What does Calcium Carbonate (CaCO3) mean?
Calcium carbonate is a white mineral that occurs naturally in chalk, limestone, and marble, and is the main mineral that forms mollusk shells, stony corals, and pearls.
For horticultural purposes, calcium carbonate is most often used to produce a more alkaline soil, usually through the application of lime.
Calcium carbonate is an important trace element for plants. It can help the soil convert nutrients into a more usable form.
Calcium carbonate in the form of lime has many uses, including:
- To raise the pH of acidic soil in order to “sweeten” it.
- As a deodorizer in stables, barns, and greenhouses.
- As a bacterial disinfectant.
- In wastewater treatment to raise the pH and produce more favorable alkaline conditions.
