Phonetic (Standard)IPA

noun

Chemistry, Biology.

the process of oxidation in the nitrogen cycle that converts ammonia or ammonium compounds to nitrites and then to nitrates, especially this process as facilitated by bacteria and other microbes in soil to provide the nitrogen vital to plant health and growth.

the oxidation of the ammonium compounds in dead organic material into nitrites and nitrates by soil nitrobacteria, making nitrogen available to plants See also nitrogen cycle
