. Elementary principles of agriculture; a text book for the common schools. Agriculture. Fig. 40. Diagram to illustrate the effect of ideal plowing. The compactness of the soil is indicated by the density of the shading. Before plowing, there is a compact surface crust (s), below which the soil grows less compact as we go deeper; after plowing, this compact mass is broken up into a loose, friable mass of soil-crumbs, or floccules, with a consequent increase in the bulk of the furrow-slice (fs); compacted plow sole at pi.
