nitrificationn.

Brit.

/ˌnʌɪtrᵻfᵻˈkeɪʃn/, U.S.

/ˌnaɪtrəfəˈkeɪʃ(ə)n/

Origin: A borrowing from French. Etymon: French nitrification.

Etymology: < French nitrification (P. Thouvenel Climat d'Italie (1797) IV. 189) < nitrifier nitrify v. (see -fication suffix). Compare Italian nitrificazione (1834).

a. Chemistry and Biology. The process of nitrifying; the production of, or conversion of a substance into, nitre or nitrates; spec. the process by which certain soil bacteria oxidize ammonia in decomposing material into nitrates.
