Soil moisture measured with capacitive sensors like EC5, HS10 or TE5
responds very well on irrigation, rain or water use by plants. Nevertheles it
does not tell if the water is easy available or hardly hold by the soil. Sensors
giving water tension like tensiometers or watermark sensors are showing the
plant availability of the water much better. This sensors are limited to show
the dynamics of the soil water. To use the benefits of both systems Pessl
Instruments have developed a PCB on which we can caonnect 2 watermark
sensors, 2 ECH2O probes and a soil temperature.
