Understanding Agricultural Irrigation Practices Along Utah's Wasatch Front Through Farmer-Reported Data, Garland Ledbetter

All Graduate Theses and Dissertations, Fall 2023 to Present

Water is a growing concern in Utah, especially along the Wasatch Front, where cities, farms, and communities all rely on the same limited water supply. Agriculture uses a large portion of the state’s water, so understanding how farms manage irrigation is important for statewide water planning. Utah currently uses a dataset called Water-Related Land Use (WRLU) to estimate agricultural water use across the state. This dataset provides useful information about irrigated land and crop types. However, it does not capture many of the day-to-day decisions farmers make when managing irrigation.

To better understand irrigation practices, this study surveyed 61 farmers …

Flexible Grazing: Evaluating Stocker Cattle As A Drought Management Tool For Utah Livestock Producers?, Ross Israelsen

All Graduate Reports and Creative Projects, Fall 2023 to Present

Drought is a persistent concern in the western United States, often leading to reduced forage production, overgrazing, and economic challenges for livestock producers. This study evaluates the economic feasibility of incorporating stocker cattle as a flexible drought management strategy under varying forage conditions across four Utah grazing locations: Park Valley, Nephi, Vernal, and Beaver. The Rangeland Analysis Platform (RAP) was used to estimate annual forage production and stocking rates from 2001 through 2025. Four stocking-rate scenarios (100%, 75%, 60%, and 50% cow–calf stocking rates) were evaluated using a Net Present Value (NPV) framework to compare the economic performance of traditional …

Estimated management costs and losses due to insects and other invertebrates in soybeans during the 2025 growing season were collected and compiled from 20 states to provide a record of insect pressure and management practices for the year. These annual estimates provide a historical record of pest pressure and insect management and have been compiled in some states since 2004. Participating states accounted for 68% of soybean acreage in the United States, with near 100% participation in the southern states. As has been true in previous years, the stink bug complex was the costliest insect pest in soybean followed by …

Estimating A Model Of Forward-Looking Behavior With Discrete Choice Experiments: The Case Of Lifetime Hunting License Demand, Matthew Gibson, Marina Sundiang, Daniel Mason-D’Croz, Thais Diniz Oliveira, Felicitas Beier, Lauren Benavidez-Brouk, Astrid Bos, Maksym Chepeliev, Jonathan Doelman, Shahnila Dunston, Shinichiro Fujimori, Tomoko Hasegawa, Petr Havlik, Jordan Hristov, Jonas Jägermeyr, Marta Kozicka, Marijke Kuiper, Page Kyle, Thijs De Lange, Benjamin Leon Bodirsky, Hermann Lotze-Campen, Hermen Luchtenbelt, David Meng-Chuen Chen, Abhijeet Mishra, Christoph Müller, Gerald Nelson, Amanda Palazzo, Ignacio Perez Dominguez, Alexander Popp, Ronald Sands, Marco Springman, Elke Stehfest, Timothy B.

Food systems are a major contributor to exceeding planetary boundaries1,2,3 and poor quality diets are a key mortality risk globally4. Projected population and income growth could exacerbate these challenges5. In response, there are calls for transformation towards healthy and sustainable food systems6,7,8. However, the scale and distribution of the impacts of this transformation on agriculture are underexplored. Here we show that, by 2050, the transformation of food systems towards healthy diets (adoption of the EAT–Lancet reference diet), improved productivity and halving of food waste results in a fundamental restructuring of global agriculture, aspects of which break with historical trends. Scenario …

Recent Advances In Sustainable Production Of Enriched Chicken Eggs: A Mini Review, Karim El-Sabrout, Ayman Abd El-Aziz

Jurnal Ilmu Ternak Universitas Padjadjaran

Enriched or “designer” chicken eggs have emerged as an important category of functional foods aimed at improving human nutrition through dietary manipulation of laying hens. This mini-review summarizes recent advances in egg enrichment strategies, focusing on omega-3 fatty acids, vitamins, minerals, and antioxidant compounds. Omega-3 enrichment remains the most widely adopted approach, achieved through supplementation with flaxseed, fish oil, or microalgae, resulting in significant increases in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in egg yolk. Multi-nutrient enrichment, including selenium, vitamin E, and carotenoids, has also gained attention due to its potential in enhancing antioxidant capacity and health of hens …

Jurnal Ilmu Ternak Universitas Padjadjaran

This study aimed to determine the effect of adding parts of gowok fruit (Syzygium polycephalum) on the physical properties of goat’s milk yogurt. A completely randomized design was applied with treatments consisting of fruit parts (rind, flesh of fruit, and whole seedless fruit) and addition levels (1, 2, and 3%) with three replications. Data were analyzed using analysis of variance followed by Duncan’s multiple range test (DMRT). The results showed that gowok addition had a significant effect (P<0.05) on viscosity, syneresis, and color parameters, but no significant effect (P>0.05) on firmness and work of penetration. Yogurt viscosity ranged from 349.33 to 825 mPa·s and decreased with increasing gowok levels, while …

Financial Analysis Tool (Ct-Ft) For Western North Carolina Christmas Tree Growers, Sam Blumenfeld, Solomon Ghezehei, Justin G.A. Whitehill, Elizabeth G. Nichols

Journal of Extension

Western North Carolina is a major national Christmas tree (CT) production region, yet the CT industry faces numerous challenges that threaten its financial sustainability. Little economic research has been done, and limited decision-making tools exist to assist producers, Extension agents, and associated industry stakeholders. We developed an Excel-based financial analysis tool (CT-FT) to assist small and midsize wholesale CT producers in operational planning and financial assessment. The publicly available financial tools will enable CT growers to better understand their finances and operations, interact with financial stakeholders, assess alternative management scenarios, and track yearly costs to improve operational financial sustainability.

Nebraska And The Midwest Agtech Ecosystem: Benchmarking Innovation Investment And Translation Gaps, Ankit Chandra, Ishani Lal, Brennan Costello

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural innovation is central to the sustainable transformation of food systems, yet the capital that finances it is unevenly distributed relative to where food is produced. This paper develops a diagnostic framework for measuring this mismatch and applies it across the U.S. Midwest from 2021 to 2025, with particular emphasis on Nebraska's structural position within this landscape. Drawing on venture capital deal-flow data, 17 stakeholder interviews, and a novel strength-weakness-opportunity-gap (SWOG) ecosystem mapping methodology, we document $736 million in tracked Midwest AgTech funding across eight states (Nebraska, Iowa, Missouri, Illinois, Indiana, Kansas, North Dakota, and South Dakota). We introduce three …

Can Generative Ai Make Farming Decisions? Current Status And Future Pathways: A Case Study In Row Crop Production With Chatgpt, Nipuna Chamara, Yufeng Ge, Joe Luck, Yu Pan, Saleh Taghvaeian, Cory Walters, Christopher Proctor, Daran Rudnick, Daren Redfearn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The agricultural decision-making process is experience-based, knowledge-dependent, time-sensitive, complex, and driven by historical data. Planting, fertilization, irrigation, and chemigation are key categories in farm decision-making, and currently there is no one-shot decision-support tool that covers all these activities. Generative Artificial Intelligence (AI) models are more advanced than traditional machine learning and deep learning models. These models have been trained on vast amounts of data from the internet, allowing them to accept unstructured data in various forms and generate human-like text, solutions to problems, and scenario predictions. Given this capability, we became interested in exploring the potential of generative AI in …

A Hedonic Analysis Of Farm Tractor Auction Prices, Madison Pearson, Chad Fiechter, Andy Campbell

Department of Agricultural Economics Faculty Publications

Used farm machinery values play a critical role in farm management and in assessing the financial health of the agricultural sector. However, the heterogeneity of machines, particularly regarding embedded technology and usage, complicates efforts to isolate the factors that influence prices. This study leverages a detailed dataset from Tractor Zoom to estimate the effects of machine characteristics and market conditions on auction prices of used 300 to 450 horsepower tractors. We find a nonlinear relationship between machine usage and price: tractors with fewer than 500 hours of use lose approximately 118⁢𝑝⁢𝑒⁢𝑟⁢𝑎⁢𝑑⁢𝑑⁢𝑖⁢𝑡⁢𝑖⁢𝑜⁢𝑛⁢𝑎⁢𝑙⁢ℎ⁡𝑜⁢𝑢⁢𝑟,𝑤⁢ℎ⁡𝑖⁢𝑙⁢𝑒⁢𝑡⁢𝑟⁢𝑎⁢𝑐⁢𝑡⁢𝑜⁢𝑟⁢𝑠⁢𝑤⁢𝑖⁢𝑡⁢ℎ⁡𝑚⁢𝑜⁢𝑟⁢𝑒⁢𝑡⁢ℎ⁡𝑎⁢𝑛⁢10,000⁢ℎ⁡𝑜⁢𝑢⁢𝑟⁢𝑠⁢𝑠⁢ℎ⁡𝑜⁢𝑤⁢𝑜⁢𝑛⁢𝑙⁢𝑦⁢𝑎⁢𝑤⁢𝑒⁢𝑎⁢𝑘⁢𝑙⁢𝑦⁢𝑠⁢𝑖⁢𝑔⁡𝑛⁢𝑖⁢𝑓⁡𝑖⁢𝑐⁢𝑎⁢𝑛⁢𝑡⁢𝑑⁢𝑒⁢𝑐⁢𝑙⁢𝑖⁢𝑛⁢𝑒⁢𝑜⁢𝑓⁡𝑎⁢𝑏⁢𝑜⁢𝑢⁢𝑡2 per hour.

A Doubly Stochastic Model Of Government Interventions To Preserve Ecosystems Services In The Context Of Large-Scale Industrial Agriculture, Karma Brame, Wendy Calderon, Kaylee Clark, Josh Hiller, Natalia Negrete

Spora: A Journal of Biomathematics

Deforestation, driven by industrial agriculture and cattle farming, has significantly impacted communities and ecosystems across the globe. In this paper, we develop a discrete-time Markov model to evaluate the effectiveness of market-based interventions, such as payments for ecosystem services (PES) and taxes, in addressing forest loss within the context of large-scale agriculture. Specifically, we focus on how commodity price variability influences deforestation decisions. To model these price fluctuations, we represent agricultural prices as geometric Brownian motion (GBM). By linking commodity price dynamics to land use transitions, our model aims to provide insight into how financial mechanisms can slow or stop …

The Effect Of Climate Change On California’S Agricultural Economy, Anmol Singh

Honors Capstones

This study examines the relationship between climate variability and agricultural production in California, focusing on major specialty crops including almonds, walnuts, pistachios, and grapes. Using annual data from 1993 to 2023, the analysis evaluates how temperature and precipitation influence agricultural output while controlling for differences across crop types. The study employs ordinary least squares regression models using the natural logarithm of crop production as the dependent variable. In addition to a baseline linear specification, an extended nonlinear model including squared temperature and precipitation terms is estimated to test for potential nonlinear climate effects.

The results indicate that temperature has a …

The Effects Of Avian Influenza On Consumer Egg Prices In The United States, Jacob B. Franklin

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Outbreaks of highly pathogenic avian influenza (HPAI) create major challenges to poultry supply chains due to the high mortality rates in flocks, leading to disruptions in production and higher costs for producers. Using quantitative data from Federal Reserve Bank of St. Louis, USDA, and National Agricultural Statistics Service, this research analyzes changes in egg production, retail prices, and regional variations throughout the United States for the 2022-2025 HPAI event. A time-series regression model was used to control for production costs, seasonal patterns, and regional differences. All of these measures come together to quantify the impact of HPAI outbreaks on consumer …
