Description
The tensiometer is a relatively inexpensive instrument capable of measuring the force or suction which a plant root must overcome to extract moisture from the soil. It is a sensitive “mechanical root” that indicates, without prior calibration, the availability of water in the root zone. It does not measure the quantity of water directly.
