The Watermark sensor (granular matrix sensor) is an indirect method of measuring soil water. It is an electrical resistance type sensor read by our Moisture Meter. It is also the same exact sensor as the Davis 6440 Soil Moisture Sensor.
This sensor has been the subject of scientific investigation by plant and soil science since the mid-1980's, and has demonstrated itself to be an affordable and practical substitute for tensiometric measurement in most agricultural and landscape irrigation environments.
