Welcome to Demeter USA. We are the non-profit American chapter of Demeter International, the world's only certifier of Biodynamic® farms and products. Biodynamic agriculture goes beyond organic, envisioning the farm as a self-contained and self-sustaining organism. In an effort to keep the farm, the farmer, the consumer, and the earth healthy, farmers avoid chemical pesticides and fertilizers, utilize compost and cover crops, and set aside a minimum of 10% of their total acreage for biodiversity. The entire farm, versus a particular crop, must be certified, and farms are inspected annually. In order for a product to bear the Demeter logo it must be made with certified Biodynamic® ingredients and meet strict processing standards to ensure the purest possible product.
