| Note in Official Journal: | |
| Subject of the standard: | 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. |
