Fungal:Bacterial Ratio
Benchmark Value
Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.
Evidence & Context
An F:B ratio < 0.1 indicates a critically degraded, dysfunctional state prone to nutrient loss and dominated by early-successional weeds.
Fungal:Bacterial Ratio indicating the lower critical threshold below which soil function is impaired.
This benchmark defines the lower critical threshold of the fungal to bacterial ratio below which soil health is severely degraded, leading to nutrient loss and dominance by early-successional weeds in the Arid Inland Floodplains biome under agricultural crop production.
Based on literature characterizing microbial conditions associated with degraded soils and early-successional weed dominance.
