Question

Write the percentage of Nitrogen and Phosphorus in diammonium phosphate (DAP).

Hint:

Check fertilizer labels for exact N-P-K ratios before application.

Answer 1

Step 1: Diammonium phosphate (DAP) contains 18% nitrogen (N) and 46% phosphorus pentoxide (P₂O₅), which is equivalent to approximately 20% elemental phosphorus.
Step 2: These values are standard for DAP, a widely used fertilizer providing both nutrients.
