Certified Biodynamic
Biodynamic agriculture is a method of organic farming originally developed by Rudolf Steiner that employs what proponents describe as "a holistic understanding of agricultural processes". One of the first sustainable agriculture movements, it treats soil fertility, plant growth, and livestock care as ecologically interrelated tasks.
Biodynamics has much in common with other organic approaches – it emphasizes the use of manures and composts and excludes the use of artificial chemicals on soil and plants. Methods unique to the biodynamic approach include its treatment of animals, crops, and soil as a single system; an emphasis from its beginnings on local production and distribution systems; its use of traditional and development of new local breeds and varieties; and the use of an astological sowing and planting calendar. Biodynamic agriculture uses various herbal and mineral additives for compost additives and field sprays.
