MINNEAPOLIS — First- and second-year corn following alfalfa usually benefit from increased yield, reduced or eliminated nitrogen requirement from fertilizer or manure, and reduced pest pressure.
Nitrogen management guidelines for first- and second-year corn following alfalfa were updated in 2016 and are available at http://z.umn.edu/fertilizingcorn.
Strategies for successful alfalfa termination to fully achieve rotational benefits are summarized at http://z.umn.edu/rotation.
More educational resources on corn production are available at Extension’s Corn Production website.
