An Exploration Of Learning And Teaching Methods In Agricultural Extension, Jeremy Levinson, Dave Lamie, Michael Vassalos, Chris Eck, Juang Chong, Francis P. F. Reay-Jones

The Journal of Extension

Abstract

The Train-the-Trainer approach is widely used in Cooperative Extension education to efficiently disseminate research-based information to many clientele groups, including farmers. This paper compares the traditional Train-the-Trainer model to a comprehensive Collaborative Train-the-Trainer model and discusses weaknesses of the traditional model that are addressed in the Collaborative model. Sources of information used by farmers (growers) and overall effectiveness were measured through a survey instrument created and distributed to farmers in South and North Carolina. The Collaborative Train-the-Trainer model, which emphasizes peer-to-peer interaction and feedback loops, represents an enhanced approach for conceptualizing and implementing Extension educational programs.

Hay Inventory And Purchasing Calculator For Horse Owners, Robyn L. Stewart, Brooklyne M. Wassel

The Journal of Extension

The Hay Inventory and Purchasing Calculator for Horse Owners is an Excel-based tool for estimating hay needs and expenses for horse owners. Challenges with hay quality and availability can result in higher than expected costs for horse owners as they attempt to purchase enough horse-quality hay to meet their needs. Estimating intake requirements and creating a budget for hay purchasing is key for the effective management and profitability of equine operations. This tool can be used regardless of geographic location and will benefit a diverse audience including Extension educators, equine business owners, and horse owners.

On-Farm Hog Processing Demonstration For Teenage Exhibitors: Blending Academic, Laboratory, And Farm-Based Learning, Katherine A. Wells, Chris L. Bruynis, Lyda G. Garcia

The Journal of Extension

COVID-19 challenges induced a U.S. meatpacking industry bottleneck. [University] Extension identified the need and responded by creating a three-step hands-on training for teenage junior fair exhibitors. [University] Extension Meat Scientist and graduate students assisted in demonstrating an on-farm hog harvest and processing event in collaboration with a local Extension office for 4-H and FFA teenagers. To add a practical perspective, a local hog-producing and harvesting family was asked to assist with the event. An online post-survey reflected 90-100% gains in five educational areas and 100% said they would a similar event in the future and recommend it to a friend.

Perceived Benefits And Barriers To Livestock Mortality Composting, Rachel Wieme, Lynne Carpenter-Boggs

The Journal of Extension

We conducted webinars in 2020 about livestock mortality composting (LMC). Forty-five attendees completed a survey to evaluate the webinar and help define future educational needs. Major barriers to LMC were lack of experience, public and neighbor perceptions, and environmental management. Most respondents indicated convenience, cost, biosafety, use of product, and environmental management as benefits. An unexpected emotional theme indicated that LMC also supports the “circle of life” and “respect for the animal.” We propose that this theme may be a uniting message to improve public and producer perception of LMC, increase use of LMC, and improve public-producer relationships overall.

An Evaluation Of A Cooperative Extension Internship Program, Lisa Ellis Mccormick, Karen A. Vines, Subrato Kumar Kuri

The Journal of Extension

The purpose of this project was to evaluate the Virginia Cooperative Extension internship program from the perspective of student participants and their supervisors. Three focus groups were conducted with internship supervisors from the summer of 2019. Student survey data was used to identify concerns from the student perspective to inform the supervisor focus group questions. In addition to the questions, a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis was also used to collect qualitative data within the supervisor focus groups. Findings suggest areas of strength that can be used in marketing as well as opportunities for program improvement.

Developing Economic Injury Levels For Thrips (Frankliniella Occidentalis) In Idaho Alfalfa Under Controlled Pest Populations, John Reed Findlay, Joseph Sagers

The Journal of Extension

Thrips are a new pest of alfalfa in Eastern Idaho. University of Idaho Extension Educators studied the yield losses associated with this pest in a controlled greenhouse experiment. This data has been used to calculate the economic injury level (EIL) of thrips in alfalfa. The EIL represents the level of insect infestation at which control measures will begin to be economically viable. We calculate that for the 2021 growing season conditions the EIL was approximately 20 thrips per six stems. We also calculated EIL curves that growers and consultants can use as spray costs and hay values change.

Consumer-Focused Meat Science Extension Program Increase Consumer Confidence And Knowledge Of Meat Selection And Preparation, Stacy Zuelly, Yufei Guo, Melinda Dennis, Emily Ford, Melissa Davis

The Journal of Extension

Science-based, meat science education is often limited outside of universities, creating possibilities to develop Extension activities to educate and impower consumers in principles of meat science. The Indiana BBQ Bootcamp was developed to provide consumers information on meat selection, proper cooking techniques, food safety, and meat seasoning (spice rubs and marinades) through demonstrations and product sampling. Attendees were surveyed before and after the program to report their confidence in their ability to perform basic meat science techniques. Responses to all survey questions showed significant increase in the attendees’ confidence demonstrating improvement in their meat science knowledge.

Using Multimedia To Help Agricultural Producers Communicate With Consumers About Gmos, Stacey F. Stearns, Jennifer E. Cushman, Joseph A. Bonelli, Bonnie E. Burr

The Journal of Extension

Genetically modified organisms (GMOs) and their uses are often misunderstood. Consumers are regularly unsure what GMOs are, or if they are safe for consumption and the environment. Contradictory and sometimes inaccurate information is available from numerous sources, and challenges consumers and others to separate the facts from sensationalized stories. Agricultural producers often communicate with consumers, neighbors, and members of the general public; however, they do not have information to share about GMOs. Multimedia resources can provide agricultural producers with science-based information to share with consumers. Agricultural communicators and Extension educators can create science-based multimedia resources to bridge the communication gap.

Offering Collegiate Livestock Judging As A Student Organization, Maryfrances Miller, Don W. Edgar, Lyle Logemann

The Journal of Extension

Resource constraints have lowered the number of collegiate livestock judging teams, dropping the number of opportunities for collegiate judging, even though interest among students remains high. These opportunities can be provided for less expense through student-led extracurricular organizations. This approach increases the student initiative required, but also provides an increased opportunity for developing and demonstrating leadership skills.

The Journal of Extension

The number of small-scale and backyard operations has increased in the United States during the past decade, but there is currently a lack of outreach efforts and readily-available educational materials targeting these farming systems. We developed a webinar series on biosecurity to provide training for small-scale and backyard producers, and training tools that can be used by local veterinarians and extension educators to disseminate knowledge and consistent recommendations more effectively. Fewer people attended the webinars than registered, suggesting a gap between interest in biosecurity and commitment to the topic. Participants in the webinar series reported a high level of satisfaction …

Revisiting The Master Food Volunteer Program: Examining How To Enhance Nutrition Education In The United States, Stacey Viera, Lindsey Haynes-Maslow

The Journal of Extension

America’s diet-related illness crisis intersects with a lack of nutrition literacy, nutrition security, and systemic inequities. The Cooperative Extension Service’s (CES) national infrastructure could potentially provide equitable access to quality nutrition education in the US utilizing a Master Food Volunteer (MFV) model. This research brief examined preliminary evidence for the MFV model as a support for CES agents and paraprofessionals, and results show a paucity of evidence. Further research and a pilot program with pre-established measures for health-related knowledge and behaviors could elucidate the model’s potential to increase equitable access to evidence-based programming, nutrition, and implementation guidance.

Texas A&M Beef Cattle Short Course: Program Evaluation, Nicola Oosthuizen, Pedro Fontes, Graham C. Lamb, Jason J. Cleere

The Journal of Extension

Survey results (n = 3,748) collected over a period of 7 years from the Texas A&M Beef Cattle Short Course (BCSC) were analyzed to evaluate course demographics and the impact of the course on attendees. Results of this survey demonstrate that attendee demographics of the BCSC are representative of beef cattle producers in the United States and that the BCSC is effective at delivering information that positively impacts beef production in Texas. Extension professionals can make use of these findings to tailor future education programs to better serve the needs of beef cattle producers nation-wide.

Effect Of Authentic Kefir And Nigella Sativa On Broilers Challenged By Coccidia And Clostridium Perfringens, Julian E. Nixon

All Dissertations

Black seed oil concentrations of 0%, 0.1%, 1% and 5% were added to milk inoculated with kefir grains and incubated at 25°C for 22 h. The pH and microbial count indicated 1% black seed oil caused low inhibition (P > 0.05) of fermentation, but 5% black seed oil caused significant inhibition of the kefir microorganisms (P < 0.05).

Cobb 500 male chicks (n = 256) were distributed in a randomized block design and received one of four treatments: CTRL1 (Non-medicated, no kefir, no Clostridium perfringens), CTRL2 (Non-medicated, no kefir, C. perfringens inoculated), CTRL3 (BMD medicated, no kefir, C. perfringens inoculated), KTRT (Non-medicated, …

Virtually The Same? Understanding Virtual And F2f Farmer Audiences, Laura Witzling, Eric Williams, Dara M. Wald, Jacqueline Comito, Elizabeth Ripley

The Journal of Extension

Agricultural and extension educators frequently employ a variety of methods to provide farmers with information about conservation practices. The introduction of virtual programming brought on in response to the COVID-19 pandemic set the stage for analysis of farmer outreach preferences with respect to face-to-face (F2F) versus virtual outreach. Using survey data of individuals who participated in field days in Iowa, we segmented participants based on their F2F or virtual attendance. We compared the groups based on key variables such as water quality concerns, communication behaviors, outreach preferences, and demographics. Our work suggests that a broad and dynamic communication strategy, including …

Shiny Apps: The Evolution Of Extension Tools From Spreadsheets To New Interactive Dashboards, Allan Fabricio Pinto Padilla, Terry Wayne Griffin

The Interactive web dashboard is the newness with characteristics and features that are replacing the status quo downloading spreadsheets. RStudio is the program used to create Shiny Apps dashboards with R. We explain some of those features so that Extension specialists can adopt the methodology, engage stakeholders, and help them understand and apply results to their production systems, although we do not explain the creation process step by step. Our approach offers not only a useful and modern way to disseminate information to empower decision-making, but also a safe environment in which data can be automatically updated and users cannot …

Pursuing Antiracist Public Policy Education: An Example Connecting The Racist History Of Housing Policy To Contemporary Inequity, Craig W. Carpenter, Tyler Augst, Harmony Fierke-Gmazel, Bradley Neumann, Richard Wooten

The Journal of Extension

We review the antiracism concept and contextualize it in Extension public policy education and the Extension system itself. Despite public policy education having a long history in Extension on a wide variety of issues, missing from this programming is the pursuit of antiracism. As a programmatic example, we review some historical causes of present-day housing inequities and an associated example approach for pursuing antiracism in housing policy education. Finally, we conclude by noting additional opportunities to pursue antiracism in Extension public policy education. In doing so, we emphasize that public policy education cannot be “nonracist” if it is not antiracist.

The purpose of this study is to measure any increase in agricultural awareness and literacy of South Carolina 8^th-grade social studies teachers participating in a five-day study tour (SOCIAL tour) through mixed method procedures. A pre and post-tour survey given to participants indicated a significant increase in knowledge and perception of agriculture …

Comparing The Economic Efficiency Of Payment Structures To Subsidize On-Farm Greenhouse Gas Abatement In Iowa, David Mansfield

All Theses

Abating greenhouse gas (GHG) emissions in the agricultural sector can help
combat climate change and meet the goals of the 2015 Paris Climate Agree-
ment. The agricultural sector can sequester soil organic carbon and, by adopt-
ing conservation-driven land-use decisions, such as reducing or stopping tillage,
increase carbon storage in soil and reduce nitrous oxide (N2O) emissions.
This thesis will compare the cost of achieving different levels of GHG emis-
sions reduction through payments based on: 1) region averages for GHG emis-
sions by crop and practice, without considering additionality, 2) region averages
for GHG emissions by crop and practice …

Biosensor is a promising user-friendly detection tool that could transduce biological or chemical interactions into electric signals. Among various types of biosensors, aptasensor, which use aptamers as recognition elements show potential as a high throughput, in-field test. The goal of this thesis is to develop an electrochemical aptasensor testing system for ASPV detection. The quality control study of laser inscribed graphene (LIG) based working electrode of the biosensor was conducted …

Understanding Current Labor Shortage And Mechanization In New Jersey Nursery Crop Operations, Hemant Gohil, Timothy Waller, Raul Cabrera

The Journal of Extension

We conducted a survey of New Jersey’s nursery industry to understand the current levels of labor shortage, how this has affected specific tasks related to the production capacity of the industry, and the actual level of mechanization. Survey results identified priority areas needing mechanization. There is a need for greater mechanization in almost all areas of nursery production to reduce the reliance on labor and or improve the efficiency of labor. Other Implications related to Extension programming on nursery mechanization are also discussed.

Connecting Diverse Communities Through A 4-H Urban-Rural Experience, Laurie Murrah-Hanson, Brittani Lee, Pamela Bloch

The Journal of Extension

Misconceptions regarding agricultural careers are exacerbated by increasing urbanization and are one of many differences in perspective between urban and rural communities. The One Georgia 4-H Urban-Rural Experience addresses this divide through a statewide youth exchange focusing on the agricultural sector. The program includes a multifaceted look at agricultural careers through visits to urban and rural communities. Focus group evaluations revealed the impact on youth through exposure to new careers, increased understanding of the diversity of agriculture, awareness of the interconnected nature of urban and rural communities, and a sense of belonging to a diverse group of youth.

Estimated Impact Of X-Disease And Little Cherry Disease In Washington And Oregon From 2015 To 2020, Cody Molnar, Tianna Dupont, Ashley Thompson

The Journal of Extension

X-disease phytoplasma and little cherry virus 1 and 2 have resulted in substantial loss of stone fruit acreage in Washington and Oregon. The extent and financial impact on the industry was not previously known. A Washington and Oregon State University survey documented 238,856 trees equivalent to 974 acres of sweet cherries removed due to X-disease and little cherry disease between 2015 and 2020. Removed trees reduced revenue to the industry by an estimated $30 million in 2020 and $65 million between 2015 and 2020. Over the seven-year re-establishment period estimated lost revenue and establishment costs to growers is an estimated …

Is There An Economic Advantage To Planting Diverse Summer Annual Forage Mixtures?, Kelly Mercier, Chris Teutsch, Ray Smith, Kenny Burdine, Edwin Ritchey, Eric Vanzant

The Journal of Extension

This study examined economic implications of planting summer annual mixtures of grasses, legumes, and forbs at varying nitrogen rates. No differences in yield occurred between the three mixtures, indicating that mixtures with lowest seed cost will be most economical. Applying N resulted in yield increases of 12.26 lb DM per lb N applied. Although yield responses to N were positive, sensitivity analyses showed that applying N resulted in positive net returns only when hay prices were high and N prices were low. When utilization rates are accounted for, enterprise budgets determined grazing to be 18% cheaper to implement than haying.

An Economic Impact And Investment Analysis Of Armillaria Root Rot In The United States Peach Industry, Gracie Herrin

All Theses

Peach production in the United States has decreased over the last decade due to increased disease prevalence. Armillaria root rot (ARR) is a lethal root fungus that affects many stone fruits, including peaches, often leading to rapid decline/death of trees and abandonment of orchards. This thesis is divided into four chapters which focus on answering four key questions that, to the best of my knowledge, have not been addressed in previous industry research.

The second chapter determines the magnitude of ARR disease prevalence in the United States and producers’ maximum willingness to pay (WTP) for a theoretical ARR-resistant rootstock. Results …

Engaging Farmers, Culinary Schools, And Communities In Value-Added Production To Strengthen Local Food Systems, Lauren B. Errickson, Ethan D. Schoolman, Virginia Quick, Sarah Davis, Anthony Capece

The Journal of Extension

Value-added products can generate farm income and improve community food access, yet lack of available kitchen infrastructure and labor can limit farm production capacity. This project explored how community-based culinary schools might fill the gap. A unique “product share” model was identified and piloted, meeting the collective needs of farmers, a culinary school, and urban consumers. By researching farmer crop availability and business model preferences, and aligning value-added production with community food preferences, we demonstrate a successful pilot indicative that similar initiatives can be replicated in other metropolitan areas, with potential to engage cross-disciplinary extension professionals.

Weather Information And Decision-Support Tool Needs Assessment, Lily Calderwood, Glen Koehler, Sean Birkel, Erin H. Roche

The Journal of Extension

University of Maine researchers developed three commodity-specific grower focus groups (lowbush blueberry, apple, mixed vegetable) to discuss and survey 1) current access to weather information, and 2) interest in weather-based decision support tools. NOAA National Weather Service (30%) (n=47) was most commonly cited as a weather information source. Growers ranked greater forecast accuracy (31%) and localization (19%) (n=48) as highest priorities. Only 34% of growers reported current use of weather-based decision support tools, but 86% expressed interest in future use (n=134). The project team is using grower input to improve weather data access and decision-support tools for Maine farmers.
