Standard NBN EN ISO 17155:2020
Soil quality - Determination of abundance and activity of soil microflora using respiration curves (ISO 17155:2012)
13.080.30 Biological properties of soils
1 Scope This International Standard specifies a test method for determining the activity of active aerobic, heterotrophic microbial biomass in soils. This method is applicable to the monitoring of soil quality and to the evaluation of the ecotoxic potential of soils and soil materials. It is also applicable for soils sampled along contamination gradients in the field and to soils that are contaminated experimentally in the field or in the laboratory.
