DESCRIPTION
BS EN ISO 23753-2:2019+A1:2020
This standard BS EN ISO 23753-2:2019+A1:2020 Soil quality Determination of dehydrogenases activity in soils is classified in these ICS categories:
- 13.080.30 Biological properties of soils
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.
