A Reconstructed biomass per cell for pinto bean plant PB_5. The black outline marks the rooting area of the plant, black dots denote the electrode positions. B Reconstructed root biomass for each root zone (\(M_{\text {bio, rec}}\)), compared to the validation root biomass estimated by scanning (\(M_{\text {bio, val}}\)). The three different root zone depths within the rhizotron (in cm) are displayed in shades of red, the perfect match of reconstructed and validation biomass is indicated as a dashed grey line
