Predicting Bulk Soil Electrical Conductivity versus Saturation Paste Extract Electrical Conductivity Calibrations from Soil Properties

Soil electrical conductivity was calibrated with salinity for 12 soil types, and the calibrations were related to soil properties. The calibration slope was found to be highly correlated with water‐holding capacity and saturation percentage, whereas the intercept was highly correlated with clay content. These findings permit the prediction of calibrations for salinity diagnosis applications where direct calibrations are unavailable or unwarranted.
