Abstract
A sensor for determining soil properties is disclosed herein. The sensor includes a ground engaging structure adapted for coupling to an agricultural implement and to penetrate soil at a predetermined depth. An electrode assembly is disposed on a sensing surface of the ground engaging structure that includes a plurality of electrode sensing units. The plurality of electrode sensing units are configured to selectively generate a series of electric fields that project outwardly into the surrounding soil in response to receipt of an excitation signal and sense changes in the electric field corresponding to a change in a measured electrical output signal that is used to determine one or more soil properties during movement of the agricultural implement in a field.
