The practical side of using rockdusts as fertilizers, compost enrichers, and plant growth enhancers is discussed in this exciting book from Acres U.S.A. Beginning with an explanation of the spiritual, cosmic side of rocks and drawing from his extensive knowledge of biodynamic techniques and dowsing, Lisle explains how to utilize these materials in agriculture. Peppered with in-depth quotations from other writings on the forces within rocks, this is destined to be the definitive work on the subject. Life's tenuous connections to the cosmos is a concept almost all literate people think they understand. And yet the principles that enliven the engine of photosynthesis remain as elusive as our perceived comprehension of nature's tap into the Sun. Standing on the shoulders of giants ─ Rudolf Steiner, Julius Hensel, von Helmont, Phil Callahan, and dozens more ─ Harvey Lisle has captured for us both the physical and spiritual connection that links rock powders to life, to agriculture, to cell and plant development. By taking crop production away from a single-factor analysis, Lisle has performed on par with the great innovators and has caused us all to consider anew the sacred text: "Dust thou art, and into dust thou shalt return."
