Determining Soil Electrical Conductivity‐Depth Relations Using an Inductive Electromagnetic Soil Conductivity Meter

Abstract

Abstract A new inductive electromagnetic device (EM) for measuring soil electrical conductivity (EC a ) was tested. Practical and accurate methods are given for measuring EC a by soil depth intervals through soil profiles using a succession of EM readings made at various heights above ground. In contrast with other devices and methods for field salinity appraisal, readings are obtained without any soil‐to‐instrument contact. The device is well suited for field investigations of soil salinity.
