I like it! I’ve heard guys burn down clover cover crop for N needs and that works. The other thing about clover is it usually comes back no matter what u hit it with - almost.
The tricky part on above.... 2 things... 1) all that Clover residue & stolons will be tough to plant through. Even if band spraying. But- it likely is accomplished there with some row cleaners or maybe they did get it killed off enough in the rows for no till coulters to get through.... & didn’t have too much residue for corn seed to grow through. 2) that band spraying for a small strip for each row- I’m sure they have a special Tip for sprayer & General gps/auto steer to plant in that band. So- not incredibly complex but not stuff a food plotter would have. May be able to eyeball it though.
very cool & I believe it would work. Or a version of it. So great for soil on a dozen fronts, drought, cost savings, etc.
