Washington Tilth Association
The Washington Tilth Association is a 501(c)3 organization organized in 1977 as part the general "tilth movement" within the Pacific northwest. Serving as an umbrella organization for several autonomous chapters, WTA itself has a board made up of chapter representatives who meet annually but have no centralized staff. WTA functions as a "fiscal sponsor" for four of its chapters, but not all.
