What is the term used to describe the process of adding lime to soil to raise the pH?

Liming is the process of adding lime (calcium carbonate) to the soil in order to increase its pH level and reduce its acidity. This is often necessary in areas where soil naturally has a low pH, or has become acidic due to excessive use of nitrogen fertilizers or other factors.

The addition of lime raises the soil's pH by reacting with the acid present in the soil, which releases hydrogen ions and replaces them with calcium ions. This reduces the acidity of the soil and makes nutrients more available to plants.
