My dad had a tomato garden in the back a couple of years ago. The
garden is still there but he hasn't grown anything in it for a couple
of years. Imagine my surprise when I saw what looked like tomato
leaves. I walked over to see if he'd planted it and I saw a plant with
little black berries. I thought I knew what it was and went back
inside and looked up images, and sure enough, it was nightshade. I
think it's a variety called Black Nightshade but not 100% on the
variety.

We don't really care what's growing back there now as we're not going
to eat it anyway, but I was curious to know if it would be safe to
garden in that soil later. Would the root or leaves or other
decomposed parts of the nightshade plant taint the soil or poison the
soil around the plant?

I'm not an expert, but given that tomatoes are in the same family as
nightshades, I'm not surprised they'd grow where tomatoes did. I presume the
soil would be safe for anything that likes the same kind of soil tomatoes
do. I would recommend getting rid of the nightshade plant though(by burning
it), just so no unsuspecting critter or child eats them in the future, and
to prevent it from spreading.
