How does the use of fertilizer affect the nitrogen cycle? make the answer short

Answer 1

The use of fertilizers can significantly impact the nitrogen cycle by introducing excess nitrogen into the ecosystem. This can lead to nutrient runoff into waterways, causing algal blooms and water quality issues. Additionally, over-fertilization can disrupt natural nitrogen transformations, increase nitrous oxide emissions (a potent greenhouse gas), and alter soil microbial communities, affecting overall soil health and biodiversity.
