MAP 10-50 Fertilizer (Monoammonium Phosphate 10-50)

MAP10-50 Fertilizer (Monoammonium Phosphate 10-50) is a high-concentration nitrogen and phosphorus compound fertilizer. With a phosphorus content of 50%, it far exceeds that of ordinary compound fertilizers. It usually exists as white or light gray crystals or powder. Our product is in powder form and ensures 100% water solubility. It is widely used during the critical periods of strengthening root systems and promoting flowering and fruiting, and is a core fertilizer for precisely supplementing phosphorus in agricultural production.

Product advantages

1. The product is a fully water-soluble powder structure, with phosphorus existing in the form of phosphate ions, which can be directly absorbed by crops. Compared with ordinary phosphate fertilizers, it has stronger mobility in the soil and can reach the root absorption zone more quickly. Even in environments that are unfavorable for phosphorus activation, such as low temperatures and alkaline soils, it still maintains an absorption and utilization rate of over 80%.

2. Compared to single potassium dihydrogen phosphate, the 10-50 nitrogen-phosphorus ratio is more suitable for long-term phosphorus supplementation, avoiding the nitrogen imbalance caused by sole phosphorus supplementation, and there is no need to add additional nitrogen fertilizers.

3. Produced from high-quality phosphate rock resources, it contains no chloride ions, heavy metals or other impurities, and has a slightly acidic pH value, which is non-irritating to crop roots.

Product Applications

1.Mixed application of base fertilizer: Before sowing or transplanting, apply 20-30 kilograms per mu, and use it in combination with well-rotted organic fertilizer to reserve phosphorus for the entire growth period of the crop.

2.Hole application at the seedling stage: Make shallow holes near the root system of the seedlings. Apply 5-10g per plant, cover with soil and water. This enables the seedlings to establish their absorption system more quickly.

3. Emergency foliar spray: When crops show symptoms of phosphorus deficiency (purple leaves and slow growth), apply a 500-800 times diluted solution by foliar spray. Symptoms can be relieved within 3-5 days, buying time for subsequent phosphorus supplementation through the root system.

Notes to Observe

It should not be applied simultaneously with alkaline substances such as wood ash or lime, as this will reduce its effectiveness. The single application per mu should not exceed 30 kilograms, and the interval between applications should be no less than 20 days. It should be stored in a dry and well-ventilated warehouse, avoiding open-air stacking to prevent moisture absorption and caking, which may affect its solubility.
