The way they treat soil is to put down fertilizer containing nitrogen, phosphorous, and potassium. That will allow crops to grow and LOOK good so that people will buy them. But so what? So they put back nutrients which will allow crops to sprout and LOOK good. But what about the rest of them? That's where the problem is. What about the magnesium, manganese, chromium, selenium, calcium, iron, copper, zinc, etc.? They don't put them back. Why? Well, maybe because it would cost too much. So what's the answer? Well, maybe the Journal of the American Medical Association provided the answer. They now recommend that doctors advise their patients, even the healthy ones, to take vitamin and mineral supplements. Well, at least someone has finally opened up their eyes and recognized that there is a problem in our diet.
