What are the harmful effects of chemical fertilizers?
Answer:
Chemical fertilizers provide minerals which dissolve in water and are immediately available to plants. But they may escape from the soil and pollute the groundwater, rivers and lakes. Chemical fertilizers can also kill bacteria and other micro-organisms in the soil. It means sometimes, after their use, the soil will be less fertile than ever before. So, continuous use of chemical fertilisers has led to the degradation of the soil’s health.
