The Pfeiffer Center at Threefold Community Farm in Chestnut Ridge, NY, offers the biodynamic course for the 27th year in a row. This year-long part-time training covers the basic principles of biodynamic agriculture according to the seasons, in thirteen full-day workshops.

In the classroom, Mac Mead, and expert guest faculty introduce and explain Rudolf Steiner’s spiritual science, the foundation of biodynamics, in the context of Steiner’s “Agriculture Course” of 1924.

In the field, gardening techniques are demonstrated and practices include making and using the biodynamic preparations, compost making and soil building, working with large animals, beekeeping, greenhouse work, and much more.
