What is one consequence of improper fertilizer application?

Improper fertilizer application can lead to water pollution, which is a significant environmental concern. When fertilizers are applied excessively or inaccurately, nutrients such as nitrogen and phosphorus can leach into the water supply. This runoff can lead to eutrophication, a process in which nutrient overloads promote excessive aquatic plant growth, leading to oxygen depletion in water bodies. The resulting low oxygen levels can be detrimental to fish and other aquatic organisms, disrupting ecosystems.

In contrast, applying the correct amounts of fertilizer can support healthy crop growth and improve soil structure, while also helping to manage pests effectively. However, these positive outcomes are compromised when fertilizers are misapplied, highlighting the importance of proper application practices in agricultural settings to minimize environmental impacts.
