EN ISO 23753-1:2011

Soil Quality - Determination of dehydrogenase activity in soil - Part 1: Method using triphenyltetrazolium chloride (TTC) (ISO 23753-1:2005)

ISO 23753-1:2005 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 low microbial activity (e.g. mor), or in soils showing reducing properties (e.g. waterlogged soils).

Bodenbeschaffenheit - Bestimmung der Dehydrogenaseaktivität in Böden - Teil 1: Verfahren mit Triphenyltetrazoliumchlorid (TTC) (ISO 23753-1:2005)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Dehydrogenaseaktivität von Böden mit 2,3,5-Triphenyltetrazoliumchlorid (TTC) fest.
Sie gilt nicht für die Bestimmung der Dehydrogenaseaktivität in Auflagehorizonten (L, F, H) von Wald-humusformen mit geringer mikrobieller Aktivität (z. B. Moor) oder in Böden mit reduzierenden Eigenschaften (z. B. staunasse Böden).

Qualité du sol - Détermination de l'activité des déshydrogénases dans les sols - Partie 1: Méthode au chlorure de triphényltétrazolium (CTT) (ISO 23753-1:2005)

L'ISO 23753‑1:2005 spécifie une méthode de détermination de l'activité des déshydrogénases dans le sol à l'aide de chlorure de 2,3,5‑triphényltétrazolium (CTT). Elle ne s'applique pas à la détermination de l'activité des déshydrogénases dans les couches supérieures (horizons L, F et H) des formes d'humus de forêt à faible activité microbienne (par exemple le mor), ou dans les sols présentant des propriétés réductrices (par exemple les sols saturés d'eau).

Kakovost tal - Določevanje aktivnosti dehidrogenaze v tleh - 1. del: Metoda s trifeniltetrazolijevim kloridom (TTC) (ISO 23753-1:2005)

ISO 23753-1:2005 opredeljuje metodo za določevanje aktivnosti dehidrogenaze v tleh z uporabo 2,3,5-trifeniltetrazolijevega klorida (TTC). Ne velja za določevanje aktivnosti dehidrogenaze v zgornjih plasteh (horizontih L, F, H) gozdnih oblik humusa z nizko mikrobno aktivnostjo (npr. trhlini) ali v tleh z redukcijskimi lastnostmi (tleh, prepojenih z vodo).
