Soil quality - Determination of potential nitrification and inhibition of nitrification - Rapid test by ammonium oxidation

ISO 15685:2012 specifies a rapid method for the determination of the potential rate of ammonium oxidation and inhibition of nitrification in soils. This method is suitable for all soils containing a population of nitrifying microorganisms. It can be used as a rapid screening test for monitoring soil quality and quality of wastes, and is suitable for testing the effects of cultivation methods, chemical substances [except volatiles i.e. H > 1 (Henry's constant)], extracts of biosolids and pollution in soils.
