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 […]

50 farmers and others met up at the Holland City Park on the evening of June 8th to learn more about how Fred Abels has made two farming practices, strip tillage and cover crops, work for him. After enjoying a supper of cheese hamburgers, baked beans, fruit and cookies prepared by PT Grillers the crowd […]

While farmers have been getting busy planting, we PFI staff have been getting to work writing up resources to make sure the 2017 season is the best yet for cover crops. Check out these three NEW resources for farmers and crop advisers on the latest recommendations for cover crop selection and best management practices. Cover […]

On Thursday April 6, fifty-one attendees gathered in the Leighton Town Hall for a cover crop field day hosted by Ward Van Dyke. After tucking into a delicious lunch organized by Sandi Van Dyke, we dove into the management and benefits of cover crops. We stayed indoors and had several presentations inside to kick off […]

“We have an infiltration problem, not a runoff problem.” This Ray Archuleta quote was much discussed on third and final installment in the American Society of Agronomy’s 2017 webinar series “Cover Crops – Looking Beyond the Basics.” The webinar, which took place on February 9, featured Anne Verhallen, a soil scientist from the Ontario Ministry of […]

Are you grazing cover crops this spring, or plan to in the fall? If so, it’s important to check and see if your corn or bean herbicides have grazing restrictions. Some common herbicides do not allow for grazing of cover crops or crop residue. If you’re grazing covers this spring, look back at what herbicides […]

On Thursday February 2, Practical Farmers held a cover crop field day at Whiterock Conservancy in Coon Rapids, Iowa. Thirty or so attendees at the field day tuned in to the second webinar in the Agronomy Society of America’s “Cover Crops 2017 – Looking Beyond the Basics” series sponsored by SARE. Practical Farmers member Chris […]

In a Nutshell
• Delaying cover crop termination until
near soybean planting would allow
for more biomass production by the
cover crop in the spring presenting the
opportunity for more environmental
• Two farmer-cooperators continued
work they began in 2015 that compares
terminating a cereal rye cover crop 2-3
weeks prior to seeding soybeans (early
termination) with terminating the cover
crop within 5 days of seeding soybeans
• Jeremy Gustafson saw a 2 bu/ac increase
and improved weed control with
the late termination treatment in 2016.
This amounted to a $49.97/ac economic
benefit compared to the early termination
treatment. In 2015, soybean
yields were equivalent between the two
termination date treatments.
• Jack Boyer saw no difference in soybean
yields between the two cover
crop termination treatments in either
year. In 2015, he was able to skip a
post-emergence herbicide application
which saved him approx. $40/ac.

• This project tested the effect on
over-wintered garlic yield of planting
date and two mulching strategies:
companion-seeded oat cover crop vs.
• Farmer-cooperator Mark Quee planted
garlic in September with a companion
oat cover crop (oat residue following
winterkill intended to serve as mulch).
Garlic planted in October was mulched
• September-planted garlic had higher
yield than October-planted, but pervasive
rot in several areas of the field
may have impacted results.

In a Nutshell
• Cover crops and summer annual
forage mixes can provide a host of
benefits to annual cropping systems:
add biodiversity, reduce soil erosion,
reduce nutrient loss, increase soil
organic matter and reduce weed pressure.
• Dave and Meg Schmidt evaluated the
effect of applying chicken litter to a
cereal rye + hairy vetch cover crop
and grazing the cover crop ahead of
establishing a summer annual forage
• Grazing the cereal rye + hairy vetch
cover crop resulted in more biomass
production than where not grazed.
• The application of chicken litter did
not affect cover crop growth or summer
annual forage biomass production.
• Hairy vetch in the cover crop successfully
established (seeded in late August
2015) and may have contributed a
substantial amount of N to the succeeding
summer annual forage crop.
