Evidence & Context
Therefore, the upper detrimental threshold from an ecological standpoint is reached when ECₑ > 2.0 dS/m.
Soil Electrical Conductivity (EC) measured as ECₑ, the electrical conductivity of the saturated paste extract, indicating salinity stress level.
This benchmark marks the upper detrimental threshold for soil electrical conductivity beyond which salinity stress negatively impacts sensitive plants and soil microbial functions in agricultural cropping systems.
Based on ecological data showing negative impacts on microbial processes and sensitive species above this ECₑ level.
