Question

Soil salinity is measured by

• A. Potometer
• B. Porometer
• C. Conductivity meter
• D. Salinator

Answer 1

The correct option is C

Conductivity meter

Water and soil salinity are measured by passing an electric current between the two electrodes of a salinity meter in a sample of soil or water.

Salts increase the ability of a solution to conduct an electrical current, so a high electrical conductivity value indicates a high salinity level.

Electrical conductivity is a term used to describe a measurement unit of salinity.
