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 1)ottom nf the furr^/iw, thus interfering with the capillary moisture. Second, weeds alsci utilize a large amoimt of available plant fijod, 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 is, crosswise of the way the stalks are laying. In case of heavy stalks, the discs, even if \'ery heavy and sharp, will often ride over if they are piled deeply between the rows. The
