प्रश्न
How does chemical nature of the soil change due to continued use of chemical fertilizers ?
Advertisements
उत्तर
Use of chemical fertilisers improve soil fertility for a short duration of time. Continued use of chemical fertilisers cause environmental hazards and lead to the destruction of soil fertility. The increased use of chemical fertilisers cause death of soil microorganisms by making the soil toxic for them. Excessive fertilisers added to the soil end up in the nearby water bodies and increase the nutrient content of the water. This leads to algal bloom.
