For some producers, high fertilizer nitrogen (N) prices will add significant costs to corn production this year. What management options can producers take to get the most return from added N? Where to apply N and at what rate? Allocate more N to where it is needed most. If your N costs are high, or products are in short supply, then allocate more N to the situations with greatest potential response to applied N. This allocation would be to the most responsive crops and rotations.
