Fungal/bacterial ratio
The fungi/bacteria ratio indicates the proportion of fungal biomass in relation to bacterial biomass, and is expressed in mg C / kg. This ratio is calculated by dividing carbon in fungal biomass by carbon in bacterial biomass. In general, undisturbed ecosystems have a higher fungi/bacteria ratio than disturbed systems. Organic and low-input systems have a higher fungi/bacteria ratio compared to enriched conventional systems. Disturbances such as tillage and the removal of crop residues can lower the fungi/bacteria ratio.
