Technical Abstract: Electrical conductivity measurements have been used for years to determine soil salinity and soil moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a non-invasive, non-destructive sampling method. No probes are required using EM, and measurements can be done quickly and inexpensively.
