Evidence & Context
The resulting benchmark of 0.4 dS/m reflects a condition where soil possesses sufficient soluble nutrients to support healthy plant and microbial life but remains well below levels that would indicate unnatural salt accumulation or pose a salinity risk.
Soil Electrical Conductivity (EC) is a measure of the ability of the soil solution to conduct an electrical current, reflecting the concentration of soluble salts in the soil.
The benchmark is defined as the soil electrical conductivity level representing high environmental health in agricultural systems, balancing nutrient availability and salinity stress.
The benchmark is strongly anchored in real-world field data from an unmanaged ecosystem within the target biome and supported by established soil science principles and crop-specific physiological data from analogous agricultural regions.
