Ammonification

Ammonification :
Dead plant & animal protein and their waste like urea & uric acid converted to ammonia by some ammonifying bacteria in soil. e.g. Bacillus mycoides, B. vulgaris & B. ramosus etc.
Nitrification :
Ammonia is converted into nitrite by Nitrosomonas bacteria, and Nitrobacter convert nitrite into nitrate. This nitrate again can be absorbed by plant & thus cycled back.
Denitrification :
Some denitrifying bacteria like Pseudomonas reduce nitrate into nitrogen gas in soil. This gas is again back to environment.
