Chemical Composition and Nutrient Characteristics
Nitrophosphate 24-24-0 is manufactured by reacting rock phosphate with nitric acid. It supplies nitrogen in two distinct chemical forms—nitrate nitrogen and ammoniacal nitrogen—alongside citrate-soluble and water-soluble phosphate.
This dual-action nitrogen profile provides both immediate seedling uptake and sustained root feeding.
- 24% Total Nitrogen: Contains balanced fractions of fast-acting Nitrate Nitrogen (NO3-N) for immediate uptake and Ammoniacal Nitrogen (NH4-N) for extended availability.
- 24% Phosphate (P2O5): High-analysis phosphorus that fuels early root branching, cellular energy transfer (ATP), and uniform vegetative establishment.
- Chloride & potash free: Ideal for soils naturally abundant in exchangeable potassium or when potassic fertilizers are applied separately.
- Uniform granulate: Homogenous, dust-free granules ensure even mechanical drill or broadcast distribution across fields.
Application Guidelines and Recommended Crops
Nitrophosphate 24-24-0 is most effective when applied as a basal starter fertilizer at the time of final harrowing or drilling.
Incorporating into the root zone ensures early accessibility to germinating seedlings.
- Recommended crops: Highly suited for sugarcane, wheat, paddy, cotton, maize, and commercial fruit orchards.
- Soil placement: Band or drill fertilizer 5 cm below seed depth to prevent salt injury while ensuring rapid root interception.
- Potassium pairing: Supplement with Muriate of Potash (MOP) or SOP in potassium-deficient soils based on Soil Health Card recommendations.

Common questions
What nutrients are present in 24-24-0 fertilizer?
It contains 24% Nitrogen (both nitrate and ammoniacal forms) and 24% Phosphate (P2O5), with zero potash.
What is the advantage of nitrophosphate fertilizers like 24-24-0?
They provide fast-acting nitrate nitrogen alongside ammoniacal nitrogen, delivering immediate starter nutrition and sustained root development.
Can 24-24-0 replace DAP as a basal fertilizer?
Yes, in soils with adequate potassium, 24-24-0 provides an excellent balanced ratio of nitrogen and phosphorus for basal crop establishment.
