«This happens because the presence of microbial cheaters ultimately reduces the total amount of enzymes produced by the microbial community, while the total amount of microbial biomass stays about the same» explains University of Vienna ecologist and IIASA guest researcher Christina Kaiser, who led the study.

No - till systems had greater soil microbial biomass and enzymatic activity. (sciencedaily.com)
In contrast to other tillage equipment, such as moldboard plows or disc plows, the use of chisel plows was associated with greater microbial biomass. (sciencedaily.com)
