LIME.
This is a valuable application to the soil. For wheat it is very important, except on soil containing a large proportion of calcareous matter. Usually air-slaked, and applied as a top-dressing, or plowed or harrowed in, its effects are important. On moist, sour land, producing wild grass, it corrects the acidity, introduces other grass, and prepares the soil for cultivation. On hard, stiff lands, it has a tendency to make them friable, and keep them in a mellow condition, thus saving more than its cost, in the labor of cultivation. Very valuable in a compost heap. So much may be applied as to burn the soil and prove injurious. It will not do as a substitute for everything else. See further on "Manures."
