适用范围：This part of ISO 23753 specifies a method for determining soil dehydrogenase activity using2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT). As the INT reduction is less sensitive toO2, the method is more reproducible than the TTC-method described in ISO 23753-1.It is not applicable for determining the dehydrogenase activity in upper layers (L, F, H horizons) of foresthumus forms with low microbial activity (e.g. mor), or in soils showing reducing properties (e.g. waterloggedsoils).
