Our MAP is recommended for use at the beginning of the growth season, when phosphorus availability is crucial for the establishment of root system. MAP can be tank-mixed with other fertilizers to meet crops' nutritional needs throughout the growth cycle. Its color is crystal white. Its relative density is 1.803g/cm3, and the melting point is at 180°C, stable in air, partly decomposed at the temperature of 100°C. It is easily soluble in water, slightly soluble in alcohol, insoluble in ketone. Its PH value of 1% solution is 4.5. Its total nourishment (N+P2O5) is at 73%, free of chloride, sodium and other detrimental elements for plants.
It can also be used for the production of nutrient solutions and as a basic raw material for N, P and K compound fertilizers.
