Description

Yearly nitrogen (N) input is typically required for optimal corn yields in the majority of Iowa crop rotations. The exception would be first-year corn following established alfalfa where none to only a small N input is typically needed. If not fertilized with N over time, corn yield will be very limited as the soils ability to supply plantavailable N becomes depleted.
