Scope

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 O 2 , the method is more robust than the TTC-method described in ISO 23753‑1.
