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 the acidity or alkalinity of the soil solution.
A benchmark range of soil pH representing high environmental health under sustainable agricultural management in tropical monsoonal savannas.
The benchmark is supported by recent research at Katherine Research Station and aligns with soil health indicators such as Cation Exchange Capacity (CEC), critical for nutrient retention and ecosystem resilience.
