Demeter Certified Biodynamic

All farms must have biological diversity, generating fertility, disease insect and weed control, the use of biodynamic preparations, water and waterway conservation, livestock integration, and gentle post harvest handling. Farms should have self-sustaining fertility dynamics. Composting should also be utilized. "The maximum amount of nitrogen and phosphorous that may be applied by way of fertilizers used, averaged over the crop rotation, may not exceed the amount that would be produced by those! animals which the farm could support by its own irrigated (if necessary) forage production". The use of imported fertility should be limited
