From Steiner's group the world's first organic certification was born in the late 1920's. That was a full 20 years before certification came to the surface in England and almost 50 years before the first organic certification process in the USA was born in Ellensberg, Washington when the group Regional Tilth was established and out of that came Oregon Tilth, California Certified Organic Farmers (CCOF), Washington Tilth, et al.
Biodynamic certification is still the most difficult to earn closely followed by Oregon Tilth and then CCOF.
