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 4 benchmarks together — the OptimalRange form drives the primary score, while 3 guard(s) constrain the result.

Evidence & Context
The mean F:B ratio across all fire treatments (unburnt, early biennial, late biennial) was 1.4±0.41 (S.D.)
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 represents the typical fungal to bacterial biomass ratio in soils of tropical monsoonal savannas under minimal recent disturbance, reflecting a healthy soil microbial community in conservation areas.
The 'unburnt' plots provide a proxy for minimal recent disturbance. The resilience of the F:B ratio to different fire frequencies and timings suggests that this value may be representative of well-managed conservation areas.
