Apparently the old stuff I got out of the house when I remodeled didn't, because my microbes aren't suffering.

And I have earthworms everywhere in the garden this year. Not tilling seems to have made quite a difference there.

No tilling is absolutely my favorite - and for the reasons you describe: the soil flourishes. Plowing is fun, and freshens things up, but not everyones soil benefits from plowing.
I am glad that your soil retained its vitality. The more I think about it, the more I think the sheet-rock MUD contains formaldehyde. Why in the world they have to put formaldehyde in sheet-rock mud and shampoo is beyond me.

I used to think all earthworms were the same, but I guess that some species are more desirable than others.
