Thorough knowledge of root system functioning is essential to understand the feedback
loops between plants, soil, and climate. In situ characterization of root systems is …

This paper provides an update on the fast‐evolving field of the induced polarization method
applied to biogeophysics. It emphasizes recent advances in the understanding of the …

Bioretention cells, or rain gardens, can effectively reduce many contaminants in polluted
stormwater through phytoremediation and bioremediation. The vegetated soil structure …

Geoelectrical methods are increasingly used to investigate soil‐plant interactions in an
agricultural context. For this, it is essential to quantify root electrical properties, since they …

Electrical impedance spectroscopy has long been considered a promising technique for
noninvasive, in‐situ root investigation because of its sensitivity to anatomy and physiology …

Core Ideas The impact of roots on bulk electrical conductivity was studied using a modeling
approach. The presence of roots affects petrophysical relations. The effect of roots is more …

Measuring root properties, the “hidden half” of the plant, is challenging due to their
heterogeneous and dynamic nature. A promising method for noninvasive mapping of roots …
