Look, there's really no argument to be made. Generalizations are rarely true and that's all we have here. There are many production systems being used, and, so far as systems are concerned, in the long run they all must be profitable. System changes do occur, but slowly. That's not necessarily because of resistance to change, but primarily because of the large fixed investments required. Once I decide to buy a no-till drill I'm not changing my mind about it next year because you say I can produce more bushels at a lower cost. I'm listening, but it takes a long time to change course. Yes, in many circles here in my state, the mindset is changing. Cover crops are nearly everywhere for any number of reasons, including but not exclusively because of the benefits of "regenerative" agriculture.
In the midwest this year, crops got planted late and now it's freezing and snowing as harvest continues. I doubt there will be much attention paid to planting cover crops...let alone figuring out which production systems produce the most product at the least cost. That's to be left to the academicians. I'm not disparaging it. I used to be one. Point is, there's theory and the real world, and the best of us do our best to implement theory when it makes sense. It takes time, sometimes a lifetime.
