Our Agricultural MAP features a total nutrient content (N + P₂O₅) of ≥55% and a nitrogen-to-phosphorus ratio of 1:4, with water-soluble phosphorus accounting for ≥90%. It is suitable for a wide variety of crops and soil types, offering both high nutrient utilization efficiency and strong stability. As a professional supplier, we offer direct-from-factory pricing, flexible packaging options, and comprehensive export services to assist growers worldwide in achieving increased yields and improved crop quality.
1. Raw Material Selection
Our Agricultural MAP is produced using high-purity phosphoric acid and liquid ammonia as raw materials. Every batch of raw materials undergoes rigorous purity testing prior to entering the facility to ensure that impurities do not compromise fertilizer efficacy.
2. Process Control
We utilize an integrated production line encompassing chemical synthesis, granulation, drying, and packaging. Specialized technical personnel supervise the entire process to ensure uniform granule size and optimal moisture content.
3. Quality Standards
The finished product complies with international procurement specifications. With a water-soluble phosphorus content of ≥90%, the nutrients are rapidly absorbed by crop root systems, thereby minimizing nutrient loss. Furthermore, the product exhibits strong stability, resisting caking during long-distance transport and prolonged storage.
1. Scientific Nutrient Ratio: Precise and Efficient Fertilization
The nitrogen-to-phosphorus ratio of 1:4 is precisely tailored to meet the specific nutrient requirements of crops during their seedling, flowering, and fruit-setting stages. This promotes robust root development, strengthens seedlings, and enhances their resistance to environmental stressors—specifically improving drought and cold tolerance. Compared to traditional phosphorus fertilizers, our product features a higher content of water-soluble phosphorus and a faster absorption rate, resulting in a significantly higher fertilizer utilization efficiency.
2. Broad Applicability
- Crop Suitability: Suitable for a wide range of crops, including staple grains (rice, wheat, corn), cash crops (cotton, peanuts, vegetables), and fruit trees (apples, citrus, grapes).
- Soil Suitability: Effective in acidic, neutral, and slightly alkaline soils. It can also serve to ameliorate acidic soils, alleviate soil compaction, and enhance overall soil fertility. - Application Methods: Suitable for use as both a basal fertilizer and a top dressing; supports broadcasting, spot application, and furrow application; compatible with both mechanical sowing and manual fertilization.
3. Stable Physical Properties: Convenient for Storage and Transport
Agricultural MAP features uniform granules (2–4 mm) with excellent flowability; it resists caking, is moisture-proof, and is abrasion-resistant. These properties make it ideal for long-distance transport and long-term storage, thereby minimizing the risk of product loss.
Case 1: Cotton Cultivation in Xinjiang, China (Alkaline Soil)
Ms. Wang, a farmer in the 127th Regiment of Xinjiang, cultivates cotton on saline-alkali land (pH > 7.5). Previously, she used traditional Diammonium Phosphate (DAP); this resulted in yellowing leaves and stunted root growth during the seedling stage, incurring a replanting cost of approximately 200 RMB per mu. In 2024, she switched to using AOLANSU Agricultural MAP as a basal fertilizer (25 kg per mu), applied in conjunction with humic acid. The result was uniform seedling emergence and robust root systems, with zero instances of yellowing or stunted growth. Consequently, replanting costs dropped to zero, yield per mu increased by 12%, and the crop's drought resistance was significantly enhanced.
Case 2: Rice Cultivation in Southeast Asia (Acidic Soil)
In the Mekong Delta rice-growing region of Vietnam, the soil pH is 5.2 (acidic). Long-term rice cultivation in this environment often leads to phosphorus deficiency and premature senescence (early aging) of the crop. In 2024, local growers adopted AOLANSU MAP as a basal fertilizer (30 kg per mu), supplemented by a single top dressing during the tillering stage. This approach fostered well-developed root systems and prolific tillering in the rice plants. By the maturation stage, the rate of premature senescence had decreased by 20%, the thousand-grain weight increased, and the yield per mu rose by 10% compared to traditional fertilizers; furthermore, the trend of soil acidification was effectively mitigated.
