Why does denitrification of bacteria occur?
Asked by avsk53 | 15 Mar, 2017, 01:30: PM
Expert Answer
Hi Abhiram,
Denitrification is a natural soil microbial process where nitrate (NO3 -) is converted to nitrogen (N) gases that are lost to the atmosphere. When the oxygen (O2) supply in soil becomes limited, a variety of bacteria use the oxygen in nitrate for respiration. Denitrification most commonly occurs in wet or waterlogged soils where the oxygen supply for respiration is restricted.
