NO practical or useful information
on February 9, 2011
I bought this book because I am a gardener and am always interested in new, possibly useful ways to garden better. I believe in the role of energy and frequencies in enhancing health, so I was hoping to find something useful to add to my knowledge. Unfortunately, there is NONE in this book, in spite of the author believing it will "save the world's agriculture". He has proven through his experiments that energies exist. He has created a $400 meter to measure them (which obviously is much better than the existing $4,000 meters for the average gardener or farmer). He says these energies exist in SOME rocks, particularly volcanic ones, but that they vary significantly based on the origin of the rock, so you can't just buy granite dust or Azomite or whatever and put it on your garden and expect results. He says that 60-70% of the world's agricultural land is deficient in this energy, which is required to release the nutrients in the soil. But most of the book is about how he discovered and measures these energies, pretty much Greek if you don't understand radio waves, etc. I kept waiting for his conclusions or recipe or recommendations about how to use this information, but it never came.
I think Dr. Callahan is/was a fascinating person and that he probably made a major contribution by trying to reconnect chemistry, physics and biology as they relate to agriculture. But as a gardener, I found this book to be totally useless.
