Specifications
- Chemical Composition:
Mono Ammonium Phosphate is a compound fertilizer with the chemical formula
NH₄H₂PO₄. It typically contains 11-12% nitrogen (N) and 48-50% phosphorus
(P₂O₅).
- Form:
MAP is usually available in granular form, which makes it easy to handle,
apply, and incorporate into the soil.
- Texture:
The granules are generally uniform in size, ranging from 1 to 4 mm in
diameter. The texture is fine and dry, which helps in even application.
- Moisture Content:
MAP has a very low moisture content, making it stable and resistant to
clumping or caking.
- pH Level:
MAP is slightly acidic, with a pH around 4.0 to 5.0 when dissolved in
water. This can help in lowering soil pH in alkaline soils.
Benefits
- Enhanced Phosphorus Supply: Provides a high concentration of phosphorus, which is
essential for root development, energy transfer, and flowering. This helps
in establishing strong root systems and improving plant vigor.
- Balanced Nutrient Supply: Delivers both nitrogen and phosphorus in one
application, supporting overall plant growth and development. Nitrogen
promotes leafy growth, while phosphorus supports root and flower
development.
- Improved Crop Yields:
By providing a readily available source of phosphorus, MAP can enhance
crop yields and improve the quality of fruits, vegetables, and grains.
- Soil Fertility:
Helps in improving soil fertility by increasing phosphorus levels, which
can be a limiting nutrient in many soils.
- Efficient Nutrient Uptake: Granular form allows for uniform application and
efficient nutrient uptake by plants. The phosphorus in MAP is readily
available to plants, even in soils with high pH levels.
- Reduced Leaching:
MAP’s composition helps to reduce nutrient leaching compared to some other
phosphorus fertilizers, ensuring that nutrients are available for longer
periods.
Dose
- General Application:
The typical application rate of MAP depends on soil tests and crop
requirements. A common recommendation is to apply 100-200 kg of MAP per
hectare before planting. This can vary based on soil nutrient levels and
specific crop needs.
- Row Crops:
For crops such as corn, soybeans, or wheat, apply 20-50 kg of MAP per
hectare at planting time. This should be incorporated into the soil to
ensure effective nutrient uptake.
- Vegetable and Flower Gardens: Use about 1-2 pounds of MAP per 100 square feet of
garden area. Apply it to the soil before planting and incorporate it
thoroughly.
- Fruit Trees:
Apply 1-2 pounds of MAP per tree, spreading it evenly around the root
zone. Incorporate it into the soil if possible.
- Potted Plants:
Mix 1-2 tablespoons of MAP into each gallon of potting soil before
planting. For top-dressing, apply a small amount evenly around the base of
the plant.
- Lawns:
Apply 0.5-1 pound of MAP per 1,000 square feet of lawn area. This can be
applied in early spring or late fall, depending on lawn needs.
In summary, Mono Ammonium Phosphate
is a highly effective fertilizer that supplies essential nutrients for plant
growth, with a particular focus on phosphorus and nitrogen. Its use in various
agricultural and gardening applications helps to improve soil fertility,
enhance crop yields, and support healthy plant development. By following
recommended dosages and application methods, users can optimize the benefits of
MAP for their specific needs.
