Question

What should be added in the soil when it is: (i) too acidic (ii) too basic? Discuss your answer.

Accepted Answer

(i) Acidic soil can be treated by mixing of bases such as quicklime (calcium oxide) or slaked lime (calcium hydroxide). These bases neutralise the excess acids present in the soil and hence soil becomes neutral.

(ii) When soil becomes too basic, basic soils are neutralised by adding large quantities of acidic substances like composted manure. Manure releases acids which neutralise the basic nature of the soil. Most plants grow best in neutral soil, but excessive use of fertilisers makes the soil either acidic or basic. This affects the growth of plants, thereby affecting productivity adversely.
