उत्तर
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.
