In other words, either limestone or burned lime may bo used, provided the limestone is reason- ably pure and is finely ground, and ])r()- vided it is kept in mind that 100 pounds of limestone equal fifty-six pounds of lime oxide. Slaked lime also may be used. As said above, slaked lime is formed when water combines with the lime oxide. Air-slaked lime is formed when the oxide is exposed to air. In the case of air-slakestone. It is, therefore, more effective ill producing available nitro- gen (luickly. However, since its ac- tion is rai)id, quicklime must be used with caution. It should not be mixed with manure or other organic fertil- izers, such as dried blood or tankage, for the nitrogen in these substances is liberated rapidly, as a result of the ac- tion of the quicklime, and thus it may be lost before the plant can use it. The effects of overfeeding with nitro- gen may also naturally follow. The same rule applies also if ammonium sidphate is used as a fertilizer. In order to hasten decomposition of ma- nure, quicklime may be used in small quantities, but in this case the lime should be added before the plants are l>nt in the soil and precautions should lie taken to prevent the loss of the nitro- gen. What to Avoid. Lime in any form should not be mixed with or applied at the same time with acid phosphate. This is because the lime tends to change the water-soluble |ihosplioric acid to an insoluble form, s
