down the rabbit hole half way

Because I want to look at the dirt.

You look up the composition of dirt and you can get how much of it is inorganic, and some of what elements may be present, but it's very hard to find stuff on percentages of element in soils. Obviously this will vary a lot -- I found stuff on the dangers of too much aluminum for plants -- but literally nothing on percentages.

Fortunately, gemstones are easier because I need their composition, too.
