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 10 benchmarks together — the OptimalRange form drives the primary score, while 9 guard(s) constrain the result.
Evidence & Context
Based on an analysis of available literature pertaining to well-managed agricultural systems within the Australian Tropical Monsoonal Savannas, a benchmark range of pH (0.01M CaCl₂) 6.0 to 6.6 is proposed.
Soil pH measured in 0.01M CaCl₂ solution, indicating soil acidity or alkalinity relevant to soil health and crop production.
Soil pH measured in 0.01M CaCl₂ solution, representing a benchmark range for high environmental health in agricultural systems of the Tropical Monsoonal Savannas biome.
This range is considered representative of the 'best-on-offer' condition, reflecting high environmental health achievable under agricultural research conditions that explicitly incorporate sustainability and soil health objectives.
