FAQ
What are the effects of ammonium dihydrogen phosphate on plants?
It is a high-concentration binary compound fertilizer used as topdressing. With over 61% phosphorus content, it is safer (no sodium/calcium) and highly effective. It promotes root growth, improves plant resistance, and is suitable for all crops during seedling stages.
What role does ammonium dihydrogen phosphate play in industry?
It acts as a flame retardant for wood, paper, and fabric. It's also used as a dispersant in the dye industry, an admixture for fire retardant coatings, and a dry powder fire extinguishing agent.
Is Monoammonium Phosphate (MAP) fully water-soluble?
Yes, MAP has excellent water solubility. At a normal temperature of 20ºC, its solubility is approximately 37.4g per 100ml of water, making it ideal for fertigation and drip irrigation systems.
What are the recommended storage conditions?
MAP should be stored in a cool, dry place. Ensure bags are sealed to prevent moisture absorption. Protect the product from direct sunlight and water to maintain its crystalline quality.
What purity levels are available for MAP?
Our technical grade Monoammonium Phosphate features a high purity level of ≥99.5%, ensuring minimal impurities and optimal performance for both agricultural and industrial applications.
What packaging options do you offer for transport?
The standard transport packages include 25kg, 50kg, and 1000kg (Jumbo) woven bags lined with plastic film to ensure the product remains dry and intact during shipping.
