Lime (calcium oxide) and slaked lime (calcium hydroxide) are both used to reduce the acidity of soil on land, they are both faster and stronger acting than limestone powder. Plants grow best within a certain pH range, over acidity can affect plant growth, adding powdered limestone or lime to the soil neutralises the acid and raises the pH to improve crop growth.
