MONO AMMONIUM PHOSPHATE (MAP 12-61-0)
Molecular formula: NH4H2PO4
CAS Number:7722-76-1
As a fully water-soluble fertilizer, MAP is a highly efficient source of phosphorus and nitrogen for plants. It is recommended for use at the beginning of the growing season, because phosphorus availability is crucial for the establishment of root system at this stage. It can serve as a high quality source of phosphorus also during other stages of the growth cycle.
Its high purity and water-solubility make MAP an ideal fertilizer for fertigation and for foliar application. MAP is suitable for preparation of fertilizer blends and production of liquid fertilizers.
Main advantages
◆ Fully water-soluble;
◆ Consists of 100% plant nutrients;
◆ Highly-concentrated source of phosphorus for plants(61%P2O5/27%P);
◆ Free of chloride, sodium and other detrimental elements for plants;
◆ Moderately low pH(safer and less corrosive compared to urea phosphate);
◆ Suitable for the fertigation, foliar application and production of fertilizer blends and nutrient solutions;
◆ Not only that MAP is an efficient source of phosphorus, It also facilitates plant uptake of the phosphorus naturally present in the soil. This is due to the ammonium(NH4 +) in MAP, which lowers the pH in the root zone and thus enhances phosphorus availability.
Packing and Storage
Packing in 25kg, or big bags. Store at a cool, dry and well ventilated place.
