New article in Sensors journal

On November 22nd we published a new article in Sensors (, where we explored the dielectric properties of soil at different electromagnetic frequencies. The bandwidth analysed ranges from 1MHz to 6 GHz and the materials studied are mainly clays and clay soils with different mineralogical compositions. This study proposes a new mixing model that tries to explain the dielectric dispersion caused, among others, by the Maxwell-Wagner effect and shows the importance of taking into account the measurement frequency when interpreting the accuracy and detecting the deficiencies of the dielectric soil moisture sensors. Furthermore, one of the main characteristics of this publication is the proposal of a new paradigm to differentiate between the possible states of water confinement in the soil.
This publication, in which we have prestigious international researchers in soil science, from important research centres such as the UK Centre for Ecology and Hydrology, the Volcani Center in Israel or Utah State University, is the result of a research stay by our predoctoral FPU member Juan Domingo González Teruel and Professor Pencho Soto, which took place last year with Doctors David A. Robinson and Inmaculada Lebron in the Welsh city of Bangor.

Start of the IRRIFRUT project

Good news! We are starting a new and exciting journey with the IRRIFRUT project which is funded by the State Research Agency (AEI) with the code PID2019-106226RB-C2/AEI/10.13039/501100011033, and it is the natural continuation of the former ARIFRUT project.
The IRRIFRUT project (Automation of precise irrigation of fruit trees based on soil and plant water sensors)  will be developed over the next three years in coordination with CEBAS. In our part, we will carry out the design and evaluation of sensors and methodologies to obtain indicators of crop water stress and the automatic management of deficit irrigation.

SEIA’2018 Conference

From the 19th to 21st of September was held in Ámsterdam the Fourth International Conference on Sensors and Electronic Instrumentation Advances (SEIA’ 2018). Our PhD student, Juan Domingo González, presented the contribution “Design and simulation of a soil sensor using microstrip lines and neural networks”  in the Environment Sensors session.
