“Why isn't human waste being used”

It has pathogens that manure doesn’t. The pathogens can be consumed by anaerobic digesters so that the poop can be safely used as fertilizer.

I'm actually all in on no-dig/till and permaculture/ regenerative agriculture. Move away from growing g annual crops as staples and eat seasonally as the perennial crops come in.

Growing grains is what got us here on the first place.

I'd settle a rotational system such as Gabe Brown uses in North Dakota.
