used by plants. Calcium is commonly applied as a soil amendment in the form of ground limestone (calcium carbonate) or gypsum (calcium sulfate) (Hodges 2010). Water-soluble calcium (WCA) is an alternative to these commercial sources of calcium. This fact sheet ad-dresses frequently asked questions about making WCA and its use in Natural Farming.

Although precision is crucial, the manufacturing process itself is simple. First, Graymont takes the finest lime available, which is calcium oxide, custom made for this process at one of the Company's facilities. The calcium oxide is mixed with water and pumped to the reaction vessel. CO2 rich gas is then introduced into the mix to produce PCC.

Drinking water is often treated with lime to soften water by removing carbonate and other anions that contribute to hardness. A typical chemical reaction for softening (removing calcium carbonate hardness) is given by Ca 2+ + 2HCO 3 + Ca(OH 2) = 2CaCO 3 (s) + 2H 2 O This reaction shows the formation of calcium carbonate (CaCO 3).
