I’ve converted the bulk of the lawn on my lot back to prairie/woodland opening, and I feel like everyone is much more chill. I now have wasps, yellowjackets, and of course bees amicably buzzing around, in addition to the WASPs telling me how much they like it.
I would be super interested in this too! There has to be a citizen science project about this. Probably, you could look at native plant citizen science datasets and roughly extrapolate soil conditions from the presence of preferential plants. Although so much prairie/native restoration around me is just a few very hardy grasses at this point with a few ruderals like asters and goldenrods that will grow literally anywhere in my region lol.
