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
Based on the synthesis of evidence presented in Table 1, the F:B ratio of 0.20 is proposed as the benchmark for the best available condition.
Fungal:Bacterial ratio measured by PLFA analysis representing the relative biomass of fungi to bacteria in soil.
The Fungal:Bacterial ratio measures the balance of fungi to bacteria in soil microbial communities, indicating ecological health in Australian arid karstic woodlands and shrublands under livestock grazing.
It originates from a real-world, high-functioning ecological state within the target Australian arid biome and is associated with higher soil carbon, nitrogen, and microbial activity.
