There is an interest in better understanding nitrogen (N) placement during sidedressing and the potential effect on N uptake and yield.
Nitrogen is a substantial cost in corn production. Understanding the optimal placement of sidedressed N can help farmers determine the application method best suited for their operation.

At this location, no clear advantage to either N application method has been seen at V6.
This year at this location dry conditions followed application, but the data shows no effect with applying the N directly beside the row.
The timing for a rolling coulter application can be limited due to the height of the corn crop.
360 Y-DROP® can allow a wider application window for sidedressing later in the season.
Yield differences may not be economically feasible when all costs are considered. Consider all local costs when making N management decisions.
Individual corn products may have different responses to N application timing. Consult your local Field Sales Representative or Technical Agronomist for recommendations.
