                      a function of soil water isconsidered an important
                      information for the study of root physiology. A non-invasive
                      tool based onelectromagnetic wave transmittance in the
                      microwave frequency range, operating close to 4.8 GHz,was
                      developed using microstrip patch antennas to determine the
                      volumetric moisture of soil inrhizoboxes. Antennas were
                      placed on both sides of the rhizobox and, using a vector
                      networkanalyzer, measured the S parameters. The dispersion
                      parameter S<sub>21</sub> (dB) was also used to show
                      theeffect of different soil types and temperature on the
                      measurement. In addition, system sensitivity,reproducibility
                      and repeatability were evaluated. The quantitative results
                      of the soil moisture,measured in rhizoboxes, presented in
                      this paper, demonstrate that the microwave technique
                      usingmicrostrip patch antennas is a reliable, non-invasive
                      and accurate system, and has shown potentiallypromising
