Question

Fertilizers are good for crops but cause pollution. Explain

Answer 1

Fertilizers are good for crops but cause pollution. This becoz excess use of fertilisers causes land pollution. Increase in the use of fertilizers have various negative effects on the soil of the area where they are applied. Some of the ways in which they harm the soil fertility are: 1) They alter the soil chemistry and may make the soil acidic or alkaline which adversely affects the soil. 2) They are non biodegradable, hence excessive use leads to soil pollution. 3) They destroy the life present in soil. Excessive amounts kill the bacteria and other decomposers present in soil which are involved in increasing the fertility of the soil by making humus. Therefore, fertility of soil goes down as no more organic matter is there.
