If they take prevent plant corn there is a restriction on what can be planted as a cover crop, soybeans are a no. Most guys I’ve talked to that have the ability to make hay or have cattle are leaning towards oats, it can’t be harvested till after November 1. But most farmers no longer have cattle and/or hay equipment, going to be a small percentage that can take advantage of that.
I guess the days of "do it all farmers" are gone. Now you have to pick one or two things.
I remember my dad (as a kid) had hogs, dairy, sheep, chickens - plus the 80 acres.
