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 17 benchmarks together — the OptimalRange form drives the primary score, while 16 guard(s) constrain the result.

Evidence & Context
A soil with an EC₁:₅ < 0.05 dS/m can be considered critically low, indicating an extremely low ionic strength that may compromise essential biological processes.
Soil Electrical Conductivity (EC) measured as EC₁:₅, indicating the concentration of dissolved ions in soil water.
This benchmark defines the lower critical threshold for soil electrical conductivity below which nutrient depletion and compromised biological function may occur in agricultural cropping systems.
Interpreted from the 'Very low' classification and literature indicating functional depletion below this level.
