Any reason why joint compound can't be worked into the soil to add in

toss it out, when I could toss it on the compost pile or toss it in the

Here is the URL for an MSDS page for drywall compound.

It's mostly gypsum, here we buy that to add to our soil. It depends
where you are and the condition of your soil whether it would be good
or bad. In any event, nothing bad will happen if you mix it in with
the soil.

Thanks for the link, I didn't know the composition amounts. I was concerned
about the EVA portions, but looking at the concentrations they're far too
small to matter in the amounts I'm looking at.

So what is Perlite good for anyway? (so far as plants are concerned anyway)
