Maybe you can find a soil science class online.

Probably one at MIT - but maybe under a different label.

It's worth learning how to do simple assays.

In my case I would have to re-build an enclosed area to keep the animals out.

Classic initial technique is a pyrex beaker/ measuring cup full of hydrochloric acid, into which the soil sample is dumped. This won't dissolve Copper or Gold (without special extra measures like Chlorine gas), but it will dissolve Zinc, Iron, and maybe Uranium.

There used to be a chemical analysis place in Nevada that did some samples.

During Covid19 they increased their minimum to a large number, like you had to buy 100 tests at a time.

Very cool! I am going to look into this!
