Nitrogen Cycle (Source: Commons)[/caption]A. Aminization : Hydrolytic decomposition of proteins & release of amines and amino acids (In absence of oxygen)
B. Ammonification: Organic N into amino acids into ammonia (hydrolatic and oxidative rxns. in presence of oxygen)
C. Nitrification: Conversion of ammonia to nitrites NO2 & then to nitrates
NH3 to NO2- (Nitrosomonas)
NO2- to NO3- by (Nitrobactor)
***Ammonia : toxic to plants***
***ammonia contained ground water results methamoglobinmia (blue baby syndrome) : if used as drinking water***
***30 to 35 degree C; pH 6.5 to 7.5***
***Activity of Bacteria ceases below pH 5.0***
*Denitrification: Conversion of soil nitrate into gaseous nitrogen or nitrous oxide. Water logging and high pH increases Nitrogen Loss.
By Pseudomonas and Paracoccus (anaerobic conditions)
