Soil Electrical Conductivity (EC)
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 3 benchmarks together — the MaximumOnly form drives the primary score, while 2 guard(s) constrain the result.

Evidence & Context
Therefore, the proposed reference value for high environmental health is < 0.20 dS/m (measured as EC₁:₅).
Soil Electrical Conductivity (EC) measured as EC₁:₅, indicating the concentration of dissolved ions in soil water.
This benchmark represents the best available soil electrical conductivity condition for high environmental health in agricultural cropping systems within the Temperate Grassy Woodlands & Plains biome.
Derived from state government guidelines (Agriculture Victoria, NSW DPI) and evidence from healthy remnant native woodlands, representing a synthesis of general guidelines rather than direct measurement from multi-site studies.
