In the following paper some of the results of this research (US05C) are shown. In addition, some of the future work (US22C) that is planned including the construction of a vehicle that is capable of carrying several EM instruments and a GPS is briefly outlined. The need for developing such a rig is that researchers and extension personnel will be able to assess the current and potential salinity threat more efficiently, in particular in areas where little soil information exists or where incipient traces of soil salinity become apparent in the cotton growing areas. Where salinity does occur, the instruments should provide useful information that will assist in determining the cause, location and extent of the problem. With such data, suitable management strategies to remediate the problem or minimise its spread can be suggested, implemented and subsequently monitored.
