ahahaha... ahahahaha... Hey, yo!.. Farooq!.... ahahahaha...
That is some kind of super Oak you've burnt there... along
with some high class Ph.D. chemist doing his over-unit analysis:
%
Sr 533.6
Ba 3560.3
Pb 46.1
Zn 2112.4
Eating this ash ought to be good for prostate problems (Zn)
.... and great for/as an X-ray contrast medium (Ba & Sr).
The Lead (Pb) might be a problem, however there appears
to be sufficient P2O5 and SiO2 present to from very, very
insoluble Pb-products. Still the enviro shits will declare this
to a be a very toxic and hazardous substance... while levying
and assessing you with permit charges, user fees and enviro
surtaxes... even if you never make or sell any of this miraculous
ash... and then the tree huggers will sue you for having burnt
such a valuable and endangered plant which has sucked up and
decontaminated so more than its possible share of toxic
substances from the environment thru'/via its bio remediation....
ahahahahaha.. Thanks for the laughs, Farooq.... ahahahaha.....
ahahaha... ahahahanson

Soil and Dirt particles?! Is that a scientific analysis? Contaminated?
Do you see many pure celulose trees?

Ideally, you should get CO2 and H2O, but nothing's ideal. You don't get
enough Oxygen to get such efficient burning, so, you get a lot of
charcoal (near pure carbon), as well as lots of other stuff like
nitrates and salts that are absorbed from the soil.
You could look at some analytical techniques ot detect levels of such
nitrates and salts, which should be fairly straight forward, but I'm a
chemoinformatician not an analyst....
We know this because ash used to be the main source of nitrates

I strongly doubt that. Nitrates would not survive high temperatues (of
burning wood) especially in the presence of organic matter. Wood
ash is indeed rich in what we call as pot-ash and hence the name
potassium.
