The National Center for Appropriate Technology

NCAT's sustainable agriculture service, ATTRA has been providing trusted, practical, and free information for farmers and ranchers since 1987. Over the last 34 years, the program has developed a vast knowledgebase meant to help beginning farmers get their start, to provide continuing education to longtime producers, and to connect farmers and ranchers with information, experts, and the know-how to run a successful, and safe, enterprise.
