Electrical Conductivity (EC) Meter

An Electrical Conductivity Meter or EC Meter measures the amount of electrical conductivity in your soil. EC can be indicator of the health of your microbial life in your soil. It can also help to indicate the presence of high salts.

Planting (Soil Temps 40° F - 60° F)

SOIL TYPE EC (ERGS) EC (mS)
