differentiate between nitrogen fixation and denitrification..
Nitrification is the process of conversion of ammonia into nitrates and then into nitrites. This is done by nitrifying bacteria like nitrosomonas and nitrobacter.
N2 ----------------------> NH3 --------------------> NO2 ------------------------> NO3
Ammonification Nitrification Nitrification
Denitrification is the process of reducing the nitrates present in the soil to release nitrogen gas back into the atmosphere.
NO3 ---------------------------> N2
