2. Treatment of a material with nitric acid.

nitrification

the conversion by soil BACTERIA of organic nitrogen into inorganic nitrates which plants can take up. Decay of animal and plant proteins gives rise to ammonium compounds which the bacteria Nitrosomonas and Nitrococcus oxidize to nitrite. Nitrobacter oxidizes nitrites to nitrates. See NITROGEN CYCLE.
