Any reason why joint compound can't be worked into the soil to add in
nutrients, like calcium, or as a way to control the ph of the soil? I
have
about 3 lbs of the stuff from a previous drywall project and didn't want
to
toss it out, when I could toss it on the compost pile or toss it in the
dirt
to break down.

I can say that old gib board is reprocessed to get the gypsum out of it &
then sold as a soil amendment.
