Biodynamic Preparations

The use of the preparations is a requirement of the Demeter Biodynamic® Farm Standard.  There are nine in all (although members are encouraged to expand on this list based on the needs and opportunities present on their own farms), made from herbs, mineral substances and animal manures, that are utilized in field sprays and compost inoculants applied in minute doses, much like homeopathic remedies are for humans.  Timely applications revitalized the soil and stimulate root growth, enhance the development of microorganisms and humus formation, and aid in photosynthetic activity.
