Product Description
Product Description
MAP Supplier UAE |At Agro National Chemical Fertilizer Trading, we understand the challenges of farming in high-pH (alkaline) soils common in the Middle East and arid regions. MAP 11:52 is the technical solution to these challenges.
Unlike DAP, which has an alkaline reaction, MAP creates a temporary acidic zone around the granule upon dissolution. This acidity neutralizes free lime in the soil and improves the uptake of not just phosphorus, but also immobile micronutrients like Zinc, Iron, and Manganese.
Why Choose Agro National for MAP 11:52?
-
Highest P-Content: Containing 52% P2O5, it minimizes logistics costs per unit of nutrient delivered.
-
Enhanced Uptake: The acidic pH (approx. 4.0-4.5) in the granule micro-site prevents phosphorus lock-up in calcareous soils.
-
Crop Safety: Lower ammonia toxicity potential compared to DAP, making it safer for seed-placed application (starter fertilizer).
-
Versatility: Ideal for direct application, bulk blending (NPK mixing), and use in fertigation (if soluble grade is specified).

Applications & Usage
-
Starter Fertilizer:
Excellent for placement with seeds during planting due to low salt index and lack of free ammonia toxicity.
-
Alkaline/Calcareous Soils:
The preferred phosphate source for high-pH soils. The acidification helps release calcium-bound phosphorus.
-
Bulk Blending:
Compatible with most other fertilizers (Urea, Potash) for creating custom NPK blends. (Note: Avoid mixing with Lime or Calcium Nitrate).
