Question 5

When the soil is too basic in nature, plants do not grow well in it. To improve its quality what must be added to the soil?
(a) Organic matter
(b) Quicklime
(c) Slaked lime
(d) Calamine solution

Answer 1

Correct option is (a)

If the soil is too basic, acidic substances should be added to neutralise the pH of the soil. Manure or compost also called organic matter must be added to soil because they release acids that react to neutralise excess bases present in the soil and thereby reduce its basic nature and improve soil fertility.
