Electrical Conductivity

Description

EC (in 1:2 soil:water).

This is a soil salinity test. This method quantifies the amount of dissolved salts by measurement of the electrical conductivity of a soil saturated paste extract. The relationship between electrical conductivity and soluble salts is approximate due to differences in equivalent weights, ion equivalent conductivities, and relative proportions of major solutes in the paste extracts. Salt tolerance crop data is generally expressed in terms of the electrical conductivity of the saturation paste extract and used to assess the potential of soluble soil salts which may limit crop productivity. The method detection limit is approximately 0.01 dS/m (mmhos/cm) and is generally reproducible within ± 7%.
