Applications of Electromagnetic Induction and Electrical Resistivity Tomography for Digital Monitoring and Assessment of the Soil: A Case Study of Al-Ahsa Oasis, Saudi Arabia

Modern geophysical techniques, including electromagnetic induction and electrical resistivity tomography, reveal significant variations in soil salinity and texture at Al-Ahsa Oasis, Saudi Arabia. These findings highlight the impact of factors such as soil type, moisture content, and sabkha on agricultural productivity, offering critical insights for sustainable farming practices. The study utilized ten 2-D electrical tomography profiles and twenty electromagnetic conductivity measurements across 12,000 hectares of cultivated land, identifying distinct geoelectric units that reflect diverse hydrogeological conditions. This research provides actionable data for farmers, development sectors, and research institutions to address groundwater depletion and soil salinity issues, ensuring the long-term sustainability of this historic oasis.
