Cover crops are nothing new, just being re-marketed to large , all arable farms who forgot what good a rotation including catch crops for livestock did.
I have always grown stubble turnips or some form of fodder crop , sown after winter barley and grazed off before spring sowing.
Maybe the small mixed farms should be the ones payed more, rather than the barley barons who ripped out all the hedges in the 70s and 80s and depleted their soils due to monoculture.
Don't believe your re- inventing the wheel!
