USE OF THE PREPARATIONS

A distinguishing feature of Biodynamic agriculture is the use of nine preparations 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 revitalize the soil and stimulate root growth, enhance the development of microorganisms and humus formation, and aid in photosynthetic activity.
