RE: Clover ????'s
Ladino is a tall growing (and the best) variety of white clover. It lasts longer than red clover with more foliage. The problems if you don't mow it are that the weeds will take over and the clover gets woody after it matures. You'll also get a lot a tree seedlings trying to repopulate the field. If the deer graze it or you let the cattle graze it after it matures it'll have the same effect. You could try a system similar to rotational grazing where you let the cows keep it down on a routine timetable. Just let them harvest it with time left for regrowth before the fall.
