This proves the truth of the principles of Vertical Farming, which aims to cultivate downward as well as to till the top soil. Three years ago tree planting in blasted holes was experimental— now millions of trees are set out by the Vertical Farming method every spring and fall. In like manner, blasting the subsoil to increase general crop yields, now regarded as experimental, will in a few years, be common. To learn how and why Vertical Farming may double the yields of your farm, get the Free Heading Course in Vertical Farming, by Dr. G. E.
