Resumen:
This standard specifies a method for determining soil dehydrogenase activity using 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT). It is not applicable to determine the dehydrogenase activity in upper layers (L, Of, Oh horizons) of forest humus forms with low microbial activity (e. g. mor) or in soils showing reducing properties (e. g. waterlogged soils).
