Apparent soil electrical conductivity (ECa) is the most frequently used proximal soil sensing measurement used to delineate relatively homogeneous areas of an agricultural landscape. Since ECa changes in response to a number of influential soil properties, direct use of such measurements has been limited. Changes of soil with depth (layering) have been viewed as a key pedological phenomenon that affects surface-based ECa measurements. The proposed continuous ECa scanner was developed to allow implementing conventional galvanic contact soil resistivity measurement technique to gather information on soil depth with greater details than a series of fixed distance electrodes commonly used in practice.
