I´am mesuring ground conductivity over almost 1 year regularly
today it was 15,6 Ohm / m ( measured with 16Volt@ 50Hz )
I try to built a measuring device with other frequency , somthing odd
( no multibles from 50Hz, thinking about 111 Hz - ) and automatic
daily measurements ( at present times done manually)
Would like to discuss about it

Although it is interesting to know the ground conductivity, the main
losses in a small LF antenna are environmental. This includes losses
in trees, buildings etc. These are sometimes all lumped together and
misleadingly described as 'ground losses'.
A more useful thing to measure would be the total environmental loss
which varies with the seasons (my antenna needs much more inductance
when the leaves fall off the trees) and weather effects such as rain
and frozen soil.
