Monoammonium Phosphate MAP 12-61-0
Premium agricultural-grade Monoammonium Phosphate MAP 12-61-0 for fertigation and high-performance fertilizer formulations
Ihumate Monoammonium Phosphate is a high-purity, fully water-soluble crystalline nitrogen-phosphorus fertilizer raw material with total nitrogen > 12% and water-soluble phosphorus pentoxide > 61%. Its rapid dissolution, low salt index and mildly acidic solution make it suitable for seedlings, transplant recovery and early root establishment, as well as water-soluble, liquid and foliar fertilizer production.
1. Concentrated available phosphorus: Supplies readily available phosphorus for root development, energy transfer, flowering preparation and uniform early growth, together with ammoniacal nitrogen.
2. Built for precision nutrition: Uniform white crystals dissolve into a clear solution for fertigation, sprinkler irrigation, foliar feeding and fertilizer blending. Because MAP contains no potassium, formulators can set potassium independently for each crop stage.
3. The Ihumate advantage: Batch control covers nitrogen, phosphorus, moisture, pH, solubility and appearance. Ihumate supports consistent particle size, export documentation, bulk supply, formulation guidance and 1-25 kg OEM packaging.
Compatibility: Do not combine concentrated MAP stock solutions with calcium or magnesium fertilizers because insoluble phosphates may form. Use separate A/B tanks or separate application times, and conduct a jar test before new fertilizer or pesticide tank mixes.

Frequently Asked Questions
1
Why is MAP 12-61-0 suitable for seedlings and root establishment?
MAP supplies concentrated water-soluble phosphorus together with ammoniacal nitrogen. Phosphorus supports energy transfer and root establishment, while ammoniacal nitrogen supports early vegetative growth, making MAP useful around transplanting and early development.
2
Can Monoammonium Phosphate be used for fertigation and foliar feeding?
Yes. High-purity, fully soluble MAP can be used through fertigation and sprinkler systems and in validated foliar programs. Adjust concentration to crop sensitivity, leaf age, water quality and local label requirements, and test a small area first.
3
Can MAP be mixed with calcium nitrate or magnesium fertilizers in one stock tank?
No concentrated stock-tank mixing is recommended. Phosphate can react with calcium or magnesium and form precipitates that reduce nutrient availability and clog irrigation equipment. Use separate A/B tanks or apply at different times.
4
How does Ihumate support consistent MAP quality?
Ihumate checks nitrogen, P2O5, moisture, pH, appearance and dissolution by batch and supports export customers with COA documentation, OEM packaging and formulation guidance. Contract and batch COA values remain the final guarantee.

Application & Dosage: Monoammonium Phosphate MAP 12-61-0
For fertigation, sprinkler irrigation, transplant starter programs, validated foliar feeding and production of high-phosphorus water-soluble, liquid and NPK fertilizers. MAP supports early rooting but is not a complete nutrition program; potassium, calcium, magnesium and micronutrients should be supplied according to soil, water and tissue analysis.
Agricultural Application
- Seedling & Transplant Stage:Apply through fertigation during root establishment, adjusting the rate to crop demand and existing soil phosphorus.
- Foliar Phosphorus:Use a low-concentration, even spray outside periods of high heat and intense sunlight; test sensitive crops and new cultivars first.
Fertilizer Manufacturing
- Water-Soluble & Liquid Fertilizers:Use as a high-purity N-P source in starter, seedling and custom NPK formulations.
- Professional Blending:Combine with compatible potassium and micronutrient sources; keep concentrated calcium and magnesium solutions in separate tanks.
Application Ratio Scheme
| Crop Name | Growth Stage | Application Ratio |
|---|---|---|
| Fertigation | Seedling, post-transplant or critical phosphorus stage | 2-5 kg/ha per application; adjust to analysis and crop demand |
| Foliar Spray | Early growth or phosphorus correction | 0.5%-1.0%; test sensitive crops first |
| Fertilizer Formulation | Water-soluble, liquid and NPK production | Calculate from target N and P2O5 analysis |
