Nitrification and nitrifiers in acidic soils
WebbThe third stage, nitrification, also occurs in soils. During nitrification the ammonia in the soils, produced during mineralization, is converted into compounds called nitrites, NO 2 −, and nitrates, NO 3 −. Nitrates can be used by plants and animals that consume the plants. Webb25 mars 2011 · The focus is on the specific factors associated with soil that influence …
