Does the use of fertilizer affect the nitrogen cycle?

Question

Olivia Akins · Accepted Answer

No.

We might think that adding specific nitrogen compounds to agriculture would affect the nitrogen cycle. But, it really is just a part of a much larger system as shown by the included graphics.

As a "cycle" the nitrogen is continuously removed from the atmosphere and ground sources, used by plants for growth, and then fixed, immobilized or leached or removed back to the soil or atmosphere.

Andrew Armstrong · Answer

undefined Yes, the use of fertilizer can affect the nitrogen cycle. Fertilizers often contain nitrogen compounds, such as ammonium nitrate or urea, which can increase the amount of nitrogen in the soil. This excess nitrogen can lead to several issues, including leaching into groundwater, runoff into surface water, and emissions of nitrous oxide, a potent greenhouse gas. These effects can disrupt the natural balance of the nitrogen cycle and have negative impacts on the environment.

undefined Yes, the use of fertilizer can affect the nitrogen cycle. Fertilizers contain nitrogen compounds that can increase the amount of nitrogen available in soil. This excess nitrogen can lead to various environmental issues such as nutrient runoff into water bodies, eutrophication, and disruption of natural nitrogen cycling processes.
