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 9 benchmarks together — the OptimalRange form drives the primary score, while 8 guard(s) constrain the result.
Evidence & Context
An optimal range for this biome under conservation is likely between 1.0 and 2.0.
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 defines the optimal fungal to bacterial biomass ratio range in tropical monsoonal savanna soils under conservation management, indicating good soil health and ecological function.
This encompasses the observed mean of 1.4 and the broader global savanna average of approximately 1.8. This range reflects a system with good soil structure, efficient nutrient cycling, and resilience.
