Farms have been producing their own fertilizer for centuries. ;-)

Yeah I know. Wasn't talking about that.

https://phys.org/news/2021-02-plasma-technology-world.html https://portal.nifa.usda.gov/web/crisprojectpages/1025777-lo... https://pubs.acs.org/doi/10.1021/acssuschemeng.2c06357 (paywalled)

"plasma" and "NOx" seem to be the keywords here (so other process than discussed here).

Not at scale (yet), cost unclear. But the technology exists, and being improved upon.

Yes, and yields were crap back then. Guano and then synthetic fertilizer changed everything.
