ABSTRACT:
There is provided a sensor for measuring a quantity, such as the salinity, of the soil solution without requiring continuous calibration. The sensor is based on a porous material which automatically fills up and saturates when the soil is rewet and drains when the soil dries out from plant uptake or from air drying, then being filled up with a solution representative of the quantity to be measured in the soil during plant growth.
