Based on the assumption that diffusion of solutes into and out of the sensitive element of a salinity sensor determines its response time, a theory was developed to describe the response of the sensor to changes in soil salinity. This theory was experimentally verified in solution and in soils. The response of a sensor was shown to be adequately described by a single response factor. Proper use of this factor permits the actual electrical conductivity of the soil solution to be inferred from sensor readings where soil salinity changes rapidly.
