One of the methods unique to biodynamic agriculture is the use of the biodynamic preparations.  Horns filled with manure? Grinding up quartz crystals?  It can be hard to know where to start. 

This course covers everything from the basics of what the biodynamic preparations are, how to make and use them all the way through to research, both quantitative and qualitative, that explore their effectiveness.

This self-study course is designed for anyone who is interested in the preparations, for farms, gardens, or allotments.  All that is required is interest, a decent internet connection and some self-motivation. 

Course Structure

  • Readings – some of these have been written specifically for the course and some are collections of other written resources.

  • Activities – designed to further your engagement and understanding of the subject.

  • Interviews – that present the relationship of a biodynamic farmer or grower with the preparations.

  • Further reading and references – if you want to find out more, we've put together lots of resources and links to research and other resources.

  • Live Q&A with experts – every 4 to 6 weeks we'll hold a live webinar with experts to answer your questions. Recordings of past Q&A sessions are also available to all participants.
