Soil quality. Determination of soil microbial biomass - Substrate-induced respiration method has-hardcopy b) the abstract test method1 Scope This part of ISO 14240 specifies a method for estimating the active aerobic, heterotrophic microbial biomass in aerated agricultural and mineral soils. Determination of the effects of chemicals on biomass is outside the scope of this part of ISO 14240.
