MAP (Mono-Ammonium Phosphate) – A High-Purity, Complete Phosphate Fertilizer
"MAP" is a pure, crystalline fertilizer known for its acidic reaction and complete water solubility. It is considered one of the best and most concentrated phosphate fertilizer options due to its high phosphorus content.
Nutrient Composition:
Element Percentage Nitrogen (NH₄-N) 12%
Available Phosphorus (P₂O₅) 61%
Soluble Potassium (K₂O) - (None)
Key Features:
1. Concentrated & Ideal Nutritional Formula:
- High Phosphorus Content: Contains a very high level of phosphorus (61%), which is essential for strong root development, stimulating flowering and fruit set, and playing a vital role in energy transfer within the plant.
- Balanced Ammonium Nitrogen: Provides 12% nitrogen in ammonium form, a plant-preferred form especially during early growth stages. It minimizes leaching losses and enhances absorption efficiency.
- Potassium-Free: This allows greater flexibility in fertilization programs, enabling growers to apply potassium separately and accurately according to crop needs at each growth stage.
2. High Solubility and Easy Application:
- Fully Water Soluble: Ensures complete dissolution in water, making it perfect for use in all modern irrigation systems (e.g., drip and center pivot), with no risk of clogging emitters or pipes—ensuring less maintenance and higher efficiency.
- Foliar Spray Friendly: Can also be effectively used as a foliar spray, delivering a quick dose of phosphorus and nitrogen—ideal for correcting deficiencies or supporting specific growth phases that require rapid nutrient availability.
3. Acidic Reaction for Enhanced Absorption:
- pH Reduction: MAP has an acidic effect when dissolved, helping to lower the pH of fertigation solutions and the root zone soil.
- Improved Nutrient Availability: This acidifying property enhances the availability and uptake of phosphorus and micronutrients (such as iron, zinc, and manganese), which are often locked in alkaline soils.
4. Safe to Use & Protects Equipment:
- Non-Corrosive to Skin: Unlike some other fertilizers, MAP is relatively safe to handle and does not cause skin burns—promoting safer field operations.
- Protects Irrigation Systems: Its formulation does not corrode metallic components of irrigation systems, contributing to longer equipment life and reduced maintenance costs over time.
5. High Flexibility in Fertilization Programs:
- Ideal for Early Growth Stages: An excellent choice during the initial stages of plant growth to support strong root development.
- Easy Mixing: Can be easily combined with most other fertilizers in compound fertigation programs (Caution: Avoid mixing with calcium-containing fertilizers to prevent precipitation).
