Welcome to UD Cooperative Extension
In 1869, the University of Delaware (UD) College of Agriculture and Natural Resources was established as the state’s land-grant university with a mission consisting of three elements: teaching, research and “extension”.
Cooperative Extension fulfills the third part of this mission: bringing knowledge to the people of Delaware. Today, we offer university knowledge, research and resources — just for you! You have questions.
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!
Make a Difference
Getting involved with UD Cooperative Extension is an excellent way to support and improve your Delaware community. Whether you're volunteering as a 4-H Adult Leader or donating to supporting an Extension Scholar, your local Master Gardener program, UD Cooperative Extension is grateful to have your involvement!
