How do they measure that kind of conductivity in mS?, is it the same
method as when you measure soils for safety (mains), or lightning
discharge ground?.

1 skin depth t 1.8 MHz in 8 mS/m soil is ~4 meters

A quick question for the collective wisdom on this esteemed reflector:
How would one categorize the quality of ground consisting of grass. For
example, if you live next to a large (many acres) open space made entirely
of well watered grass, would that qualify as “average ground“, “above
average ground” or something else?
Haven’t been able to find the answer anywhere.
Thanks for your input, as always!
