WebSoil electrical conductivity, referred to as EC, is the ability of soil to conduct (transmit) or attenuate electrical current. EC is expressed in milliSiemens per meter (mS/m) or at times is reported in deciSiemens per meter (dS/m). Over the years, soil scientists have used EC to measure soil salinity. However, soil EC measurements also have the potential for … WebThe Electrical conductivity is the inverse of the resistivity and is given by. σ = 1/ρ. Where, σ = electrical conductivity. ρ = resistivity. This ability of conductance in water is directly proportional to the concentration of the …
