Question: 1 / 400

What is the guaranteed analysis for diammonium phosphate?

18-46-0

Diammonium phosphate (DAP) is a commonly used fertilizer known for its high nutrient content. The guaranteed analysis indicates the percentage of nitrogen, phosphorus, and potassium (N-P-K) in the fertilizer. For diammonium phosphate, the analysis is expressed as 18-46-0, meaning it contains 18% nitrogen, 46% phosphorus (as P2O5), and no potassium.

The nitrogen component is provided by the ammonium and is beneficial for promoting leafy growth in plants. The phosphorus content is significant for root development and flowering, making DAP particularly valuable in early plant development and in crops that require ample phosphorus.

Other options reflect different fertilizers or blends that do not contain the same nutrient ratio as DAP. For example, options that indicate lower nitrogen content or varying levels of potassium are characteristics of other formulations, indicating why those would not be appropriate as the analysis for diammonium phosphate.
