Obtaining Chemical Properties through Soil Electrical Resistivity

open access: yesJournal of Civil Engineering Research, 2012
The electrical resistivity of soil is significantly influenced by shape of the particle of soil, presence of mo isture in soil, chemical properties of soil and presence of organic materials in soil. Chemical p roperties of soil such as Soil pH, Cation exchange capacity (CEC), soil salinity can be efficiently determined by electrical resistivity of soil.
