Question

Which of the following properties differentiates fertilisers and manure?

• A. Better crop yield
• B. Water Pollution
• C. Rich in nutrients
• D. None of the above

Answer 1

The correct option is B

Water Pollution

Adding manure is a natural way of increasing soil fertility and in turn, increasing yield. Fertilisers are artificially synthesised inorganic salts which also increase yield. Excessive use of fertilisers may result in their runoff into the nearby water bodies, resulting in water pollution. Increase in nitrogen content in water bodies lead to algal bloom and disrupts the delicate balance of aquatic life.
