A low cost dielectric spectroscopy instrument dedicated to in-situ soil permittivity profile mapping

Monitoring properties of soil from microwave remote sensing is a very effective tool. In this context, the knowledge of soil permittivity values is important in order to guarantee the accuracy of the monitoring. Previous studies have showed the impact of temperature and moisture gradients in the top soil layer permittivity profile on remote sensing monitoring of soil. To increase our knowledge of these phenomena, we developed a new low cost equipment for continuous in-situ measurements of microwave [100 MHz-3GHz] permittivity soil profiles.
