A system for monitoring soil conditions within a field includes an agricultural implement including a frame and a ganged tool assembly supported relative to the frame and including a toolbar coupled to the frame and a plurality of ground-engaging tools coupled to the toolbar. The system further includes a first sensor provided in operative association with the ganged tool assembly and configured to detect motion of the ganged tool assembly. The system further includes a second sensor separate from the first sensor configured to detect an orientation of the ganged tool assembly relative to at least one of the field or the frame. The system includes a controller communicatively coupled to the sensors and configured to determine an indication of a soil condition at a given location within the field based at least in part on the detected motion and orientation of the ganged tool assembly.
