Soybean School: Wrestling residue in no till systems

What’s the best way to manage corn residue to mitigate soybean yield loss in a no-till system?

That's a question University of Wisconsin Madison soybean specialist Shawn Conley hears more and more from growers as both corn yield and the biomass produced by more prolific hybrids continues to grow.

On this episode of the RealAgriculture Soybean School, Conley shares results from a Wisconsin trial designed to assess different methods of corn residue management in no-till soybeans. He says a second year of research will help provide more conclusive insights, but 2022 results indicate that chopping corn residue in the fall or spring prior to planting produces better yields than straight no-till. The research also indicated that soybean yields take another jump when nitrogen (30 lbs in this trial) is applied in the spring.
