Microbial biomass carbon measures the amount of soil organic carbon present in living bacteria and fungi by nutrient testing in the lab. Biologically healthy soil contains about 3-5% of the total organic carbon contained in soil microbes. This test needs to be done in conjunction with a measurement of soil organic carbon on the same soil sample.
