The electrical conductivity (EC) of the soil solution was measured in situ in a soil‐plant system during three irrigation cycles. The salinity sensors used to make the measurements responded to changes in EC resulting from water uptake by the plant and salt movement in the soil profile by convection of salt in soil water. The accuracy of the measurements was estimated to be ± 0.5 mmho/cm throughout the irrigation cycles.
