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 4 benchmarks together — the MaximumOnly form drives the primary score, while 3 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
A soil with an ECe of less than 1.0 dS/m would be in equilibrium with low-salinity floodwaters, would be well within the international "non-saline" classification, and would be low enough to pose no osmotic stress to the full suite of native floodplain vegetation.
Soil Electrical Conductivity (ECe) in the topsoil (0-30 cm) of cracking clay soils
This benchmark represents the maximum soil electrical conductivity in the topsoil of cracking clay soils that indicates a non-saline state where secondary salinisation is not occurring and the hydrological cycle remains intact in the arid inland floodplains.
This value is derived from a weight-of-evidence synthesis including the MDBA water quality guideline and USDA soil classification, representing a 'non-saline' soil state in equilibrium with low salinity floodwaters.
