Calcite Calcium - Greensmiths

The solubility of calcium carbonate is affected by the purity of the calcium and the crystal structure as well as the fineness of grind. Very fine ground calcium carbonate raises pH very quickly. Dr. Albrecht studied calcium function in the soil and determined that powdered calcium raised the pH excessively and leached readily.
