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 F:B ratio range for sustainable livestock grazing in Australian Arid Karstic Woodlands & Shrublands is proposed as 0.12 to 0.20.
Fungal:Bacterial ratio measured by PLFA analysis representing the relative biomass of fungi to bacteria in soil.
The optimal range of the Fungal:Bacterial ratio balancing fungal-driven soil building and bacterial-driven nutrient cycling for sustainable livestock grazing in Australian arid karstic woodlands and shrublands.
This range balances long-term carbon sequestration with sufficient nutrient availability for pasture productivity.
