I'm not even on the stupid part of the dunning-kruger curve when it comes to ag but I think nitrogen used in fertilizer is kind of a big problem? Or, it's a much worse greenhouse gas than carbon dioxide, although even just from a quick google it looks like it may be pound for pound worse but accounts for far less than carbon dioxide.
Either way, that's a thing too. I'd be interested if an @Al_4_ISU could comment generally (sorry to tag you buddy although actually I am interested) but I think generally there are a lot of farmers who are interested in adopting more "green" practices when it comes to stuff like cycling and fertilizing and what have you but the in general (and especially one with as... complicated of a landscape of regulation and incentivization/etc) there needs to be policy that helps support those kinds of choices economically. I know there's a lot of incentives around carbon intensity in ethanol production (which I think is state by state and California leading the charge) but I'm not sure how well that trickles back to the "planting crops" phase of decision making.
Again, I know just enough to be incredibly stupid on this topic but am curious about it.
