Extending and diversifying a crop rotation
to include a small grain presents
farmers with the opportunity to also
include green manure cover crops.
• Three farmer-cooperators grew a small
grain + red clover and a small grain +
cover crop mix preceding corn in their
• Red clover frost-seeded with the small
grain put on more aboveground biomass
and contained more N than the
cover crop mix seeded after small grain
harvest on one farm.
• Corn yields following red clover were
greater than those following the cover
crop mix at only one farm.
• If sufficiently terminated, red clover and
the cover crop mix preceding corn in
rotation can result in yields comparable
to county yield averages.
