Roller-crimping as a method for terminating cover crops in organic and no-till farms in Iowa is gaining interest, but many questions still remain about best management practices. In this farminar, three Iowa farmers will share their experiences using a roller crimper in their respective organic operations. Scott Shriver and Francis Thicke will focus on cereal rye going into soybeans, and Billy Sammons will share his experience with hairy vetch going into corn.

• Cover crops are gaining new attention
for their ability to reduce weed
pressure in soybeans. Specifically,
when seeding soybeans directly into a
thick cover crop.
• Farmer-cooperators Jack Boyer and
Scott Shriver investigated the effect
of row-width on soybean yields when
rolling a cereal rye cover crop. Boyer
rolled select strips after terminating
with an herbicide; Shriver used a
roller-crimper to terminate his cover
• The narrowest soybean row-width at
both farms (10-in. at Boyer’s; 7.5-in. at
Shriver’s) resulted in greatest yields.
• Boyer saw the greatest return on
investment where he drilled soybeans
in 10-in. rows and did not roll the
cover crop after chemical termination.
The drill itself appeared to lay down
much of the cover crop residue.
