What does nitrify mean?
Nitrify is a technical verb used mainly in biology and environmental science to describe the conversion of ammonia or ammonium into nitrites and nitrates. This transformation is carried out by specialized microorganisms and forms an important part of the nitrogen cycle. Because nitrate is a form of nitrogen that most plants can absorb, nitrification helps make nutrients available in soil and supports plant growth. The verb can be used transitively, as in “bacteria nitrify ammonia,” and intransitively, as when a material undergoes the process in a treatment system. In general writing, “nitrify” is more precise than saying merely that something is “converted,” because it identifies a specific biochemical process involving nitrogen compounds.
To convert ammonia or ammonium into nitrites or nitrates, especially through microbial action.
"Nitrifying bacteria convert ammonia into nitrite in the treatment tank."
Used chiefly in biology, microbiology, agriculture, and environmental science.
To undergo conversion into nitrites or nitrates.
"The nitrogen compounds nitrify as the organic material breaks down."
This intransitive use is especially common in descriptions of soil, wastewater, and environmental processes.
Every bite of natural nitrogen in much of the world’s food supply begins with microorganisms quietly turning ammonia into a form plants can use.
