Here I provide the materials to give you an overview of EMI methods and their applications in agriculture, specifically for characteriing soil salinity as electrical conductivity (EC). We also provide a comprehensive guide to the Electromagnetic Sampling Analysis and Prediction Model (ESAP) developed by the USDA.
