3.1 Resistivity
Resistivity (or conductivity) measures the voltage
potential gradient through a soil matrix when an
electrical current is applied across a soil specimen. It
has been applied to detect variations in soil density,
displacements and deformations within soil [17], soil
compression, altering of pore fluid composition [18],
biological activity [19], and extent of soil improvement
i.e. the migration of contaminant/chemical plumes, and
the progress of passive bio-remediation methods [20].
However, this technique was found in biocementation
(biocalcification) monitoring minimally due to the
changes of many factors (Table 2) influencing soil
resistivity making the difficulty to clarify the benefits
actually realized in the soil matrix [2].
