WebSoil electrical conductivity (EC) measures the ability of soil water to carry electrical current. Electrical conductivity is an electrolytic process that takes place principally through water-filled pores. Cations (Ca 2+, Mg 2+, K +, Na +, and NH 4+) and anions (SO 4 2-, Cl-, NO 3-, and HCO 3-) from salts dissolved in soil water carry ... WebEC Measurement in Soil. Electrical conductivity (EC) is the ability of a material to transmit (conduct) an electrical current and is commonly expressed in units of milliSiemens per meter (mS/m). Soil EC measurements may also be reported in units of deciSiemens per meter (dS/m), which is equal to the reading in mS/m divided by 100.
