Master's Theses

ABSTRACT

Evaluating nanobubble-enriched water treatments for cleaning stainless steel winery tanks at the Gallo winery research station in Livingston, California.

Edgar A. Godoy-Garcia

Sanitation of stainless steel wine storage tanks is a critical component of quality control in commercial winemaking operations. Ineffective cleaning can lead to microbial contamination, product spoilage, and safety concerns. Traditionally, wineries rely on manual scrubbing, chemical cleaning agents, and extensive water rinsing cycles to maintain sanitary tank conditions. However, these methods are resource-intensive and may pose risks to both workers and the environment due to chemical exposure and wastewater generation. In response to growing industry interest …

Summaries Of Arkansas Cotton Research 2024, Fred M. Bourland

Arkansas Agricultural Experiment Station Research Series

Planted cotton acreage in Arkansas increased in 2024 to 670,000 planted acres, which was 160,000 acres more than in 2023 when Arkansas producers planted approximately 510,000 acres of cotton. A wet spring, and two hurricanes in three weeks in late summer/early fall led to a slight decrease in harvested acres that culminated in a final number of 640,000 (https://www.nass.usda.gov/Quick_Stats/Ag_Overview/stateOverview.php?state=ARKANSAS). Producers harvested 640,00 acres of cotton, which ranked third nationally, behind Texas and Georgia (https://downloads.usda.library.cornell.edu/usda-esmis/files/k3569432s/nk324887m/qn59s0097/cropan25.pdf). The total harvested acreage is the greatest amount since 680,000 acres in 2011. The average cotton yield in Arkansas in 2024 was …

Understanding Potential Profitability Estimates For Western Kentucky Grain Production, Austin Randolph, Naveen Musunuru

Honors College Theses

Profitability remains a persistent challenge for grain farmers across the United States and globally. Without profitability, the continued operation of any grain farm becomes unsustainable. For grain farmers, profitability is not merely a financial goal but a crucial determinant of their livelihood. However, many grain producers face a significant obstacle: a lack of reliable tools to predict profitability and plan for the next season or make adjustments to existing operations. While budgets can offer a framework and tentative guidelines for farmers to follow, fluctuations in market prices can ultimately undermine these financial plans. The objective of this project is to …

Fractured Inheritance: Quantifying The Economic Impact Of Heir’S Property On Arkansas Farmers, Makenzie Mcjunkins

Graduate Theses and Dissertations

Heir’s property arises when the original owner still holds the title despite their passing, and ownership is distributed among their heirs. This was driven by barriers to retaining land ownership and access to legal support in predominantly African American populations in the early 20th century. This approach allowed land to remain in the original owner's name while granting continued ownership to future generations without formal paperwork. Additionally, allowing limited land access, land management, and disparities in capital access compared to property with direct ownership rights. This analysis examines how modern heir’s property impacts agricultural returns. This study develops a conceptual …

Land is a key component of the agriculture industry in the United States. According to the United States Department of Agriculture, farm real estate (land and buildings) accounted for 82.8% of total US farm sector assets in 2022, consequently making land the largest source of wealth in a farmer’s investment portfolio and the primary source of collateral used for farm operating loans. The Southeastern region of the United States has seen rapid farmland appreciation and intense population growth in recent years. This research investigates the rising farmland prices across the Southeast from both a regional and state-level perspective. Chapter Two …

Berm-Leveling Machine For Peach Orchards: Incorporation Of Tree-Sensing Feature And Profitability Study, Shubham Singh

All Theses

Root collar excavation extends the productive life of peach trees in Armillaria root rot-infested soil, but the process requires trees to be planted on berms. Berm-planted peach orchards restrict the mobility of workers and machinery and can lead to increased erosion in furrows on either side of the berms. The current inter-tree berm-leveling machine depends on the driver's command to dodge the peach trees. The objectives of this thesis were to (1) integrate the feeler, infrared, and LiDAR-based tree sensing systems in the berm-leveling machine to make the soil excavating head's movement independent, (2) measure the impact of finger weeder-based …

Livestock Risk Protection Basis Risk For Feeder Cattle, Bryce Anderson

Graduate Theses and Dissertations

Recent government subsidies make livestock risk protection (LRP) insurance an affordable price risk management tool for many U.S. cattle producers. LRP insurance triggers a loss when the Chicago Mercantile Exchange (CME) Feeder Cattle Index falls below the selected coverage price. The CME Feeder Cattle Index is a 7-day weighted average of feeder cattle prices in 12 states. This paper determines if LRP policy holders who produce feeder cattle in states whose feeder cattle prices are not included in the CME Feeder Cattle Index are exposed to excess basis risk. To do this, we use a hedonic regression model to determine …

The results of this study are anticipated to be a starting point for more sophisticated and dynamic analysis of pricing and willingness-to-pay studies in the pet food industry.

Where Is Your Crop Insurance Agent? Understanding The Geographical Distribution Of Agents, Cory Walters, Nathan Delay

Cornhusker Economics

Following the modifications to the Standard Reinsurance Agreement (SRA) in 2010, there was limited understanding of the impact of policy changes on agent availability. Our objective is to construct a model of the equilibrium supply of crop insurance agents and to test hypotheses regarding the factors influencing agent concentration, such as commissions, competition, and risk. We developed a theoretical equilibrium model of the federal crop insurance market, which encompasses three tiers: insurance companies, agents, and farmers. The model incorporates key features of the federal program, including government-set premiums and the stipulation that agents cannot refuse coverage or modify premiums for …

Efficiency’S Role In Irrigation And Nitrogen Use, Matt Stockton, Shannon Sand

Cornhusker Economics

Summary

The WNIPI is a purely physical measure of I and N efficiency and was developed to determine efficiency winners in several TAPS contests. DRIN is a powerful tool in measuring the effectiveness of the dollars spent on I and N. It is a ratio of dollars returned as revenue in terms of dollars spent. The third measure, NRIN, is an overall measure of economic gain. It is the difference in money spent on I and N versus the revenue taken in and measures the volume of net returns. Both DRIN and the NRIN measure dollar effectiveness dependent on the …

Additionality Of Solar Tax Incentives Under Community Choice Aggregation In Ohio, Michael L. Smith, Carson Reeling, Michael D. Wilcox

Department of Agricultural Economics Faculty Publications

In the State of Ohio, the electric regulatory landscape permits local governments to become energy suppliers to residents and small businesses through community choice aggregation (CCA). Some CCAs provide enrollees 100% renewable electricity. Concurrently, the federal government offers an income tax credit (ITC) for the purchase of a solar array. With policy incentives, it is important to ensure they encourage behavior beyond the baseline scenario without the ITC. This is known as “additionality.” Renewable aggregation programs may crowd out the benefits of the ITC, violating additionality. This paper assesses additionality of the ITC in the context of Ohio’s CCA programs. …
