What is a potential consequence of overapplying fertilizers?

Overapplying fertilizers can lead to water pollution, which is a significant environmental concern. When excess fertilizers are applied to crops, not all of the nutrients are absorbed by the plants. The surplus can runoff during rain events, carrying nitrogen and phosphorus into nearby water bodies. This runoff contributes to nutrient loading in streams, rivers, and lakes, leading to issues such as algal blooms. These blooms can deplete oxygen levels in the water, causing harm to aquatic life and disrupting ecosystems. Additionally, contaminated water sources can pose health risks to humans and animals. Effective management of fertilizer application is crucial to minimize these unintended consequences and protect water quality.
