How Wisconsin Extension Educators Talk About Climate Change Without Talking About ``Climate Change'', Sky Hershberger, Todd P. Newman

Journal of Extension

Climate change touches all areas of Extension's programming. To understand how educators approach talking about climate change with constituents, we interviewed 15 Extension educators and three program managers in Wisconsin. Crops and Soils educators view climate change as interwoven with their work, Financial Education educators view it as mostly disconnected, and Community Economic Development educators range between these extremes. Educators in all three programs avoid the polarizing phrase ``climate change,'' instead focusing on specific, local, and relatable issues. Educators show empathy and emphasize resilience (adaptation) rather than mitigation. These findings can inform Extension's organizational strategy on climate change.

Are Extension Agriculture Programs Hitting Their Target With Military Veterans?, Adam Ingrao, Craig W Carpenter, Michael Lotspeich-Yadao, Charles M. Tolbert

Journal of Extension

The desire to support military veterans has led to a variety of targeted Extension programs, but the types and availability of these programs vary substantially. After reviewing the size and diversity of the U.S. veteran population, we examine one of the main USDA programs targeting veterans: the Beginning Farmer and Rancher Development program. We then use matrix analysis to categorize veteran support programs across other program areas. Finally, we compare these programs with veterans' needs, as described in recently conducted veteran focus groups, and conclude by highlighting gaps and opportunities for improving Extension programming for veterans, including substantially improving program …

Effects Of Irrigation And Nitrogen Management On Yield And Leaching Risk In Organic And Conventional Broccoli Fields, Shane Egerstrom

Master's Theses

Under regulatory pressures to reduce groundwater contamination by nitrate from fertilizer, such as those posed by the Central Coast Regional Water Quality Control Board’s Agricultural Order 4.0, a need exists to better understand interactions between irrigation and nitrogen (N) management. To increase N use efficiency (NUE), growers are encouraged to account for additional sources of N in their management plans, such as irrigation water N and preplant soil N. The availability of these N sources for plant uptake and how it is affected by other management conditions is not yet well documented. We conducted 6 field trials, 3 organic and …

Evaluation Of Fertilizer Recommendation And Soil Amendment Impacts On Crop Production In The Intermountain West, Megan Baker

All Graduate Theses and Dissertations, Fall 2023 to Present

Fertilizers improve crop yield and quality by supplying crops with essential nutrients, but can also be a significant input cost. Determining what nutrients and rates to apply for optimal crop growth can be difficult, leading many growers to use external sources for these decisions. Land-grant universities are a common source for fertilizer recommendations, but often based on decades-old research and should be evaluated periodically to verify effectiveness and calibrated to current soil analysis methods. Current Utah State University (USU) guidelines for sulfur (S) and zinc (Zn) were tested across Utah in on-farm trials in 2021-2025. Zinc applications of 5 or …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …

Predicting, Culturing, And Characterizing Beneficial And Detrimental Strains Associated With Plant Phenotypes., Anastasiia Onyshchenko

Arts & Sciences Graduate Student Theses and Dissertations

Modern agriculture’s reliance on chemical fertilizers has greatly increased crop yields but has also contributed to soil degradation, environmental pollution, and unsustainable resource use. Plant growth–promoting rhizobacteria offer a sustainable alternative, enhancing plant growth through mechanisms such as nitrogen fixation, phosphate solubilization, siderophore production, and phytohormone modulation, while also protecting plants against pathogens and abiotic stresses. However, soil microbial communities are highly diverse and structurally complex, making the isolation of individual beneficial strains challenging. Traditional approaches rely on selective media and labor-intensive phenotypic screening, which often capture only a small fraction of soil diversity. To overcome these limitations, we combined …

Gene Editing Approaches To Improving Grain Amino Acid Profiles In Maize And Sorghum, Joseph Preston Hurst

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Maize grain is deficient in lysine. While the opaque2 mutation increases grain lysine, o2 is a transcription factor that regulates a wide network of genes beyond zeins, which leads to pleiotropic and often negative effects. Additionally, the drastic reduction in 19kDa and 22kDa alpha-zeins causes a floury kernel, unsuitable for agricultural use. Sorghum, closely related to maize, has a similar lack of lysine that can be corrected with prolamin alteration and also subject to the same deleterious kernel texture. CRISPR/cas9 gives researchers the ability to directly target genes of interest. In this research, gene editing was used to specifically target …
