  Dear Sir:

    I would like to know about the possibility to measure soil electrical
conductivity by TDR. Our instrument ( Soil Moisture Trase System)can
measure EC values up to 4 dS/m. Is there the possibility to measure EC up
to 10-15 dS/m by this technique?. I know literature reports on this
subject( Dalton equation, Zegelin , ...and so on) but I dont know if exists
an instrument operating with the TDR principle capable to measuring
simultaneously soil volumetric water content and bulk electrical
conductivity up to 10-15 dS/m.

    Thank you
