NEWS RELEASE

Successfully raising corn after a cover crop requires timely cover crop termination and N fertilization. Commonly, farmers terminate a cover crop 2-3 weeks prior to planting corn but generally do not need to apply any more N than if they did not use a cover crop. Last year, PFI farmer-cooperator Dick Sloan attempted “planting green”: planting […]

Successfully raising corn after a
cover crop requires timely cover
crop termination and N fertilization.
Commonly, farmers terminate a cover
crop 2-3 weeks prior to planting corn
but generally do not need to apply any
more N than if they did not use a cover
crop.
• Farmer-cooperators Dick Sloan and
Tim Sieren compared terminating their
cover crops approx. 3 weeks prior to
planting corn with terminating their
cover crops within 3 days of planting
corn. They also investigated N fertilizer
timing and rates across the cover crop
termination dates.
Key Findings
• Delaying cover crop termination
until a few days before planting
corn increased cover crop biomass
production in the spring.
• Terminating the cover crop a few
days before planting corn generally
resulted in reduced yields at both farms
regardless of N strategy.
• Fall manure with 35 lb N/ac at corn
planting and 90 lb N/ac at side-dress
resulted in no yield drag at Sloan’s
when the cover crop was terminated 3
days before planting corn.

 

RESEARCH REPORT

The Iowa Department of Ag and Land Stewardship announced today that they will be working with the Risk Management Agency and crop insurance companies in Iowa to reward farmers who are using cover crops on their farm. Farmers who have planted cover crops this fall or plan to still put out cereal rye on cornstalks […]

Increasing rates of cover crop use on rented ground is the next frontier in improving water quality, promoting soil health and improving farmers’ resilience and not all of this rented land is privately owned. Local, state, and federal agencies own a large amount of land in the U.S. for the purpose of protecting natural resources and providing public infrastructure […]

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. In the past two years, farmer-researchers Jeremy Gustafson and Jack Boyer have documented reduced herbicide use when planting soybeans into a tall, thick cereal rye cover crop that they chemically terminated […]

• 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
crop.
Key Findings
• 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.

 

RESEARCH REPORT

A group of farmers traveled to Ohio in August to spend a day at Dave Brandt’s farm. This blog accompanies the article in the Autumn 2017 Practical Farmer “Members Reflect on Lessons Learned in Ohio.” By Sally Hertz Gran In this reflection, I will be highlighting some of the topics we dug into during the […]

In my article for the latest issue of the Practical Farmer, our quarterly newsletter, I focused on buckwheat (Fagopyrum esculentum), some of the farmers who grow it, and its culinary uses. Many farmers grow the crop as a cover crop, because it’s pretty easy to grow, can suppress weeds, and research has shown it can […]

In a Nutshell
• Can frost-seeding small-seeded
brassica species into crop residue
be an effective spring cover crop
strategy?
Key Findings
• Among three locations, mustard
provided the most groundcover.
• When frost-seeded in the spring,
cover crop growth appears to be
related to GDD accumulated prior
to termination.
