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.

Development Of Water-Soluble Nanofibrous Poly(Vinyl Alcohol) Collectors For Bioaerosol Sampling And Environmental Surface Microbial Detection, Kevin Crown

Theses & Dissertations

Environmental surveillance for pathogenic microorganisms requires sampling technologies capable of efficiently collecting biological particles from air and surfaces for downstream detection.  Current environmental sampling materials, such as fibrous aerosol filters and surface sampling swabs, are designed to capture particles effectively but often retain a portion of the collected material during extraction.  Incomplete recovery reduces the sensitivity of microbiological and molecular detection, particularly in situations where microbiological concentrations are low, such as in environmental monitoring and clearance sampling following biological contamination events.  This dissertation describes the development and evaluation of water-soluble nanofibrous sampling materials designed to improve microbial recovery while maintaining …

Expanding Regenerative Agriculture Practices In East Texas, Treasure Hance

Electronic Theses and Dissertations

Regenerative agriculture has increasingly been referenced since 2015 for its ability to provide healthy food with less environmental and social impacts. Its basic premise/ideology is to follow a process whereby soil, biotic, and human communities are not just maintained but prepared to return to a better state. Soil health is a primary concern. Actions include no-till planting, composting to create more organic soil, less use of synthetic fertilizers and pesticides, along with better employment, animal care, and ecological outcomes/practices. Regenerative versions of other professions, such as regenerative medicine (e.g. gene/stem cell therapy) and regenerative architecture (design for surplus energy, restored …

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 …

Are Sticky Prices Present In Us Ag Land Lease Rates, John Tyler Blazzard

Graduate Theses and Dissertations

Land is an essential resource in production agriculture. Limited supply and high demand for land have resulted in increasing land values which are a barrier to entry for beginning farmers and ranchers with limited access to capital and credit. One way to overcome the high costs of purchasing land is to lease it. While more affordable than purchasing land, cash rents are also increasing. The objective of this research is to determine whether agricultural cash rents follow farm income symmetrically over time. This is accomplished by implementing Ordinary Least Squares (OLS) regressions with two-way fixed effects which account for rental …

Evaluating Short-Day And Intermediate-Day Sweet Onions As Early-Season High Tunnel Onions In West Virginia, Lewis Jett
