A dose of spirituality with your agriculture? Biodynamic agriculture is based on holistic principles developed by esotericist Rudolf Steiner circa 1920s. The farm is viewed as an organism, planting and harvesting are done by the moon chart, and molecularly activated (think homeopathic medicine style) solutions are applied instead of pesticides.
And it’s curing our ruined soil.Which is intrinsically tied to ourselves.
