Explanation:

Acidic soils create production problems by limiting the availability of some essential plant nutrients and increasing that of the soil solution's toxic elements, such as aluminum and manganese, the major cause of poor crop performance and failure in acidic soils.
Soil acidity can be corrected easily by liming the soil, or adding basic materials to neutralize the acid present.
The most commonly used liming material is agricultural limestone, the most economical and relatively easy to manage source.
The limestone is not very water-soluble, making it easy to handle.
As lime dissolves in the soil, calcium (Ca) moves to the surface of soil particles, replacing the acidity. The acidity reacts with the carbonate (CO3) to form carbon dioxide (CO2) and water (H2O). The result is a soil that is less acidic (has a higher pH).
