What is fertilizer-grade MAP?
Monoammonium phosphate is an ammonium phosphate fertilizer supplying nitrogen and phosphorus for direct soil application, bulk blending or suitably qualified soluble-fertilizer systems.
11-52-0 is common for granular fertilizer; soluble grades may differ 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.

Procurement checklist
How to source fertilizer-grade MAP in bulk
Compare the offered grade, application requirements and commercial terms before requesting a sample or placing an order.
Quotation and delivery basis
Compare source-specific specification, nutrient declaration, current COA, packing, Incoterm and delivery window.
Application and process requirements
Where relevant, confirm solubility, insolubles, source-water compatibility, stock concentration and crop program.
Technical and quality documents
Request SDS, private specification or TDS, representative COA, batch COA, traceability and destination-market files.
Application screening
MAP fertilizer application guide
These are qualification areas, not universal crop recommendations, nutrient rates, label approvals or guaranteed agronomic outcomes.
Soil-applied NP fertilizer
Define the phosphorus and nitrogen requirement from soil testing and the crop program. Match the grade to the intended placement and equipment.
Dry fertilizer blends
Compare particle distribution and physical strength with other blend components. Check segregation through the handling route.
Starter fertilizer selection
Use the local agronomist's nutrient and placement recommendation. Product identity alone does not determine an appropriate rate.
Qualified fertigation grades
Use only a grade whose solubility and impurity profile meet the stock-solution requirements. Test compatibility before injection into the irrigation system.
Technical selection
Questions to resolve before approving MAP
Granular or water-soluble grade
State the intended application and physical grade. A granular fertilizer listing does not establish suitability for a concentrated fertigation stock.
Nitrogen and phosphorus basis
Request guaranteed nitrogen and the declared P2O5 fraction with methods. Compare quotations using the same nutrient and moisture basis.
Handling and dissolution
For dry blends, specify granule properties and caking criteria. For solution use, specify insolubles and evaluate the actual water, concentration and temperature.
Market and source documents
Confirm destination registration, label declaration and relevant impurity limits. Review the current source specification and a representative COA.
Private technical documentation
Request the current MAP fertilizer specification
Bespring Chemical does not publish product specifications for this fertilizer raw material online. Contact sales for the current source-specific specification or TDS and confirm its revision, analytical methods and acceptance criteria.
Product documents
Request the signed current specification or TDS, SDS, test methods, representative COA and batch COA.
Nutrient and market documents
Confirm guaranteed analysis, expression basis, labeling, fertilizer registration, trace elements and destination requirements.
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 MAP 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
MAP fertilizer FAQ
What is MAP used for in fertilizer products?
Monoammonium phosphate is an ammonium phosphate fertilizer supplying nitrogen and phosphorus for direct soil application, bulk blending or suitably qualified soluble-fertilizer systems. Use should follow soil or tissue testing, crop recommendations and applicable fertilizer rules.
What nutrient grade should buyers request for MAP?
11-52-0 is common for granular fertilizer; soluble grades may differ. 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 MAP 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 MAP?
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 MAP fertilizer RFQ include?
Provide the exact identity and form, required guaranteed analysis, fertilizer application, quantity, packing, destination, registration documents, Incoterm and delivery date.
