This part of ISO 14240 specifies a method for the estimation of
microbial biomass of soils by measurement of total extractable
organic biomass material mainly from freshly killed microorganisms.
The method is also applicable to the estimation of microbial
nitrogen and microbial ninhydrin-reactive nitrogen in soil, but
this part of ISO 14240 describes only the measurement of
extractable organic carbon. The fumigation-extractio
NOTE Chloroform fumigation also affects soil fauna. The contribution of carbon from these organisms is generally small (< 5 %) and can usually be neglected.
