NH4+ -> Organic nitrogen
Nitrogen uptake
Organic nitrogen -> NH4+
Mineralization
Chemical formula of ammonium nitrification
NH4+ + O -> NO3- + H2O
Nitrification requires
Oxygen
Form of nitrogen not held by soil particles
Nitrate and nitrite
Form of nitrogen held by soil particles
Ammonium
The process by which oxidized forms of nitrogen such as nitrate (NO3-) and nitrite (NO2-) are converted to dinitrogen (N2) and, to a lesser extent, nitrous oxide gas (NO2)
