Considerable adoption of broadcast (spraying) of UAN exists in certain areas of the province. At planting time this often occurs as a flat fan application in combination with soil applied herbicides. Later in the season there is increasing use of streamer nozzle techniques to apply UAN when the corn is in the 3-6 leaf stage.

The purpose of this project is to evaluate the impact of applying UAN at various times and with various application (broadcast vs. injected) strategies.
