denitrification

[ dee-nahy-truh-fi-key-shuhn ]
/ diˌnaɪ trə fɪˈkeɪ ʃən /

noun Chemistry.

the microbial process in which nitrates and nitrites are reduced or removed from soil, water, or air by their conversion into nitrogenous gases. This process is environmentally significant, as in the treatment of wastewater, which depends on denitrification to eliminate toxic levels of nitrogen, making the water safe for plants and animals. We’re observing the nitrogen activity in salt marsh soil, with a particular interest in the last step of the nitrogen cycle—that is, denitrification.
