GeneralClass 12AllAnswered 27 Mar 2026
Answer
Denitrification is the microbial reduction of soil nitrates (NO₃⁻) to gaseous forms of nitrogen (N₂, N₂O), which are released into the atmosphere. This process reduces soil fertility by depleting available nitrogen.
Microbes Responsible:
- Pseudomonas denitrificans
- Thiobacillus denitrificans
Denitrification typically occurs under anaerobic conditions in waterlogged soils.
