Nitrogen is returned to the atmosphere during the nitrogen cycle through denitrification.

  • Nitrogen is cycled in nature from the atmosphere to living organisms and to the soil. The nitrogen cycle involves the means by which nitrogen is utilized and released in nature.

  • The process that release nitrogen back to the atmosphere is called DENITRIFICATION. Denitrification is the process by which certain microbes in the soil convert nitrate and nitrite to atmospheric nitrogen.
