nitrification

• 硝化作用：将硝基引入有机化合物的化学反应；也指土壤细菌将铵盐或死亡有机物质中的氨氧化为亚硝酸盐和硝酸盐的生物过程，使氮能被植物利用。

A chemical process in which a nitro group is added to an organic compound, or the biological oxidation of ammonium compounds in dead organic material into nitrates and nitrites by soil bacteria, making nitrogen available to plants.
