Soil quality Determination of dehydrogenases activity in soils. Method using iodotetrazolium chloride (INT) | Status: Current

1 Scope This document specifies a method for determining activity of dehydrogenases in soil, using 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT)[1]-[5]. As the INT reduction is less sensitive to O2, the method is more robust than the TTC-method described in ISO 23753‑1.
