Biodynamic Agriculture has much in common with Organic agriculture. Both make use of tool such as cover cropping, green manure, crop rotations, inter-cropping, and the regular application of compost. However, biodynamic agriculture adds to those methods, an acute sensitivity to the astronomical calendar for the scheduling of farm activities. In addition, those practicing biodynamic agriculture use herbal and mineral powders to augment their regular compost applications. Rudolf Steiner is credited with the development of Biodynamic agriculture. Below is a sampling of organizations currently promoting and educating about biodynamic agriculture:
