White transparent crystals, fully water-soluble and rapidly absorbed by crops; stable in air and non-caking, pH 4.4-4.8 as a 1% solution. Supplies both water-soluble phosphorus and ammonium nitrogen, promoting root development during the growing stage. Harmless to crops and suitable for foliar spray, drip and furrow application, especially for chloride-sensitive crops and calcareous or high-salinity soils. Its high purity and solubility prevent drip-system clogging, and it is a major N and P source for compound fertilizer formulations.
