About a dozen years ago I heard a farmer present the results of his work on his decades-old biodynamic farm in Australia. He showed slides of the massive pit they had dug in which they laid dozens of cow horns filled with manure, which were used to “enliven” the fields. He shared how they made the biodynamic preparations that are at the heart of the biodynamic process. These preps stimulated calcium uptake by the plants, as well as root and fruit development, and others strengthened the plants against various diseases. But the main thing that stuck with me were the slides he showed of an insect on his farm that had been declared extinct a decade earlier.
