An EM38 is a geophysical surveying instrument made by Geonics Limited in Canada. The EM38 is a popular instrument for EM soil mapping because it is lightweight and easy to use. VRT Solutions has a range of electromagnetic induction (EMI) sensors to cater for each project requirements. VRT Solutions operates a DualEM 1s, DualEM 21s, and Geonics EM38 MKII. Generally the use of these instruments are referred to as EM surveys. Changes in EM readings across a typical paddock can be indicative of changes in salinity, clay percentage, and prescence of moisture and metal or several of these factors at once! In Western Australia, gamma radiometrics is a necessary sensor which provides a complimentary dataset which is collected simultaneously. We use both sensors together due to the high prevalence of low EM soils in WA. In terms of standardising precision agriculture approach, EM38 surveys or DualEM surveys are becoming more commonplace as a starting point. An EM (Electromagnetic) and gamma radiometric soil survey offers a cost effective method to have a higher accuracy in variable rate (VR) applications. This in turn can lead to better cost recovery, and better crop performance.
