A team of soybean researchers says a little pre-plant nitrogen might help.
Mark Kendall with the University of Wisconsin tells Brownfield they’ve been looking at conventional and no-till soybeans following corn. He says seedlings have more corn residue to grow through, and having some nitrogen for the new seeds helps in some cases. “We’re finding with some of the research, especially in our wider soybean planting, 30-inch rows for example, we’re finding a little bit of a benefit to plan a small amount of nitrogen pre-plant in the springtime, so 30 pounds or less.”
Kendall says there was a measurable yield difference in fields with wide soybean rows.
