This work was the first book to attack Von LiebigÕs salt fertilizer thesis, and it stands as valid today as when first written over 120 years ago. Translated from the German writings of Julius Hensel, the book was designed to introduce the people of the U.S. to the idea that plants require healthy food in order to flourish, just as a human being does. It describes a then new and rational system for fertilization which has become science today Ñ fertilizing with stone dust. Hensel went searching for food for plants and found it in the primeval rocks. Fed on such foods, plants will yield healthy, wholesome and life sustaining food that escapes disease and parasites. In the second part of the book "Makrobiotik" Hensel give us a wide range of receipes an cures. The third part opens the chemical wonderworld offering a deep view in the core of all matter.
