ABSTRACT:
A soil electrode assembly supports an electrode member disposed in soil in front of another electrode member so that a resistivity of a volume of the soil that is between the electrode members is measured by energizing and monitoring the electrode members. The soil electrode assembly includes a substantially flat support member having two principal opposite faces and a lower end drivable into the soil. The support member is made of rigid material. One of the faces of the support member includes a first opening providing an access to a first compartment. The soil electrode assembly also includes a substantially flat insulating member having two principal opposite faces. The insulating member is mounted in the first compartment. One of the faces of the insulating member includes a second opening providing an access to a second compartment. An electrode member is mounted in the second compartment.
