Transformation from ammonia to nitrate by soil microorganism action ; its made in 2 steps in superficial soil strata : nitrosation by aerobic nitrous bacteria ( Nitrosomonas ) nitration by aerobic nitric bacteria ( Nitrobacter)
The oxidation of ammonia to nitrite and then nitrate by bacteria See also biological filtration
The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate It occurs naturally in surface waters, and can be engineered in wastewater treatment systems The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia
The process by which bacteria converts ammonia into nitrite and then nitrite into nitrate This is the basis of the nitrogen cycle
The conversion of nitrites to nitrates, usually by microorganisms The term is commonly used to describe the process of conversion of ammonium ions via nitrites to nitrates
the biological or chemical transformation of ammonium nitrogen to nitrate nitrogen
bacterial processes that convert ammonia or atmospheric nitrogen to nitrate or nitrite
the oxidation of ammonium compounds in dead organic material into nitrates and nitrites by soil bacteria (making nitrogen available to plants) the chemical process in which a nitro group is added to an organic compound (or substituted for another group in an organic compound)
Nitrification is the process in which ammonium is converted to nitrite and then nitrate This process naturally occurs in the environment, where it is carried out by specialized bacteria
The act or process of oxidizing nitrogen or its compounds so as to form nitrous or nitric acid
