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. The scoring engine uses 2 benchmarks together — the OptimalRange form drives the primary score, while 1 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
The recommended reference value for best available condition is a topsoil pH range of 5.0–6.5 (measured in 0.01M CaCl2).
Topsoil pH measured in 0.01M calcium chloride (CaCl2) solution, representing soil acidity/alkalinity affecting nutrient availability and ecosystem health.
Soil pH measured in 0.01M CaCl2 solution indicating the acidity or alkalinity of topsoil affecting nutrient availability and forest health.
Derived from synthesis of scientific literature and expert horticultural guides identifying ideal conditions for nutrient availability and vigorous tree growth in Eucalyptus-based production forestry.
