Plan for No-till Soybean

By Mark Licht

Save money and time this fall by planning for no-till soybean planting next spring. Many farmers are moving away from tillage, due to a host of detrimental environmental factors involved with tillage as well as reducing cost of soybean production.

Soybean yields are not impacted by no-tilling. There is no need to spend labor and fuel incorporating the corn residue. Additionally, spring tillage operations are not effective for breaking soil compaction. In fact, the opposite happens in normal spring conditions when soil moisture is plentiful. Spring tillage in wetter conditions leads to smearing soil with the tillage knives or sweeps and disking creates a compaction layer while sizing residue.

One of the most important aspects of no-till planting is to ensure the proper function of the planter. Any planter purchased in the last 10 to 20 years can plant soybean seeds into corn residue, especially if the planter has row cleaners and has been properly maintained. Nearly all planters can ensure appropriate down pressure and seed depth placement.

Research from across Iowa shows that soybean yield is not influenced by tillage system. Therefore, no-till planting soybean into corn residue will yield like other tillage systems but also result in high economic returns. Moving to a no-till system can save $15 to $25 per acre in reduced tillage costs.

Using your combine to prepare your residue for spring can help create a uniform seedbed for planting the following season. Non-uniform spreading of corn residue across the harvest width results in uneven warming and drying of the soil. It can also affect planter performance as the planter moves from areas with higher to lower residue amounts.

Other considerations:

  • Wait for correct soil conditions to plant soybean.
  • Start small and check planter performance often to gain confidence.
  • Use row cleaners to move residue but NOT make a trench.

Why Your Food Future Could be Trapped in a Seed Morgue

Video: Why Your Food Future Could be Trapped in a Seed Morgue

In a world of PowerPoint overload, Rex Bernardo stands out. No bullet points. No charts. No jargon. Just stories and photographs. At this year’s National Association for Plant Breeding conference on the Big Island of Hawaii, he stood before a room of peers — all experts in the science of seeds — and did something radical: he showed them images. He told them stories. And he asked them to remember not what they saw, but how they felt.

Bernardo, recipient of the 2025 Lifetime Achievement Award, has spent his career searching for the genetic treasures tucked inside what plant breeders call exotic germplasm — ancient, often wild genetic lines that hold secrets to resilience, taste, and traits we've forgotten to value.

But Bernardo didn’t always think this way.

“I worked in private industry for nearly a decade,” he recalls. “I remember one breeder saying, ‘We’re making new hybrids, but they’re basically the same genetics.’ That stuck with me. Where is the new diversity going to come from?”

For Bernardo, part of the answer lies in the world’s gene banks — vast vaults of seed samples collected from every corner of the globe. Yet, he says, many of these vaults have quietly become “seed morgues.” “Something goes in, but it never comes out,” he explains. “We need to start treating these collections like living investments, not museums of dead potential.”

That potential — and the barriers to unlocking it — are deeply personal for Bernardo. He’s wrestled with international policies that prevent access to valuable lines (like North Korean corn) and with the slow, painstaking science of transferring useful traits from wild relatives into elite lines that farmers can actually grow. Sometimes it works. Sometimes it doesn’t. But he’s convinced that success starts not in the lab, but in the way we communicate.

“The fact sheet model isn’t cutting it anymore,” he says. “We hand out a paper about a new variety and think that’s enough. But stories? Plants you can see and touch? That’s what stays with people.”

Bernardo practices what he preaches. At the University of Minnesota, he helped launch a student-led breeding program that’s working to adapt leafy African vegetables for the Twin Cities’ African diaspora. The goal? Culturally relevant crops that mature in Minnesota’s shorter growing season — and can be regrown year after year.

“That’s real impact,” he says. “Helping people grow food that’s meaningful to them, not just what's commercially viable.”

He’s also brewed plant breeding into something more relatable — literally. Coffee and beer have become unexpected tools in his mission to make science accessible. His undergraduate course on coffee, for instance, connects the dots between genetics, geography, and culture. “Everyone drinks coffee,” he says. “It’s a conversation starter. It’s a gateway into plant science.”
