>> Sigh, this does NOT seem like something that should be done in excess.
Especially if your soil was built up from straight horse poo.
I've read about pregnant women in the American South eating clay, and other people making a big fuss about its dangers. I don't know.
>> happen to come across a link to that study, I'd love to see it.
I heard it as an anecdote from some Yalie when i worked in the Nutrition & Food Science Dept. at MIT. The Yale study I heard about would have occurred before, or much before, 1974. I was guessing in the late 1950s or 1960s.
Here's a debunking opinion, a claim that only "tiny amounts" of vitamins could be gotten from soil. Despite calling himself a "scientist", he announces his opinion as a fact without citing any evidence:

Here's another indirect anti opinion. He thinks there are racial differences in vitamin requirements, at least as regards ability to survive on vegan diets:
He also thinks that vegan diets are "too yin" and "Very low in etheric energy".
So your mileage may vary.

Maybe the book he is debunking ("The China Study (2006) ") has a mention of the Yale study. Despite debunking it, he doesn't provide an ISBN number or link or publisher.
