A Wisconsin crop consultant says farmers noticed something unexpected in a cornfield with interseeded cover crops.
Matt Oehmichen with Short Lane Ag Supply in Colby, Wisconsin tells Brownfield the silage corn was planted in 60-inch rows with interseeded cover crops that could be grazed after the silage harvest in 2020. He says in this case, there was better cover crop growth where the corn rows went north and south. “So then this year, we all paid particularly close attention and wouldn’t you know it, with the season that we had, you see a little bit more growth in that north and south.”
Oehmichen says there are no scientific studies to explain this, but he believes the interseeding was applied after V4, and the corn never stopped growing, limiting the cover crop growth.
