“THE MASS DESTRUCTION of soil microorganisms began with technological advances in the early twentieth century. The number of tractors in the U.S. went from zero to three million by 1950. Farmers increased the size of their fields and made cropping more specialized. Advances in the manufacture of nitrogen fertilizers made them abundant and affordable. Ammonium nitrate used in WWII for munitions was then used for agriculture.”
