Biodynamic techniques draw on the work of Austrian spiritual teacher Rudolf Steiner in the early years of the last century. He felt it was vital to reconnect growers to the spiritual aspects of growing as a counter balance to the increasing dominance of mechanistic models of food production. Biodynamic growers build up the spiritual strength of their land, crops, animals and themselves through the use of special kinds of compost and organic sprays and through working with the phases of the moon and the planets. They see every farm or garden as a holistic organism with it own spiritual identity.
