Session 1: Electrical properties and signals of soil systems


The study of bulk properties of soils dates to the 1940’s and even before, initially with respect to geological structure and mineral exploration, and more recently to environmental and agricultural reasons. In this session we will explore the current trends in the use of geo-electrical methods in soil and agricultural exploration, starting from electrical resistivity tomography (ERT) of agricultural fields, through induced polarization (IP) methods to explore soil chemical composition, ending with passive electrical signatures such as self-potential (SP) associated with redox reactions in the subsurface. In parallel we will also look at environmental applications of geo-electrical methods.
