Electromagnetic Induction - Ground Conductivity Meters

Mike Catalano, Senior Technical Associate with Geonics Ltd., presents a webinar focused on electromagnetic induction (EMI). Mike reviews basic electromagnetic induction theory and discuss why Ground Conductivity Meters (GCM’s) sensors provide a convenient and low-cost method for measuring variability within soils by simultaneously mapping electrical conductivity & magnetic susceptibility. GCM’s provide a non-invasive, non-destructive sampling method which requires no soil contact. In particular, examples covered will include soil moisture/water content, texture changes, salinity, organic matter, claypan soils, optimizing nitrogen (N) rates and topography. Mapping ground conductivity as a proxy for all these various factors can ultimately be used as a quick and efficient guide to generating management zones, yield mapping and overall increasing the productivity and health for agricultural lands. He also speaks to the latest technological advances in EM sensors.
