Eman Elsheikh

you can use he gravimetric method to calibrate this probe by taking soil samples for the same depth in the same time with reading of the Probe

Wenceslau Geraldes Teixeira

Gravimetric is the standard method. Only take care to collect soil sample in a similar volume and position that you profile are estimating the soil water.

Imed Ben Aissa

You can calibrate it with gravimetric method or with Teta-probe or ajusted TDR equipment.

Madhav Dhakal

By using gravimetric method of soil moisture measurement. You can use Giddings machine to take 1 m deep cores to get the numbers corresponding to the sensor depths and calibrate the respective ones.

see my profile to get the publication related to the calibration.
