Soil electrical conductivity

Measures how readily a soil extract conducts electricity, which indicates the level of dissolved salts.

Plain-language explanation

What the test tells you.

The project specification controls the exact method and acceptance requirement.

A soil paste or extract is prepared at a controlled ratio and tested with a calibrated conductivity meter.

Representative soil, specified liquid, mixing equipment and calibrated conductivity meter.

Electrical conductivity of the extract, normally reported with the required temperature basis.

Used when assessing salinity, chemical conditions and potential interaction with construction materials or buried infrastructure.
