Cooperative Extension System
Your local Cooperative Extension office provides research-based advice on agriculture and horticulture that is specific to your region. The US Cooperative Extension System offices are staffed by experts who can help answer your questions about pest and disease management, growing conditions, sustainable agriculture, farm management, and more. Local educational programs and publications are also offered.
The National Institute of Food and Agriculture (NIFA) of the USDA, administers funding for Cooperative Extension offices, in cooperation with state and county governments and land-grant universities.
The Cooperative Extension System additionally offers programs in a variety of other areas including Family, Youth & Communities; Food, Nutrition & Health; Economics & Community Development; Education; Animal Agriculture; and more.
Each US state and territory has a state office at its land-grant university and a network of local or regional offices. These offices are staffed by one or more experts who can help with research-based information.
eXtension.org is an interactive learning site offering research-based information from America's land-grant universities, including articles, videos, webinars, and additional resources.
