Autores ResumoNitrification and denitrification occur in both “oxidation” and “reduction” layers of the plow horizon of paddy soil during the growth period of rice. The nitrite bacteria obtained from paddy soil oxidize ammonium nitrogen to nitrite nitrogen under anaerobic cultural conditions. It is a facultative anaerobic ecotype of nitrite bacteria and is closely associated with denitrifying bacteria. The close association of nitrifying and denitrifying bacteria provides a free route of conversion of ammonium nitrogen to gaseous nitrogen through nitrite (and nitrate) at the same locus in the soil.
