| Abstract: | The results of field and in-door experiments and comparison with Neutron Probe showed that the 6050X1 Time-Domain Refleetometry (TDR) had high preeision and speed in measuring soil water content,also the longer the wave guides is,the
bigger the variation error in the results measured with TDR.This paperpresents five adiusting formulas for the length selcetion of water guides. |

| Keywords: | Time-Domain Reflectometry soil water content measuring precision neutron probe |
