nitrogen . Proses ini dilakukan oleh dua jenis bakteria yang dikenali sebagai Nitrosomonas sp. dan
Nitrobacter sp.

Nitrification is the biological transformation of ammonia or ammonium ions into nitrate in nitrogen cycle.
It is facilitated by two types of bacteria known as Nitrosomonas sp. and Nitrobacter sp.

(b) Nitrosomonas sp. menukarkan ion ammonium atau ammonia kepada nitrit manakala
Nitrobacter sp. menukarkan nitrit kepada nitrat di dalam tanah.
