An electrostatic free-space system acting as a parallel plate capacitor was designed and tested to estimate water content and biomass in situ using greenhouse grown spinach. The attenuation of the transmitted signal through the system was strongly correlated with water content and dry biomass (r 2 = 0.95) using 30.5 cm square plate antennae. The response to objects outside the designed sensing area was minimal.
