treat (soil) with nitrates treat with nitrogen or a nitrogen compound convert into nitric acid, nitrous acid, or nitrate, especially with the action of nitrobacteria
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 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 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 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 process whereby ammonia in wastewater is oxidized to nitrite and then to nitrate by bac- terial or chemical reactions Nitrilotriacetic Acid (NTA): A compound now replacing phosphates in detergents
The conversion of nitrogenous matter into Nitrates by bacteria; the process whereby ammonia in wastewater is oxidized to nitrite and then to nitrate by bacterial or chemical reactions ADVANCE \x 540
A process of oxidation, in which nitrogenous vegetable and animal matter in the presence of air, moisture, and some basic substances, as lime or alkali carbonate, is converted into nitrates
