Harvey begins by explaining the spiritual, cosmic side of rocks and drawing on his extensive knowledge of biodynamic techniques he explains how to utilize these materials in agriculture. This is the definitive book on this subject. After reading Enlivened Rock Powders you'll feel compelled to put more back into your soil than N,P & K. If you have ever noticed how plants near the edges of fields located on gravel roads do better than those in the center of the field you are started down the path of recognizing the spiritual connection that links rock powders to life, agriculture and plant development.
