We drill most of our plots, have a couple we can't get the drill into. We mix oats, rye, radish in the large box and clovers in the small.
Per acre we do 50# each of rye and oats, 3# radish and 10-12# mix of Crimson, arrow leaf and med red clover. We haven't been using white clovers because we are following up the fall plots with high carbon summer plots to build OM in our poor soils common in the north part of the state.
