Question

Among the given options, which one is not correct for the use of large amounts of fertilisers and pesticides?

Options

  • They are eco-friendly

  • They turn the fields barren after some time

  • They adversely affect the useful component from the soil

  • They destroy the soil fertility

MCQ

Solution

They are eco-friendly

Explanation:

Fertilisers and pesticides are not eco¬friendly, in fact, they are considered as a source of air, water and soil pollution. Excessive use of fertilisers can turn the soil acidic or alkaline and affects the fertility of the soil. Prolonged use of fertilisers can destroy soil fertility by killing the microorganisms that form humus. The soil may become unable to sustain plant life and ultimately become barren.
