| nitrification | 1. <chemistry> The act, process, or result of combining with nitrogen or some of its compounds. The act or process of oxidizing nitrogen or its compounds so as to form nitrous or nitric acid. 2. A process of oxidation, in which nitrogenous vegetable and animal matter in the presence of air, moisture, and some basic substances, as lime or alkali carbonate, is converted into nitrates. The process is going on at all times in porous soils and in water contaminated with nitrogenous matter, and is supposed to be due to the presence of an organised ferment or ferments, called nitrification ferments. In former times the process was extensively made use of in the production of saltpeter. Origin: Cf. F. Nitrification. See Nitrify. Source: Websters Dictionary (01 Mar 1998) |

the chemical process in which a nitro group is added to an organic compound (or substituted for another group in an organic compound) the oxidation of ammonium compounds in dead organic material into nitrates and nitrites by soil bacteria (making nitrogen available to plants)

| nitrification |
An aerobic process in which bacteria change the ammonia and organic nitrogen in wastewater into oxidized nitrogen (usually nitrate). The second-stage BOD is sometimes referred to as the "nitrification stage" (first-stage BOD is called the "carbonaceous stage").
