Corn. 142 CORN of moisture, but that moisture which does rise is held just below the surface; Second, this moisture being present keeps the soil from dry- ing out, and when turned over by the mold board the soil crumbles and falls into the furrow loosely. Third, the surface which has been previously fined now becomes the bottom of the furrow slice, which because of its structure reunites with the several capillary tubes, thus re-establishing the course of the moisture BREAKING PLOW. Used in plowing sod. Notice that the moldboard is very sloping. Weeds and grass allowed to grow up in corn-stalk land in the spring, before plowing, are first injurious to the physical condition of the soil because they compact and harden the surface, which in turn allows the rapid evaporation of moisture. When this green mat is turned under later, it acts as a partition between the furrow slice and the bottom of the furrow, thus interfering with the capillary moisture. Second, weeds also utilize a large amount of available plant food, and at the same time the decaying green material renders the soil more or less acid. Rotting green manure requires a great deal of moisture which must necessarily be drawn from the sur- face soil. Often the furrow slice becomes very dry within a few days. Two methods of discing are practiced. By one, the field is disced with the stalks standing. In such cases, the disc is driven at an angle to the rows across the field. The ridges are leveled and the stalks cut to pieces. The other plan, the one usually practiced, is to harrow or drag the stalks down and then disc them crosswise of the row; that iSj crosswise of the way the stalks are laying. In case of heavy stalks, the discs, even if very heavy and sharp, will often ride over if they are piled deeply between the rows. The advantage of the first method is becoming apparent to Please note that these images are extracted from scanned p
