WebIn addition, human activities would change the nitrogen cycle base on different factors. Nitrogen would increase with the increases of fossil fuel combustion. Due to the process, would transfer fixed nitrogen from long-term geological reservoirs to the atmosphere. WebHumans have a huge impact on the nitrogen cycle. There are two major factors that we do to contribute; burning fossil fuels and using nitrogen based fertilizers. By burning fossil fuels and using these fertilizers there are great changes in the amount of nitrogen in the atmosphere that alter the water and land ecosystems.

WebHuman impact on nitrogen cycle: The nitrogen cycle is influenced by a variety of human activities. The amount of biologically accessible nitrogen in an ecosystem can be greatly increased by burning fossil fuels, applying nitrogen-based fertilisers, and other activities.
