The resulting growth seems almost magic for in a few weeks both the
buckwheat and cow-peas are in bloom and the growth becomes so rank and
dense that it is difficult if not actually impossible to progress far
into the field afoot. Just before the seed ripens this growth is rolled
down, cut up with disc and plowed under. The buckwheat adds humus and
the cow-peas, (another legume), both humus and additional nitrogen.
After this has been thoroughly worked into the soil and a perfect
seed-bed again formed fall has arrived and the ground is seeded to oats.
