This invention presents a methodology for determining the magnetic characteristics of soils and their interrelationship with the dielectric response of the soil mass involves testing various soils using a magnetometer. These soils, with different characteristics, are analyzed for their magnetic properties and correlated with their physical, chemical, mineralogical, and electrical properties using an impedance analyzer. This approach provides a quick, non-invasive method to measure soil-specific parameters, establishing the influence of magnetic properties on the dielectric response. This methodology facilitates in-situ measurements, crucial for addressing geo-environmental challenges effectively.

A methodology for determining the magnetic characteristics of soils and their inter-relationship of magnetic characteristics with the dielectric response of the soil mass, characterized by the following steps.
- placing 20 mg of air-dried soil sample in a pick-up coil;
- subjecting the said soil sample between the poles of an oscillating electromagnet that creates a uniform magnetic field;
- calibrating the magnetometer at 27 °C by using Palladium to obtain the magnetic characteristics of the soil;
- wherein the mineralogical composition of the soil sample is determined by using an X-ray diffraction spectrometer, wherein the fraction percentage by weight of the mineralogical composition is determined using Rietveld analysis by using the X'Pert High Score Plus software with PDF-4+ database
