  • Gypsum vs Dolomite vs Calcium Carbonate 420 Magazine

     · Dolomite contains calcium and magnesium and with a medium solubility can quickly treat soil ph corrections. Calcium carbonate is a general term for Lime based buffers and only contains calcium it can be fine (high solubility) or chunky (lower solubility). Gypsum is the least soluble and is used to break up compact Earth.

     · • Calcite mainly contains calcium carbonate and dolomite contains calcium magnesium carbonate. Dolomite differs from calcite because of the presence of magnesium. • Calcite reacts quickly with acids and produce carbon dioxide bubbles. But dolomite is weakly reacts with acids producing bubbles very slowly.
