Become a Volunteer

Youth involved in 4-H are 4x more likely to give back to their communities, 2x more likely to make healthier choices, and 2x more likely to participate in STEM activities! Through a variety of programs, 4-H’s unique hands-on approach gives kids the opportunity to learn by doing and build life skills.*
By working together in youth-adult partnerships, those who participate in 4-H become more connected and responsive to the needs of the community and gain new energy, perspective, and ideas.**

Agriculture
Manage Nitrogen Efficiently

In April 2026, commercial nitrogen (N) fertilizer prices increased approximately 30% since fall 2025. Fortunately, there are nutrient management choices farmers can make to minimize financial impacts of this sudden price increase.
- Identify a Cost-Effective N Rate
- Account for On-Farm Nitrogen Sources
- Assess Soil N Credits
- Measure Field Nitrogen Use Efficiency
Calf Care & Development

The training of the farm personnel has positive impacts on animal welfare and performance, thus increasing the overall farm profitability. To support beef and dairy farms and their employees, the University of Wisconsin-Madison, Extension Dairy Program has developed the “Calving Management Practices and Neonate Care in Dairy Cattle” workshop.
Badger Dairy Camp

The Department of Animal and Dairy Sciences and the Dairy Innovation Hub are excited to announce the return of Badger Dairy Camp to the University of Wisconsin campus from July 9-12, 2026.
