The nitrogen cycle involves the fixation of atmospheric nitrogen into ammonia, nitrification of ammonia to nitrates, assimilation of nitrates by plants, and denitrification of nitrates back to nitrogen gas.
Il ciclo dell'azoto comporta la fissazione dell'azoto atmosferico in ammoniaca, la nitrificazione dell'ammoniaca in nitrati, l'assimilazione dei nitrati da parte delle piante e la denitrificazione dei nitrati in azoto gassoso.
