Fungal:Bacterial Ratio
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 2 benchmarks together — the MinimumOnly form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context
F:B ratios persistently below 1.0... could indicate compromised soil health, reduced carbon sequestration potential, and a shift away from mature, stable conditions.
The ratio of fungal to bacterial biomass (F:B ratio) in soils is increasingly recognized as a critical bioindicator, offering insights into soil ecological status, functional pathways, and overall health.
This benchmark marks the lower critical threshold of fungal to bacterial biomass ratio below which soil health may be compromised in tropical monsoonal savanna conservation areas.
Persistently low F:B ratios, indicating strong bacterial dominance, are typically associated with intensively managed or disturbed environments.
