Magnesium Ammonium Phosphate Hexahydrate (MAPHE) is a premium water-soluble fertilizer that delivers essential nutrients—magnesium (Mg), ammonium nitrogen (NH₄), and phosphorus (P)—in a crystalline form. Its unique composition provides crops with a balanced supply of nutrients, promoting strong root growth, enhancing photosynthesis, and improving overall crop yield. Due to its excellent solubility, MAPHE is widely used in fertigation systems, direct soil application, and as a supplement to NPK fertilizer blends.
Magnesium Ammonium Phosphate Hexahydrate (MAPHE) is a high-efficiency fertilizer that combines magnesium, ammonium nitrogen, and phosphorus in a water-soluble form, making it highly effective in modern agricultural practices. This fertilizer is designed to meet the specific nutritional needs of crops, providing a balanced mix of macro-nutrients necessary for optimal growth and productivity.
MAPHE is derived from the combination of magnesium, ammonium nitrogen, and phosphorus in a stable crystalline form. This crystalline structure ensures the fertilizer is highly soluble in water, enabling rapid nutrient uptake by plants. The phosphorus content in MAPHE is especially beneficial for root development, promoting strong, healthy roots and improving the plant’s ability to absorb water and other nutrients. Magnesium, a vital nutrient for chlorophyll production, boosts photosynthetic efficiency and helps improve overall plant health. Ammonium nitrogen is a critical nutrient that supports plant growth, particularly during the vegetative phase.
MAPHE is versatile and can be applied in various ways, including soil application, fertigation, and foliar spraying. The high phosphorus content makes it particularly useful for crops in the flowering and fruit-setting stages, where phosphorus is crucial for energy transfer and reproductive growth. The magnesium ensures that crops maintain healthy chlorophyll levels and optimal photosynthetic activity, especially in high-light environments or during periods of rapid growth.
The slow-release properties of MAPHE make it an efficient fertilizer that minimizes nutrient leaching and runoff, ensuring that crops receive consistent nourishment over time. This also helps to improve soil fertility by promoting a balanced and sustainable nutrient cycle. MAPHE is also compatible with a wide range of other fertilizers and is ideal for use in combination with NPK fertilizers to achieve a more comprehensive nutrient profile.

Application
MAPHE can be applied in several different ways, depending on the specific needs of the crops being grown and the farming practices employed:
● Soil Application: MAPHE can be applied directly to the soil before planting or as a top dressing during the growing season. When applied to the soil, MAPHE provides a steady release of essential nutrients, ensuring that crops receive a balanced supply of magnesium, phosphorus, and ammonium nitrogen for healthy root growth and strong plant development.
● Fertigation: MAPHE’s excellent water solubility makes it particularly effective for use in fertigation systems. It can be applied through drip irrigation or sprinkler systems, allowing nutrients to be delivered directly to the plant’s root zone. This method ensures efficient nutrient uptake and is especially effective in large-scale agricultural operations.
● Foliar Application: MAPHE can be dissolved in water and applied as a foliar spray, providing an immediate nutrient boost to crops. This is especially useful during critical growth stages such as flowering, fruit setting, or during stress conditions where plants may need a rapid supply of nutrients.
Benefits
MAPHE offers numerous benefits that contribute to improved plant health and increased crop productivity:
● Balanced Nutrient Supply: MAPHE provides a balanced mix of magnesium, phosphorus, and ammonium nitrogen, which are essential for robust plant growth, enhanced root development, and overall plant vitality. These nutrients are delivered in a form that is highly accessible to plants, ensuring efficient uptake.
● Improved Root and Plant Development: The high phosphorus content in MAPHE is crucial for strong root systems, while the magnesium ensures that plants can carry out efficient photosynthesis. Together, these elements support strong, healthy plants with better growth potential.
● Efficient Nutrient Use: MAPHE’s excellent solubility ensures that nutrients are available to plants quickly, enhancing nutrient absorption. Its slow-release characteristics reduce nutrient leaching and runoff, making it an environmentally friendly choice that improves nutrient utilization efficiency.
● Enhanced Crop Yield and Quality: By promoting healthier root systems and stronger plant structures, MAPHE contributes to improved crop yields and better-quality produce. The magnesium also helps plants withstand environmental stress, improving their resilience to factors like drought, high temperatures, and nutrient deficiencies.
● Compatibility with Other Fertilizers: MAPHE is highly compatible with most NPK blends and other fertilizers, making it easy to integrate into existing fertilization programs. This allows farmers to customize their fertilization plans based on the specific needs of their crops.
Environmental Impact
MAPHE is an environmentally responsible fertilizer. Its slow-release properties minimize the risk of nutrient leaching, reducing the potential for water pollution and nutrient runoff. By promoting more efficient nutrient cycling, MAPHE helps maintain a balanced and sustainable soil ecosystem. Its use also supports sustainable farming practices by reducing the need for excessive chemical inputs.
Conclusion
Magnesium Ammonium Phosphate Hexahydrate (MAPHE) is a highly efficient and versatile fertilizer that provides essential nutrients for healthy plant growth. With its high solubility, balanced nutrient profile, and environmentally friendly characteristics, MAPHE has become a popular choice among farmers looking to improve soil fertility, enhance crop productivity, and support sustainable agriculture. Whether used in soil applications, fertigation systems, or foliar sprays, MAPHE helps ensure that crops receive the nutrients they need at critical growth stages, leading to healthier plants, higher yields, and better-quality produce.
