Soil quality - Determination of dehydrogenase activity in soils - Part 1: Method using triphenyltetrazolium chloride (TTC) (ISO 23753-1:2005);English version of DIN ISO 23753-1:2006-04
This part of ISO 23753 specifies a method for determining the dehydrogenase activity in soil using
2,3,5-triphenyltetrazolium chloride (TTC).
It is not applicable for determining the dehydrogenase activity in the upper layers (L, F, H horizons) of forest
humus forms with Iow microbial activity (e.g. mor), or in soils showing reducing properties (e.g. waterlogged
soils).
