Under warm growing conditions, NH4+ in the soil will be transformed to NO3- via nitrification. WebDenitrification — the process by which bacteria convert nitrate (NO3–) to nitrogen gas (N2), which is lost to the atmosphere. Denitrifying bacteria use NO3– instead of oxygen in their metabolic processes when the soil atmosphere lacks oxygen.
