The Biodynamic Association

Nurturing the biodynamic movement in North America through education, research, and development 

The Biodynamic Association (BDA) is an association of individuals and organizations in North America who are committed to the transformation of the whole food system, from farm to table, and who draw inspiration from the spiritual-scientific insights of Rudolf Steiner. Biodynamics is a worldwide movement for the renewal of agriculture based on an understanding of the spiritual forces at work in nature and in human social life. From this understanding, a particular form of organic farming has been developed that continues to grow and evolve around the world.


The Biodynamic Association (formerly Biodynamic Farming and Gardening Association) was formed in the U.S. in 1938. It is a non-profit, membership organization and is open to the public. The purpose of the Association is to foster knowledge of the practices and principles of the biodynamic method of agriculture, horticulture, and forestry in the North American continent and to advance the applications of this method through educational activities such as research, lectures, conferences; publishing and distributing literature on the biodynamic methods; and supporting consultation and extension services to farmers, gardeners, and foresters. It may undertake other charitable activities related to such principal purpose. The Association organizes conferences, workshops, and seminars and publishes books and a quarterly membership journal, Biodynamics. The Association supports regional, grass-roots membership associations and funds more formal research and training institutions.
