Who we are

The Biodynamic Association (BDA) is a charitable organisation founded in 1929 to foster and promote biodynamic farming and gardening in the UK. We give support and advice, publish our journal Star & Furrow, and organize regular workshops and conferences. We belong to the worldwide biodynamic movement, inspired by Rudolf Steiner’s Agriculture Lectures, given in 1924. Put simply, our aim is greater vitality for people and planet through more biodynamic acres, more biodynamic food, and more understanding of biodynamics.

Membership is open to everyone interested in biodynamics, whether or not they are practicing farmers or gardeners. The present subscription rate is £35 per annum for up to 2 members of the same household in the United Kingdom; £20 per annum for students, unwaged, and senior citizens; £40 for members in Europe; and £45 for all other countries.

We invite you to join our work by becoming a member.

Our contact details can be found here.

Our Roots in Anthroposophy

Biodynamics was first envisioned by Rudolf Steiner (1861-1925) in a series of lectures given in 1924. Since then biodynamics has spread and continued to develop worldwide. The Association keeps abreast of its developments in science, nutrition, education, health and social reform. It is linked to the Agricultural Section of the School of Spiritual Science (Switzerland) and affiliated as a group of the Anthroposophical Society in Great Britain. It is also a full member of Demeter International.

Biodynamics worldwide

Biodynamics is an international movement, practiced widely in over 50 countries. Currently there are approx 5000 certified biodynamic farms worldwide, though the number of farms, smallholdings, vineyards, gardens and private gardeners practising biodynamic methods is much greater.

Demeter International

Demeter International is the body that sets the standards for certification. To join Demeter is to join a worldwide family of biodynamic organic farmers, growers, artisan food producers, and manufacturers. Demeter International is committed to developing its standards and promoting the Demeter brand; supporting its licensees; providing a resource base for Demeter certified ingredients etc.; and furthering the work of Biodynamics. Its headquarters are in Darmstadt, Germany.

Demeter is the only ecological association that has built up a network of individual certification organisations world-wide. The full scope of its work can be found here.



In Spring 2011 Patrick Holden CBE agreed to be Patron for the Biodynamic Association. He has a long association with biodynamics, having spent a year on the biodynamic course at Emerson College.

He was formerly the Director of the Soil Association; he is currently Director of the Sustainable Food Trust, which he founded in 2011.

The Biodynamic Association has been instrumental in bringing about the Seed Co-operative, which is dedicated to ensuring a resilient and sustainable food future through seeds. Open pollinated seeds adapt to their local conditions and changes in climate through natural processes due to inherent genetic biodiversity.

We work in three main themes:

  • Producing biodynamic and organic vegetable, herb and flower seed, and developing a network of seed growers.
  • Breeding new varieties of vegetable seed for organic and biodynamic farming.
  • Sharing knowledge and skills about seed saving, plant breeding and the importance of seed and food sovereignty.

Seed Co-operative is the trading name of Biodynamic and Organic Plant Breeding and Seeds Ltd, which is registered under the Co-operative and Community Benefit Societies Act 2014 as a Community Benefit Society. The BDA is a custodian trustee of the Seed Co-operative.
