ni·tri·fy

 (nī′trə-fī′)
tr.v. ni·tri·fied, ni·tri·fy·ing, ni·tri·fies
1. To oxidize (an ammonia compound) into a nitrite or (a nitrite) into a nitrate, especially by the action of nitrifying bacteria.
2. To treat or combine with nitrogen or compounds containing nitrogen.

nitrification

(ˌnaɪtrɪfɪˈkeɪʃən)
n
1. (Biochemistry) 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
2. (Chemistry)
a. the addition of a nitro group to an organic compound
b. the substitution of a nitro group for another group in an organic compound

ni·tri·fi·ca·tion

(nī′trə-fĭ-kā′shən)
The process by which bacteria in soil oxidize ammonia and form nitrates and nitrites. Because the nitrates and nitrites can be absorbed by the roots of green plants, nitrification is an important step in the nitrogen cycle.
