EM soil maps provide a useful layer of data to identify and map field variablity of the sub-surface soil to gain a greater understanding of production results and improve accuracy of zone maps.
EM surveying works by emitting an electro-magnetic field into the soil. The strength of this magnetic field and how far it can travel through the soil profile is determined by the textural composition of the soil. This can then be linked to different soil characteristics such as stone and clay content for zoning differing management zones.
In addition to its ability to identify variations in soil texture, electrical conductivity has proven to relate closely to other soil properties that often determine a field’s productivity:
