Water vs. soil readings on your EC meter

Although there is no substitute for the precise salinity evaluations that you can get from saturated paste extract data from an analytical lab, we highly recommend the use of an electrical conductivity (EC) meter for rough estimates. But there is one very important mistake that is sometimes made when using this meter. And that is forgetting that there is big difference between measuring soil salinity and water salinity.

The EC meter works by measuring electrical current (the movement of electrons)…
