ABSTRACT:
In a method and device for determining the moisture content and conductivity in the ground and in bulk materials, a capacitive sensor is disposed in the ground or the bulk material, the sensor is charged from a constant external voltage supply with a given initial current from a given first voltage threshold value to a given second voltage threshold value and either a voltage/time diagram is determined or a first charging time required for charging the sensor from the first to the second voltage threshold values by the constant external voltage supply is determined and a second charging time is determined wherein either the initial current and/or at least one of the two voltage threshold values are altered and the water content and the conductivity are determined by verification of the two charging times or of the voltage/time diagram.
