DEPTH OF CULTIVATION 183 an almost impervious sub-surface strata. As more humus is intro- duced into these soils, the surface cultivator may come into more practical usefulness for laying by corn. From the results of an experiment conducted in Indiana for five years, the average yield of corn was bushels per acre for the shal- lovir cultivation, (1 to 3 inches) and bushels where cultivated four inches deep. This experiment extended over a period of eight years with the one, two and three-inch cultivations, and five years with the four- inch cultivation. It will be seen that there was a decrease in the yield when the cultivation exceeded the depth of three inches. This exper- iment has been corroborated by the Iowa Experiment Station and in some parts of this state by farmers who have paid special attention to this investigation. A similar experiment was conducted at the Ohio Station* and the results of a ten-year test showed an average yield of bushels per acre and 2661 pounds of stover from deep cultivation, as compared with bushels of grain and 2874 pounds of stover per acre from the shallow cultivation. The double shovel was used in the deep cul- tivation, and the spring tooth cultivator in the shallow SURFACE CULTIVATOR These shovels are made to pulverize the surface rather than stir to any considerable depth 'Ohio Bulletin No. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bowman, Melville Le Roy, 1881-.
