Calcium carbonate, the chief component of limestone, is a widely used amendment to neutralize soil acidity and to supply calcium (Ca) for plant nutrition. The term "lime" can refer to several products, but for agricultural use it generally refers to ground limestone.

Calcite readily dissolves in diluted hydrochloric acid or vinegar. It is also slightly soluble in water, which causes dillution and reprecipitation of calcite along fissures in limestone rocks. These processes lead to the formation of karst landscape with famous caves and dripstones. Similar processes cause the corrosion of concrete.

Limestone Formation. Calcite, dolomite and aragonite are limestone minerals so where did they came from. It is a sedimentary rock. It forms predominantly on the sea floor where material rich in calcium carbonate ('calcareous' material) accumulates. This calcareous material may be organic, chemical or detrital in origin.

Calcite is the primary mineral component of limestone and its metamorphic form, marble. It is very soluble in groundwater and is common in the shells of invertebrates like clams and oysters.
