AOLANSU Agricultural MAP (Monoammonium Phosphate) is a high-efficiency phosphorus and nitrogen fertilizer designed for modern crop cultivation. With a nutrient combination of nitrogen (N) and phosphorus pentoxide (P₂O₅), it provides a rapid nutrient supply during critical crop growth stages, especially during root development, seedling establishment, flowering, and fruit setting.
Manufactured in China through a controlled ammoniation process using selected phosphoric acid and ammonia, AOLANSU Agricultural MAP features high water-soluble phosphorus availability, uniform granules, and excellent storage stability. It is widely used by agricultural distributors, commercial farms, and fertilizer formulators in different regions worldwide.
The production of Agricultural MAP starts with carefully selected phosphoric acid and ammonia. Each batch of raw material is inspected before production, including purity analysis and impurity detection, ensuring stable nutrient performance and consistent fertilizer quality.
Through ammoniation reaction, granulation, drying, screening, and surface treatment processes, the fertilizer is manufactured into uniform particles with good mechanical strength. The controlled particle size improves handling efficiency during mechanical fertilization and long-distance transportation.
Every production batch is tested for nutrient content, moisture level, particle distribution, and water solubility. The finished product maintains a total nutrient content of N + P₂O₅ ≥55%, with water-soluble phosphorus ≥90%, ensuring fast nutrient availability after application.
Phosphorus plays an essential role in root formation, energy transfer, and crop maturity. AOLANSU Agricultural MAP provides highly available phosphorus that can be quickly dissolved and absorbed by plant roots, helping crops establish stronger root systems and improving nutrient uptake efficiency during early growth stages.
Compared with traditional phosphate fertilizers with lower water-soluble phosphorus content, this product reduces nutrient fixation in soil and improves phosphorus utilization, especially in intensive farming systems where rapid nutrient response is required.
The combination of approximately 11% nitrogen and 44% available phosphorus creates an effective nutrient ratio for crops requiring strong root development and early-stage growth support.
It is particularly suitable for crops that require additional phosphorus during establishment periods, including rice, wheat, corn, cotton, vegetables, and fruit trees.
Agricultural MAP can be applied in acidic, neutral, and slightly alkaline soils. Due to its weakly acidic characteristics, it can help improve phosphorus availability in certain soil environments where phosphorus becomes easily fixed.
For regions with different soil conditions, application rates can be adjusted according to soil testing results, crop variety, and local cultivation practices.
For rice, wheat, and corn cultivation, Agricultural MAP is commonly used as a base fertilizer before sowing. It supports early root growth and improves seedling establishment.
For cotton, peanuts, vegetables, and other commercial crops, it can be applied during planting preparation or early growth stages to promote stronger root systems and improve crop uniformity.
For orchards such as citrus, grapes, and apples, Agricultural MAP can be combined with other fertilizers during flowering and fruit-setting periods to support fruit development and nutrient accumulation.
A cotton-growing farm located in Xinjiang faced challenges caused by alkaline soil conditions and insufficient phosphorus availability during early plant development. After replacing conventional phosphate fertilizer with AOLANSU Agricultural MAP as a basal fertilizer, the farm observed more uniform seedling emergence and stronger root growth.
The application program included 25 kg of Agricultural MAP per mu combined with soil improvement practices. During the growing season, farmers reported improved crop establishment, reduced weak seedlings, and more consistent field performance compared with previous fertilization methods.
This practical application demonstrates that selecting a suitable phosphorus fertilizer according to soil conditions can significantly improve nutrient efficiency and crop management results.

A1: Agricultural MAP and DAP both provide nitrogen and phosphorus, but they have different nitrogen-phosphorus ratios and soil adaptability. MAP contains less nitrogen and provides a higher proportion of phosphorus, making it especially suitable for crops requiring strong root development during early growth stages. Its weakly acidic property also makes it suitable for many soil conditions where phosphorus availability needs improvement.
A2: Yes. Due to its high water solubility and low impurity content, Agricultural MAP can be dissolved in water and applied through fertigation systems. Before large-scale use, it is recommended to confirm compatibility with other fertilizers to avoid precipitation caused by mixing different formulations.
A3: Agricultural MAP is widely used for cereals, vegetables, fruit trees, and commercial crops. It is especially beneficial during stages requiring phosphorus support, including seed germination, root establishment, flowering, and early fruit development.
A4: The application method depends on crop type, soil fertility, and farming practices:
- Base Fertilizer: Apply before planting and mix evenly with soil to support early root growth.
- Top Dressing: Apply during early growth stages when crops require additional phosphorus and nitrogen.
- Fertigation: Dissolve in water for precise nutrient delivery in modern irrigation systems.
A5: Yes. AOLANSU provides product samples for testing, along with commonly required export documents including COA, MSDS, and Certificate of Origin. Our technical team can also provide application suggestions based on crop type and destination market requirements.
