Welcome to UD Cooperative Extension

We have expert answers. From nutrition , Master Naturalist , Master Gardeners to 4-H youth clubs and programs that support local agriculture — UD Cooperative Extension has something for everyone!

Why Exposing Youth to Agriculture Matters
April 21, 2026 | Written by Kaitlin Rogers, Extension Educator II - 4-H Youth DevelopmentDelaware may be the second smallest state in the nation, but its agricultural presence is certainly not to be underestimated. Chances are, no matter where you're headed, a farm is part of the scenery along the way, from fields on the way to the beach to hidden gems throughout Wilmington.
