The Economic Advisability of Lowering 2019 Nitrogen Application Rates on Corn
By Gary Schnitkey & Laura Gentry
Spring field operations will soon begin, and nitrogen applications on corn will commence. More nitrogen will be applied this spring than is typical because wet weather limited fall applications. University-recommended nitrogen application rates in Illinois are between 140 and 180 pounds of actual nitrogen per acre for corn-following-soybeans. For farmers applying above those rates, application reductions seem prudent this year. If a farmer is uncomfortable lowering to the University-recommended rates, experimenting by leaving strips in fields seems prudent.
