Use of Electrical Geophysical Methods for Supporting Agricultural Practices

摘要

Geophysical methods have been increasingly popular for shallow and environmental studies worldwide. In particular an electrical geophysical method is helpful in soil investigation which focuses on an interval from the ground surface down to a depth of 2 meters. The instrument of electrical geophysics were developed and successfully applied to assist in precision agricultural practices worldwide, i.e. Europe, Russia, and US. Our group from Indonesia has modified a resistivity instrument that integrates with other components and could increase mobility in soil mapping. The instrument measures electrical resistivity, conductivity, and potential that can be used for agricultural applications. In addition, we created forward modelsto help us understand and detect limits of our target.
