Electrical Geophysical Methods in Agriculture

Mapping alluvial soils of humid areas with electrical geophysical methods.

  We tested the electrical geophysical methods of non-contact electrical profiling (NEP) and electrical profiling (EP) for mapping peat and mineral alluvial soils formed in the glacial valley of Yachroma river. More >>

Vertical Electrical Sounding to detect groundwater levels in arid areas

The approximate location of the groundwater table was estimated by a visual inspection of the VES curve. The AB/2 value with the sharp change to the low resistivity (3-20 ohm m) was selected from each VES profile...More >>

Application of the geophysical methods of electrical resistivity in precision farming 

 One of the challenges facing the adoption of precision agriculture technology is the identification of productivity-related variability of soil properties accurately and cost-effectively. More >>

Evaluation of stone contents in soils with electrical geophysical methods to aid orchard planning

Geophysical methods of electrical resistivity, such as VES and four-electrode profiling provided the information about spatial distributions of stones in skeletal soils.  High resistivity will indicate the presence of stones in soil profiles. More >>

LandMapper ERM-02  was demonstrated at 2008 Joint Annual Meetings of GSA-SSSA-ASA-CSSA . Next FIELD DEMO will be during 22^nd SAGEEP (Symposium on Applications of Geophysics to Engineering and Environmental Problems), March 29-April 2, 2009 at Fort Worth, TX. See News.
