How do humans impact the nitrogen cycle?

Answer 1

By synthesis of nitrogenpous fertiliser.

The use of nitrogenous fertilizers affects the natural nitrogen cycle. Humans artificially synthesize fertilizers in factories. The most significant nitrogenous fertilizer is urea, which replenishes the depleted nitrogenous supply in the soil. It is first synthesized organically in the laboratory.

Humans impact the nitrogen cycle through activities such as agricultural fertilization, burning of fossil fuels, and industrial processes, which release nitrogen into the atmosphere and disrupt natural nitrogen cycling processes. Additionally, deforestation and urbanization can lead to increased runoff of nitrogen-containing compounds into waterways, causing eutrophication and disrupting aquatic ecosystems.
