Question

What material should be added to a soil which is too acidic? How does this material help in reducing the acidic nature of the soil?

Answer 1

When soil becomes acidic, it is treated with bases such as quicklime (calcium oxide) or slaked lime (calcium hydroxide). (1 Mark). Bases like quicklime (or slaked lime) neutralise the action of excess acid present in the soil. (1 Mark).
Thus, a farmer should add bases like quicklime under acidic conditions of the soil.
