You are in farm country where the annual rainfall is 835mm. Where the
mean temperature is 12.8°C. Where the soil is 20% sand, 65% silt, and
15% clay.

What is the Conductivity in the 80M band?

Answer: 30 mS

====================================

I don't know. And neither do you or anybody else.

Such answers above have been know for decades.

If you DID know you would not have the foggiest idea what to do with
the data anyway. I might!

You might? With emphasis too. Now if that isn't a firm declaration
to end the pursuit in "How to measure soil constants at HF." In
point of fact, you simply validate my premise:

Let's draw a chord between 3 soil samples to see how fruitless knowing
"How to measure soil constants at HF" really is

As you struggled on:
There's missing data. You forgot the iron oxide content and soil permeability.
There is so much missing information as: What is it to an average of
one skin depth in YOUR garden, old son?

To this point all method and no results. By contrast, Walt provided
both, and his data shows a continuity to your pronouncement about the
wavelength shortening of radials adjacent to the ground - something
you proclaimed no antenna measurement could achieve.

Walt's method necessarily includes one skin depth (and more) that your
scraping at the veneer of soil could never model. He doesn't have to
worry about temperature, moisture, time of day, season, iron oxide
content, or permeability - it comes free with the attempt and you
don't have to haul mud into the kitchen. Do I hear John Cleese
muttering something about the Bloody Obvious?
