What can be a consequence of excessive nutrient application?

Excessive nutrient application can significantly lead to increased chances of nutrient runoff into water bodies. When fertilizers are applied in larger amounts than what the soil and crops can absorb, the surplus nutrients become prone to leaching during rainfall or irrigation events. This runoff can carry nutrients, especially nitrogen and phosphorus, into nearby streams, rivers, and lakes.

The consequences of nutrient runoff are severe, contributing to environmental issues such as eutrophication. This process can cause algal blooms, which deplete oxygen levels in water bodies and harm aquatic life. Therefore, understanding the implications of nutrient management not only affects crop yield and soil health but also plays a crucial role in protecting water quality and ecosystems surrounding agricultural areas.
