Urea DAP usage timing basal top dressing, nitrogen phosphorus dose.
Should I use urea or DAP first, and how much per acre?

DAP is mainly a basal phosphorus fertiliser (18% N, 46% P2O5) applied at or before sowing and placed near the seed zone, while urea (46% N) is the main nitrogen source applied partly basal and mostly as split top dressings during active growth. A common mistake is using too much DAP for nitrogen; if you need nitrogen later, use urea, which is cheaper per unit N. The exact per-acre quantity depends on your crop and soil test, so follow your Soil Health Card. Do not mix urea and DAP and store them together for long. Avoid broadcasting urea on dry soil in hot afternoons to reduce volatilisation losses; apply before irrigation or light rain.

My father used to dump DAP for everything. Once I split urea into three doses my wheat tillering improved and I used less total fertiliser.

If your soil test already shows phosphorus as high, you can cut back on DAP and lean on urea plus SSP. I was applying DAP every season out of habit until the card showed my P was piling up.

For top dressing urea, I always time it just before irrigation so it washes into the soil instead of sitting on the surface and gassing off in the heat. Adjust amounts to your Soil Health Card and KVK and do not over-apply.
