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 […]

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
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.



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 […]

I had the chance to tag along to the Jefferson airport with the crew from Stott Aerial Spray and Bill Frederick of Iowa Cover Crop last week to shoot some footage for some upcoming cover crop videos we are producing. I cut together a little snippet, and thought some of you would be interested. For more info on where […]

For those who missed the field day on soil regeneration hosted by Chris & Janenne Teachout near Shenandoah on Aug. 29, or for those who want to re-acquaint themselves with some of it, check out the “highlight reel” we’ve compiled below. The video features Chris, as well as Dr. Jill Clapperton, discussing cover crop practices […]

In Iowa corn-soybean production systems, cover crops are typically aerially seeded into standing crops around the time of physiological maturity or drilled immediately following corn or soybean harvest. Previous on-farm research conducted by Jack Boyer has shown that seeding cover crops earlier in the fall can translate to greater fall and spring biomass. This may present […]

This week on the show, we had Chris Teachout, who farms near Shenandoah in southwest Iowa with his wife Janenne. Chris is a fifth-generation farmer, and he and his family have been using conservation practices on their farm since the mid-80s. He raises corn, soybeans and small grains, and has been using no-till practices for […]
