I received my Drovers magazine (Oct 25 issue) in the mail yesterday and was very pleasantly surprised to see an article on a farm in MN taking an interesting approach to combining corn growing AND keeping the ground covered and collecting solar energy:

Growing 200 bu corn like this and increasing soil organic matter from 1% to 3.5% is impressive.

And if many producers raised 200 bu corn like this at a profit we solve several problems at one time.
