Direct product answer
What is fertilizer-grade DAP?
Diammonium phosphate is a concentrated ammonium phosphate fertilizer supplying nitrogen and phosphorus for direct soil application and fertilizer blending.
18-46-0 is a common fertilizer designation; supplied analysis varies Chemical identity alone does not establish fertilizer grade, nutrient guarantee, solubility, crop suitability or market registration. Compare the offered source against the required label and agronomic program.

Authoritative context
Review FAO plant-nutrition guidance, FAO fertilizer specifications guidance and NIH PubChem chemical records. Agronomic suitability and fertilizer registration remain crop, soil, formulation and jurisdiction specific.
Agronomic note: This supplier page does not prescribe nutrient rates or establish crop suitability. Base fertilizer selection and application on soil, water and tissue data, qualified agronomic advice, compatibility testing, the approved label and local environmental requirements.
Storage and handling
Handle DAP under the current SDS
- StorageKeep packaging closed and protect the exact grade from moisture, contamination and incompatible materials.
- CompatibilityBench-test dissolution and mixing order; concentrated calcium, magnesium or micronutrient solutions may precipitate with phosphate.
- Workplace controlsFollow the current SDS for dust control, PPE, spill response, transport and disposal.
Fertilizer buyer questions
DAP fertilizer FAQ
What is DAP used for in fertilizer products?
Diammonium phosphate is a concentrated ammonium phosphate fertilizer supplying nitrogen and phosphorus for direct soil application and fertilizer blending. Use should follow soil or tissue testing, crop recommendations and applicable fertilizer rules.
What nutrient grade should buyers request for DAP?
18-46-0 is a common fertilizer designation; supplied analysis varies. Request the current source-specific guaranteed analysis and confirm whether nutrients are expressed as N, P2O5 and K2O or on another legally required basis.
Why is there no public DAP specification?
Bespring Chemical does not publish fertilizer product specifications online. Contact sales for the current source-specific specification or TDS, analytical methods and representative COA.
Is this the same as food-grade DAP?
No grade is established by the chemical name alone. Fertilizer, food and technical products have different intended uses, documentation, impurity controls and regulatory requirements.
What should a DAP fertilizer RFQ include?
Provide the exact identity and form, required guaranteed analysis, fertilizer application, quantity, packing, destination, registration documents, Incoterm and delivery date.
