This year marks the 30th anniversary of Practical Farmers of Iowa’s Cooperators’ Program—our vehicle for conducting on-farm research trials. As such, throughout this year we’ll periodically be taking a look back at work done by farmer-cooperators over the past 30 years in a series of blog posts entitled “Better Know an On-Farm Research Project.” In […]

RESEARCH PROTOCOL

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
crop rotations.
KEY FINDINGS
• 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.
