Jacob Hadfield serves as an Extension Associate Professor in Agriculture and Natural Resources at Utah State University, concurrently holding the position of Juab County Director. Based in Utah and Juab Counties, he actively engages with agricultural communities through USU Extension programs spanning Crops, Livestock & Dairy, Ag Economics, and Youth & Urban Outreach since 2019.
His academic credentials include a Master of Science in Animal Nutrition (2019) and Bachelor of Science in Animal Science (Production) (2017), both from Utah State University. His thesis investigated organic pasture effects on dairy heifer development. Professional certifications include Program Planning and Evaluation (2020) and Mental Health First Aid USA (2020).
Dr. Hadfield's research centers on sustainable agricultural systems, with primary focus on dairy heifer nutrition in organic pasture environments and cover crop management for corn production. His work examines birdsfoot trefoil integration in pastures, Parrot Feather aquatic weed control, and youth agricultural education. Extension efforts translate these research outcomes into practical field applications for Utah producers through fact sheets and workshops.
Analysis of his 2021-2024 publications reveals consistent interdisciplinary work bridging animal science and crop production. Key trends include optimizing pasture composition for dairy heifer performance, determining effective cover crop planting windows, and developing integrated pest management strategies for invasive species. His research demonstrates strong regional relevance to Utah's agricultural challenges while maintaining scientific rigor through peer-reviewed journal publications.
No scientific awards or graduate student advising details were documented in available materials. His extension role emphasizes community engagement over traditional academic advising, with no mention of externally funded research grants.
As Juab County Director, Dr. Hadfield leads collaborative efforts across USU Extension's program areas, working directly with agricultural stakeholders, county officials, and community organizations to implement research-based solutions for local farming operations and youth development initiatives.
