For thousands of years the moon has served us as a brilliant calendar, although in recent times we've relied on more convenient clockwork devices. We know that the moon controls the tides, regulates our periods; some farmers even plant their crop in tune with its phases (it's called Biodynamic Gardening).
Essentially the pull of the moon affects how fast or slow things here on planet earth will grow. Rudolf Steiner, founder of the biodynamic approach to agriculture, was the first to point to the danger of synthetic fertilizers, which were just appearing in his time. He was also the first to bring the perspective of the farm as a single, self-sustaining organism that thrives through biodiversity, the integration of crops and livestock and the creation of a closed-loop system of fertility.
Steiner also brought forth a unique and comprehensive approach to soil, plant, animal, and human health that recognizes the importance of the healthy interplay of cosmic and earthly influences. With this knowledge, he developed a set of homeopathic preparations used by biodynamic farmers on soil, compost, and plants that help build up the farm's innate immune system and vital forces.
