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 24 benchmarks together — the OptimalRange form drives the primary score, while 23 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
The widely accepted scientific threshold at which salinity begins to negatively affect sensitive crops and associated ecological processes is an ECe of 2.0 dS/m.
Soil Electrical Conductivity (EC) upper detrimental threshold indicating onset of salinity stress
This benchmark represents the upper detrimental soil electrical conductivity threshold above which salinity stress impairs ecosystem function in arid cropping systems.
Based on well-established principles of plant physiology, microbiology, and soil science indicating salinity stress onset.
