Biodynamic Agriculture, by Willy Schilthuis. Based on the work of Rudolf Steiner, Biodynamics is an internationally recognized approach to organic agriculture which respects and works with the spiritual dimension of the Earth. Where conventional agricultural methods threaten the environment, biodynamic farms and gardens are designed for sound ecological balance. This concise, fully illustrated book presents evidence that biodynamic crops have deeper roots and stronger disease resistance and keep better than conventionally produced crops. Schilthuis was president of the Dutch Biodynamic Association for 25 years. Revised edition.
