Phosphate Fertilizer

Browse by: All


    Urea phosphate, also known as urea phosphate or urea phosphate, is a ruminant feed additive that is superior to urea and can provide non-protein nitrogen and phosphorus at the same time. It is an organic matter with the chemical formula CO(NH2)2·H3PO4. It is easily soluble in water, and the aqueous solution becomes acidic; it is insoluble in ethers, toluene and carbon tetrachloride.


    MKP is a chemical with the chemical formula KH2PO4. Deliquescence. It melts into a transparent liquid when heated to 400°C, and solidifies into an opaque glassy potassium metaphosphate after cooling. Stable in the air, soluble in water, insoluble in ethanol. Industrially used as a buffer and culture agent; also used as a bacterial culture agent to synthesize a flavoring agent for sake, a raw material for making potassium metaphosphate, a culture agent, a strengthening agent, a leavening agent, and a fermentation aid for brewing yeast. In agriculture, it is used as a high-efficiency phosphate-potassium compound fertilizer.

    Diammonium phosphate, also known as diammonium hydrogen phosphate, diammonium phosphate, is a colorless transparent monoclinic crystal or white powder. The relative density is 1.619. Easily soluble in water, insoluble in alcohol, acetone, and ammonia. Decompose when heated to 155°C. When exposed to the air, it gradually loses ammonia and becomes ammonium dihydrogen phosphate. The aqueous solution is alkaline, and the pH value of 1% solution is 8. Reacts with ammonia to generate triammonium phosphate.
    The production process of diammonium phosphate: It is made by the action of ammonia and phosphoric acid.
    Uses of diammonium phosphate: used as a fire retardant for fertilizers, wood, paper, and fabrics, and also used in medicine, sugar, feed additives, yeast and other aspects.
    It gradually loses ammonia in the air and becomes ammonium dihydrogen phosphate. The water-soluble quick-acting fertilizer is used in various soils and various crops. It can be used as seed fertilizer, base fertilizer and top dressing. Do not mix it with alkaline fertilizers such as plant ash, lime nitrogen, lime, etc., so as not to reduce fertilizer efficiency.
