRVby snow geese (Chen caerulescens) led us to evaluate waste-corn availability and index spatial and temporal variation in abundance of sandhill cranes and waterfowl using the CPRV. We also developed a predictive model to assess impact of changes in availability of corn under past, present, and potential future conditions. Predicted …
