Soybean School: Planting no till soys after a BIG corn crop

- What impact do higher-yielding corn crops have on no-till soybeans?
That's a question many growers are asking as they prepare to plant no-till soybeans into high levels of corn residue that can keep soil cooler in spring, impact emergence and reduce stands. Growers also have to contend with soil compaction caused by difficult harvest conditions that can hinder soybean growth.
On this episode of the RealAgriculture Soybean School, Ontario Ministry of Agriculture, Food and Rural Affairs soil management specialist Jake Munroe joins host Bernard Tobin to share his take on how big corn crops affect no-till soybeans.
In 2022, Munroe followed a series of no-till soybean fields to determine how a record 2021 Ontario corn yield, and a wet, difficult harvest season that produced significant soil compaction, impacted the following soybean crop.
In the video, Munroe shares how he monitored five fields in southwestern Ontario, spanning three counties - Huron, Wellington and Brant. Each field had been under a reduced tillage system across the full rotation for seven years or more.

Not saying it’s the right way to do it, or the right way for you, but I drill an ancient grain wheat behind that corn, mixed with a multi species cover crop that will winter terminate, get a couple of grazing passes, then drill in yellow pea when the ground is semi frozen during the day, and more frozen at night. Then I harvest the cereal and pea together, clean and separate.
Follow,that with warm season grasses, make several grazing passes, drill cereal rye with winter terminating species, and beans the following spring. I’d love to go with beans after the corn, but haven’t had good luck with wheat varieties after rye. Too much volunteer rye, and rye is my silver bullet for soybeans and edible beans. I get massive nodulation, and then it starts feeding the beans just when it needs it. Both EB’s and soybeans are the only things I grow with organic yield drag. Not messing with what works for me until it stops working.
I get hammered pretty hard on corn. The no til, planting green and organic is the perfect storm. But boy, I get a better, far more palatable product. Yellow dent corn has degenerated in to empty calories. It’s just filler that has to be heavily fortified because it can’t perform on its own as a feed product. What’s scary, is on the people food side, commodity purchasers could care less. When sold as a feed product for livestock, you’re dealing with PhD’s, and you can work out a lot better price if you have some protein and nutrients in your product. But the same company will buy for human consumption, and could care less.
Non chopping and no till. If you plan on tillage then chopping helps residue flow. I was a young buck looking at new corn heads and my dad immediately said we're not getting one of those chopping heads. He had seen people really screw themselves for next year.
Seems to me that nonchopping corn head is better to get a good stand. That is how we notill .
