why quick lime and slaked lime is added to soil

if the soil is too acidic (having low ph), then it is treated with materials like quick lime (calcium oxide) or slaked lime(calcium hydroxide) or chalk ( calcium carbonate). all these materials are bases and hence react with the excess acid present in soil and reduce its acidity. thus, a farmer should add lime ( or slaked lime or chalk) in his fields when the soil is too acidic.

dear frnd i hope it is clear to u nw.
