Thanks for the info. Two interesting well written articles about soil and trees are here: Thought you might enjoy them. They are written by a man who was a foremost authority on trees world wide. Or shall I say viewed by many, mostly those who looked through his microscope with him. Many refused.
It would be nice if they went to old growth forest and obtained optimal fertility levels for trees (species specific).
A Touch of Chemistry
Doesn't say what they saw, except it was with x-rays and it was way cool:-(
That was interesting but another page, about how tree ferns can soak up arsenic from contaminated land, was too. I was amused by the statement:
" ... ferns clean up contaminated soil by a process called phytoremediation. A contaminant -- like arsenic -- is absorbed through the plant's roots. The arsenic then moves up to the leaves where it's stored. The leaves can then be cut off. "
And then what? How do you dispose safely of the leaves??

LOL
Yes, I saw that one, but wasn't sure if it would be of interest. After all, how many of us gardeners have arsenic-y land?
But now that the question has been raised, how/why DOES land become contaminated with arsenic? Any chemists around who might know whether it is a by-product of some industrial or milit ary process?
Inquiring minds...

Arsenic is a carcinogen which causes many cancers including skin, lung, and bladder as well as cardiovascular disease.
Where the hell is Arsenic coming from?
Mother Nature. Arsenic comes from the natural world. Arsenic is like copper, iron, boron. It just is. Sometimes, Mother Nature can be a bitch;-)
And I'd still like to know how the fern leaves can be disposed of safely :-)

So would the EPA. At present, a clay lined pit seems to be the only answer. Sequestering arsenic with iron can remove/reduce arsenic from drinking water but the arsenic becomes mobile again with time:-(
I see. :-)
Do you believe this poster? "Arsenic comes from the natural world". Yeah, but how is it used in the "un-natural" world?
Try doing a Web search with keywords like "industry. military and agribusiness uses of arsenic".
Just ONE hit:

Can anyone believe you are just asking about arsenic exposure? You challenge my statement, then you agree with me? I was writing about arsenic in ground water and you want to deprecate my character for that? OK.
If you want to expand the parameters of your search, why don't you include Googling arsenic and flying saucers, my identity challenged little friend? Who are we today, Persephone, Queen of the Underworld and Goddess of Spring, or Aspasia, the brothel keeper and harlot?
ALL RIGHT! Don't forget to hold your breath.
While she is quiet, you might Google
You know it's not really research when you predetermine the outcome and then only use facts that support your position. QED my tuchus.
