Definitions
n.名词 noun
- 1
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.
Examples
This loss of nitrogen by denitrification can be checked by keeping the soil well ventilated.
The conditions which favour denitrification are exactly the opposite of those which favour nitrification.
There will be some loss of nitrogen through leaching and denitrification.
