FOWLER. 87 FIG. 69. DEEP PLOWING MAKES BIG CORN YIELDS One of the first experimenters with dynamite for deep plowing was J. H. Caldwell, of Spartanburg, S. C. He subsoiled a portion of his corn-field with dynamite and increased the yield one-third over that of the portions not subsoiled. A committee of the Chamber of Com- merce of Spartanburg inspected this corn and certified to the accuracy of the figures. Effects of Subsoiling With Red Cross Dynamite on the Action of Commercial Fertilizers Co...mmercial fertilizers are ordinarily added to the soil in a very fine and readily soluble condition, and are usually incorporated with the first few inches of soil at or just before the time of seeding. This keeps them from being carried further into the soil mass through cultivation. During heavy rains when there is a considerable amount of surface run-off of the excess of water, large parts of the fertilizers thus added are at once brought into solution and lost by being carried away by the surface drainage.
