Before the maize is planted, the ground should be made clean and reasonably fine. On good maize soil very deep })lowing is unprofitable. The effect of plowing to different depths was tested in Illinois. On a part of the field which was worked shallowly with a disk-plow, but not turned over, the yield was bushels an acre. Plowed 5 cm deep, the yield was bushels. Plowed 10 cm deep, the yield was bushels. Plowed 15 cm deep, the yield was bushels. Plowed 20 cm deep, the yield was bushels. In this case it was unprofitable to plow more than 10 cm deep. But in an experiment in Cebu, very deep plowing (subsoiling) almost doubled the 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 Copeland, Edwin Bingham, 1873- [from old catalog].
