Limestone To Calcium Carbonate Ratio

Gardening Calculators: Limestone

Gardening Calculators: Limestone

What is limestone? When gardeners talk about "lime" or "limestone," they mean either calcium carbonate (calcite or calcitic limestone), or calcium-magnesium carbonate (dolomite or dolomitic limestone). Of the two forms, dolomite is preferred as it provides magnesium as well as calcium.

Jul 07, 2017 · When limestone is heated, the calcium carbonate is decomposed as per the following equation. CaCO3 + around 42.5 kcal of heat = CaO + CO2. Around 1.8 t of limestone is required to produce 1 t of quicklime. The quicklime is not stable. In the presence of moisture, lime reacts slowly with carbon dioxide in the air, reforming calcium carbonate.
