What is Terra Preta for $50?
>>1087171
They did, a lot.
But there are very good reasons not to, chiefly that it's a very efficient way of spreading diseases.

wouldnt realy bet they didnt
but maybe cowshit was just generaly more abundant and far far less of a owerall problem to collect and handle
maybe hoarding up the all the shit of all the people in your longhouse might have been seen as weird, revolting or worse, witchcraft

or "e-coli outbreak in California"
Between 1630 and 1830, the feces of Paris, from the sewers and the cesspits, along with the remains of dead animals, were gathered in one place to dry, and then the stuff was sold as fertilizer.
It was also done before that but in a less organized manner.

We do, even now. It's called night soil.
You could but you'd have to let it compost for a while.
You can also use urine but you'd have to dilute it quite a bit because of the nitrogen content.
