Mono Ammonium Phosphate 12-61-0
MAP has been an important granular fertilizer for many years. It’s water-soluble and dissolves rapidly in adequately moist soil. Upon dissolution, the two basic components of the fertilizer separate again to release ammonium (NH₄⁺) and phosphate (H₂PO₄⁻), both of which plants rely on for healthy, sustained growth. The pH of the solution surrounding the granule is moderately acidic, making MAP an especially desirable fertilizer in neutral and high-pH soils.
Growers apply granular MAP in concentrated bands beneath the soil surface in proximity of growing roots or in surface bands. It’s also commonly applied by spreading it across the field and mixing it into the surface soil via tillage. In powdered form, it’s an important component of suspension fertilizers. When MAP is made with especially pure H₃PO₄, it readily dissolves into a clear solution dispersed as a foliar spray or added to irrigation water. The P₂O₅ equivalent content of high-purity MAP is usually 61 percent. Chemical Properties.
Chemical Formula: NH4H2PO4
P2O2 range: 48 to 61%
N range: 10 to 12%
Water Solubility: (200) 370g/L
Solution pH: 4 to 4.5 Management practices
No special precautions are needed with the use of MAP. The slight acidity associated with this fertilizer reduces the potential for NH₃ loss to the air. MAP can be placed in close proximity to germinating seeds without concern for NH₃ damage. However, MAP used in foliar spray or added to irrigation water, shouldn’t be mixed with calcium or magnesium fertilizers.
A high purity source of MAP is used as a feed ingredient for animals. The NH₄⁺ is synthesized into protein and the H₂PO₄⁻ supports a variety of metabolic functions in animals. Characteristics of Mono Ammonium phosphate 12.61.0 imported from Down Crop UK
Fully water-soluble 1- Consists of 100% plant nutrients 2- Highly-concentrated source of phosphorus for plants (61% P2O5 / 27% P) 3- Free of chloride, sodium and other detrimental elements for plants 4- Moderately low pH (safer and less corrosive compared to urea phosphate) 5- Suitable for Fertigation ,foliar application and production of fertilizer blends and nutrient solutions
MAP 12.61 is a pure residue-free fully hydrosoluble monoammonium phosphate (12-61-0).
Both Nitrogen and Phosphorus contained in MAP 12.61 are easily absorbed by plants.
MAP should be used at the early stage of plant development, when plants require large amounts of Phosphorus in order to stimulate root growth and, during the flowering phase, the fertilization of flowers.
MAP can be mixed with other fertilizers to provide crops with the nutrients needed during the whole plant growth cycle. Do not mix the concentrated solution with Calcium-based and Magnesium fertilizers. Benefit:
As a highly efficient source of phosphorus and nitrogen for plants, AK Industry with the collaboration of DOW CROP UK recommended for use at the beginning of the growth season, when phosphorus availability is crucial for the establishment of the root system.
• Fully hydrosoluble, no precipitation;
• Low Chlorine and sodium content;
• Free of heavy metals;
• Suitable for nutrient solutions;
• Acidic pH;
• Boosted root growth;
• Enhanced crop flowering.
• Mono ammonium phosphate is appropriate for fertilization of all soils and crops. Because of the fact that it is water-soluble, it has the properties of fast-acting phosphorus fertilizer, and the low mobility of the phosphorus in the soil allows its use for main, stocking as well as for periodic fertilization.
• This fertilizer is input with the main treatment of the soil or prior to sowing. It is also used in main and pre-sowing fertilization of all field vegetables, fruit crops, grape vines, herbs and flowers.
• It is stored in covered, cold and dry storehouse premises. Heating and mixing with water is not desirable. It is transported packaged or in bulk. AK Industry Berry International offers mono ammonium phosphate in packages of ( bags of 25kg)
