What is one consequence of over-fertilizing crops?

• A. Improved plant growth
• B. Water pollution
• C. Increased biodiversity
• D. Reduced soil acidity

Answer: (B)

One significant consequence of over-fertilizing crops is water pollution. When fertilizers are applied in excess, the nutrients, particularly nitrogen and phosphorus, can leach into nearby water bodies through runoff or percolation. This nutrient overload can lead to a range of environmental issues, including eutrophication, where excessive nutrients in the water stimulate algal blooms. These blooms deplete oxygen levels in the water, harming aquatic life and leading to dead zones where few organisms can survive.

This environmental concern emphasizes the importance of managing fertilization practices to prevent negative impacts on water quality and aquatic ecosystems, highlighting the balance needed in agricultural practices to maintain both crop health and environmental integrity.
