Question 8
Among the given options, which one is not correct for the use of a large amount of fertilisers and pesticides?

(a) They are eco-friendly
(b) They turn the fields barren after some time
(c) They adversely affect the useful component of the soil
(d) They destroy the soil fertility

Answer 1

(a) They are eco-friendly

Use of fertilisers and pesticides over a long period of time can destroy the fertility of the soil or soil structure by killing the soil microorganism that recycles nutrients in the soil. It also kills earthworms which are instrumental in making rich humus. Hence, use of a large amount of fertilizers and pesticides is not eco-friendly.
