I thought no-till was a thing because soil erosion was becoming a crisis, the co2 storage just seemed like a bonus. The research focused on commercial corn and soy farms, the insane amount of pesticides used probably say more about commercial farms than about no-till in general.
Then they reference some meta analysis that has mixed results about co2 storage.
Idk man, imma put this one in the keep an eye on it until a subject matter expert chimes in pile.

Edit: so Dr. Eldridge that wrote the article has a PhD in soil science, so I assume he knows wtf he is talking about. I still think the takeaway here is commercial farms are run by greedy bastards and maybe the way we define what counts as no-till is just as dumb as the way we define "organic food".
