      abstract     = {To answer long-standing questions about how plants use and
                      regulate water, an affordable, noninvasive way to determine
                      localroot water uptake (RWU) is required. Here, we present a
                      sensor, the soil water profiler (SWaP), which can determine
                      local soilwater content (u) with a precision of 6.10 25 cm 3
                      $ cm 23 , an accuracy of 0.002 cm 3 $ cm 23 , a temporal
                      resolution of 24 min, and aone-dimensional spatial
                      resolution of 1 cm. The sensor comprises two copper sheets,
                      integrated into a sleeve and connected to acoil, which form
                      a resonant circuit. A vector network analyzer, inductively
                      coupled to the resonant circuit, measures theresonance
                      frequency, against which u was calibrated. The sensors were
                      integrated into a positioning system, which measuresu along
                      the depth of cylindrical tubes. When combined with
                      modulating light (4-h period) and resultant modulating
                      planttranspiration, the SWaP enables quantification of the
                      component of RWU distribution that varies proportionally
                      with total plantwater uptake, and distinguishes it from soil
                      water redistribution via soil pores and roots. Additionally,
                      as a young, growingmaize (Zea mays) plant progressively
                      tapped its soil environment dry, we observed clear changes
                      in plant-driven RWU and soilwater redistribution profiles.
                      Our SWaP setup can measure the RWU and redistribution of
                      sandy-soil water content withunprecedented precision. The
                      SWaP is therefore a promising device offering new insights
                      into soil–plant hydrology, withapplications for functional
                      root phenotyping in nonsaline, temperature-controlled
                      conditions, at low cost.},
