To help clarify misconceptions, a general overview of the application of soil EC to precision agriculture is presented.
The value of spatial measurements of soil EC to precision agriculture is widely acknowledged, but soil EC is still often misunderstood and misinterpreted.
As a result, soil EC has become one of the most frequently used measurements to characterize field variability for application to precision agriculture. Brown, Jr., Salinity Laboratory over the past two decades, soil electrical conductivity (EC), measured using electrical resistivity and electromagnetic induction (EM), is among the most useful and easily obtained spatial properties of soil that influences crop productivity. Due in large measure to the prodigious research efforts of Rhoades and his colleagues at the George E.
