AOLANSU Agricultural Monoammonium Phosphate CAS 7722-76-1 is a water-soluble nitrogen and phosphorus fertilizer developed for growers, fertilizer distributors, and agricultural formulators seeking a concentrated phosphorus source for crop establishment and nutrient management. With the chemical formula NH₄H₂PO₄, it provides nitrogen (N) and available phosphorus (P₂O₅) in one fertilizer, with a typical nutrient ratio of approximately 11-44.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd. in China, the product is produced through controlled ammoniation, granulation, drying, screening, and quality inspection. AOLANSU also holds a Hazardous Chemicals Business License and provides professional documentation and export support for qualified international fertilizer buyers.
Rather than focusing only on total nutrient content, this product is designed around an important agricultural purchasing concern: how quickly and efficiently phosphorus becomes available to crops after application. With water-soluble phosphorus of ≥90%, uniform 2-4 mm granules, and total N+P₂O₅ content of ≥55%, it is suitable for basal fertilization, seed-zone nutrient management, fertigation, and fertilizer blending programs.
Phosphorus is closely associated with early root development, energy transfer, cell division, flowering, and crop maturity. However, the total phosphorus added to soil does not necessarily represent the amount immediately available to plants.
In some soils, especially soils with high levels of calcium, iron, or aluminum, phosphorus can become fixed and less available to plant roots. For this reason, fertilizer buyers often evaluate water-soluble phosphorus in addition to total P₂O₅ content.
AOLANSU Agricultural Monoammonium Phosphate CAS 7722-76-1 provides a highly water-soluble phosphorus source that can dissolve rapidly after application. This makes it particularly useful when phosphorus availability during crop establishment is an important part of the nutrient management strategy.
The ammonium nitrogen component provides an immediately available nitrogen source for early plant development. Nitrogen supports leaf formation, chlorophyll production, and vegetative growth, complementing the phosphorus supplied by the same fertilizer granule.
The high proportion of available phosphorus makes MAP suitable for crop stages where root development and early establishment are important. Adequate phosphorus can support root expansion and improve the plant's ability to explore soil for water and nutrients.
Combining nitrogen and phosphorus in one fertilizer simplifies nutrient planning compared with sourcing and applying separate nutrient products. It can also reduce the number of individual fertilizer materials required in a blending program.
Water-soluble phosphorus is ≥90% of the specified available phosphorus content. This characteristic makes the product suitable for agricultural programs where rapid dissolution and phosphorus availability are important considerations.
Total nitrogen plus phosphorus pentoxide content reaches ≥55%. The concentrated formulation helps agricultural distributors and growers deliver a significant amount of N and P₂O₅ without using excessive quantities of lower-analysis fertilizer.
The standard 2-4 mm granular specification provides good flowability and handling performance. Uniform particles are suitable for mechanical spreading, bulk fertilizer blending, packaging, and transportation.
Because of its high water solubility, the product can be considered for fertigation and water-based nutrient delivery systems when the fertilizer program and irrigation equipment are compatible.
MAP can be incorporated into compound fertilizer blends with compatible nitrogen, potassium, secondary, and micronutrient sources. Compatibility testing should be conducted before combining concentrated fertilizer materials.
The value of MAP depends on when phosphorus is needed, soil nutrient status, and the selected application method. It is generally positioned as a phosphorus-focused nitrogen fertilizer rather than a complete NPK fertilizer.
Applying MAP before or during planting can place readily available phosphorus close to the developing root zone. This is particularly useful for crops where early root establishment is a major management priority.
For crops requiring additional phosphorus during establishment, MAP can be incorporated into a starter fertilizer program. Application rates should be determined using soil test results and crop nutrient requirements.
The high water solubility allows MAP to be dissolved for fertigation applications. This approach enables nutrients to be delivered through irrigation systems during selected crop growth stages. Compatibility with irrigation water and other fertilizer products should be verified before application.
Fertilizer manufacturers can use MAP as a phosphorus-containing component when developing NPK or specialty fertilizer formulations. The 11-44 nutrient profile provides flexibility when adjusting nitrogen and phosphorus ratios.
| Crop Category | Typical Application Focus |
|---|---|
| Cereals | Early root development, seedling establishment, and phosphorus supplementation |
| Corn | Starter nutrition and early root-zone phosphorus supply |
| Rice | Basal fertilization and early crop establishment |
| Wheat | Root development and early-season nutrient management |
| Vegetables | Planting-stage phosphorus supply and root-zone nutrition |
| Peanuts and Cotton | Early growth and balanced nitrogen-phosphorus management |
| Fruit Trees | Phosphorus supplementation during selected growth stages |
| Application Method | Recommended Use | Key Consideration |
|---|---|---|
| Basal Application | Before planting or at planting | Place phosphorus within an appropriate root-zone area |
| Starter Fertilizer | Early crop establishment | Use according to soil phosphorus status and crop needs |
| Fertigation | Drip or irrigation-based nutrient delivery | Confirm dissolution and compatibility before mixing |
| Fertilizer Blending | NPK and specialty fertilizer production | Conduct compatibility testing with other raw materials |
Phosphorus behavior varies significantly between different soil types. Selecting a fertilizer only according to its total P₂O₅ value may therefore not provide enough information for an effective nutrient program.
In strongly acidic soils, phosphorus can interact with iron and aluminum compounds and become less available. Soil testing and appropriate soil management are important when designing a phosphorus fertilization program.
Near-neutral soils can provide favorable conditions for phosphorus management, although availability still depends on soil texture, organic matter, moisture, and existing nutrient levels.
In alkaline or calcareous soils, phosphorus can react with calcium and form less-soluble compounds. A water-soluble phosphate fertilizer can be useful where rapid phosphorus availability is required, but application placement and dosage remain important.

For fertilizer distributors and large agricultural buyers, consistency between shipments is an important purchasing consideration. AOLANSU therefore applies quality controls throughout the production process.
Raw materials are evaluated before entering production. Purity and relevant impurity indicators are controlled to reduce variations in the final fertilizer.
The reaction between phosphoric acid and ammonia is controlled according to process parameters such as feeding ratio, temperature, concentration, and reaction conditions. This helps maintain the required nitrogen-phosphorus composition.
The material is granulated and dried before screening. Oversized and undersized particles are separated to maintain the specified granular range and improve handling performance.
Each production batch is inspected for nitrogen, P₂O₅, water-soluble phosphorus, moisture, particle size, appearance, and other agreed quality indicators before shipment.
When purchasing MAP for commercial agricultural use, buyers should evaluate more than the nominal NPK number. The following factors can affect the actual suitability of a product for a fertilizer program.
Total P₂O₅ indicates the overall phosphorus content, while water-soluble phosphorus provides additional information about phosphorus availability. Both values should be reviewed when comparing suppliers.
Mechanical fertilizer spreaders and blending equipment may require specific particle-size distributions. The standard AOLANSU specification is 2-4 mm with ≥90% uniform particle rate.
Excessive moisture can contribute to caking during storage and transportation. The standard specification controls moisture at ≤2.0% and uses moisture-resistant export packaging.
For large-volume procurement, buyers can request a COA for each shipment to verify nutrient content and other agreed quality indicators before receiving the material.
In cotton production, phosphorus availability during early crop establishment can influence root development and crop uniformity. AOLANSU Agricultural Monoammonium Phosphate CAS 7722-76-1 can be incorporated into a basal fertilizer program where soil testing indicates a need for additional phosphorus.
For commercial farming, the actual application rate should be determined according to soil analysis, crop yield targets, existing nutrient levels, irrigation conditions, and local agronomic recommendations. This approach avoids applying excessive phosphorus while ensuring adequate nutrient availability during important growth stages.
AOLANSU provides packaging options designed for fertilizer distributors, commercial farms, and agricultural formulators.
Standard packaging includes 25 kg and 50 kg PP woven bags with PE inner liners. The inner liner provides additional protection against moisture during storage and international transportation.
