Soil pH
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.
Evidence & Context
The optimal range for ecosystem health and resilience on volcanic-derived soils is identified as pH 5.5 to 7.0.
Soil pH is a measure of the hydrogen ion concentration (H+) in the soil solution
Optimal pH range for ecosystem health and resilience on volcanic-derived soils.
This range encompasses the benchmark from the high-integrity Mt Gower site and aligns with the 'acid to neutral' characteristics of healthy Ferrosols in the Norfolk Island National Park.
