What is considered the common liming material with the formula CaCO3?

The common liming material with the formula CaCO3 is known as calcitic limestone. This compound primarily consists of calcium carbonate, which is essential for neutralizing soil acidity and improving soil pH. When applied to agricultural land, calcitic limestone helps to enhance nutrient availability and overall soil health, facilitating better crop yields.

Hydrated lime, while also used for liming, is chemically different as it is derived from calcium hydroxide (Ca(OH)2). Dolomitic limestone contains both calcium carbonate and magnesium carbonate (MgCO3), making it distinct from pure calcitic limestone. Calcium silicate is used for soil amendment, but it is not composed of calcium carbonate. Understanding these distinctions is vital for making informed nutrient management decisions in agriculture.
