4-H does not have specific membership requirements. All youth from Kindergarten through Grade 13 are welcome to join. Whatever you love to do, you can find it here! Jefferson County offers enrollment in 25 clubs, countywide projects, and select school programs.

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.**

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
