Diammonium phosphate (DAP) is a widely used fertilizer that provides a high concentration of phosphorus and nitrogen nutrients. It is composed of two ammonium ions and one phosphate ion. DAP is a water-soluble salt and is often used in agricultural settings to enhance plant growth. Here are some key points about diammonium phosphate: The nitrogen in DAP is readily available for plants, while phosphorus is essential for root development, flowering, and fruiting. Solubility: Diammonium phosphate is highly water-soluble, making it easy to apply as a liquid fertilizer or to dissolve in irrigation systems. pH and Acidity: DAP tends to be slightly acidic, which can contribute to lowering the pH of the soil over time. It is essential to monitor soil pH when using fertilizers to prevent overly acidic conditions. Application: DAP is commonly used as a dry granular fertilizer that can be broadcast on the soil surface. It can also be dissolved in water and applied as a liquid fertilizer through irrigation systems, providing quick nutrient availability to plants. Uses: Diammonium phosphate is suitable for a variety of crops, including grains, fruits, vegetables, and legumes. It is often used during the early stages of plant growth to promote root development. Storage: DAP should be stored in a cool, dry place to prevent moisture absorption and caking. Safety Considerations: When handling DAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation. Compatibility: Diammonium phosphate is compatible with many other fertilizers and can be used in combination with them to provide a broader spectrum of nutrients. Environmental Impact: Like other fertilizers, the application of DAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.
Diammonium phosphate, also known as diammonium hydrogen phosphate (DAP), is a compound fertilizer containing nitrogen and phosphorus. DAP is a high-efficiency fertilizer widely used in vegetables, fruits, rice and wheat. It is also used in animal feed, food, printing and plate making, medicine, fire prevention, electronic tubes and other industries. Diammonium phosphate, also known as diammonium hydrogen phosphate (DAP), is a compound fertilizer containing two nutrients, nitrogen and phosphorus. 1,Diammonium phosphate is a high-concentration nitrogen and phosphorus compound fertilizer based on phosphorus, which is suitable for the vast majority of crops and is also suitable for use in various soils. It can be used in a wide range of fields and can be used as base fertilizer or topdressing. 2,Diammonium phosphate can be used to fertilize a variety of soil types in paddy field and dry land, suitable for rice, wheat, corn, sweet potato, peanut, rape, peanut and other crops, especially for sugarcane, water chestnuts and other hydrogen-loving and phosphorous crops. 3,Diammonium phosphate can be combined with ammonium bicarbonate, urea, ammonium chloride, potassium chloride, ammonium nitrate and other fertilizers, avoid mixed application with ammonium sulfate and calcium superphosphate and other acidic fertilizers, the effect is better after use, and promote the growth of plants.

DAP is the most widely used phosphate fertilizer among growers today. It is manufactured by reacting phosphoric acid and ammonia and contains two ammonia molecules. In alkaline soil conditions, one of the ammonia molecules in DAP will revert to ammonia, making it an excellent fit for low pH or alkaline soil. DAP itself is alkaline with a high pH, exceeding 7.5. Nutrients include P2O5 (46%) and ammoniacal nitrogen (18%). DAP provides the correct proportion of phosphate and nitrogen needed for farming wheat, barley and vegetables. It is also applied in the early stage of fruit orchard fertilization.

Diammonium phosphate (DAP) (chemical formula (NH4)2HPO4, IUPAC name diammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation:[2] (NH4)2HPO4(s) NH3(g) + NH4H2PO4(s) log PmmHg = 3063 / T + 175 log T + 3.3 where: P = the resultant dissociation pressure of ammonia T = absolute temperature (K) At 100 C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg.[3] Accordingly, to MSDS of DiammoniumPhosphate from CF Industries inc. decomposition starts as low as 70*C "Hazardous Decomposition Products: Gradually loses ammonia when exposed to air at room temperature. Decomposes to ammonia and monoammonium phosphate at around 70�°C (158�°F). At 155�°C (311�°F), DAP emits phosphorus oxides, nitrogen oxides and ammonia." Uses DAP is used as a fertilizer.[4] When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.5â??8.[5] The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).[5] DAP can be used as a fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.[6] These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of available fuel and can lead to the formation of a firebreak. It is the largest component of some popular commercial firefighting products.[7] DAP is also used as a yeast nutrient in winemaking and mead-making; as an additive in some brands of cigarettes purportedly as a nicotine enhancer; to prevent afterglow in matches, in purifying sugar; as a flux for soldering tin, copper, zinc and brass; and to control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.[1] Specification of Diammonium Phosphate P2O5 44-48 % N2 18-19.5 % H2O 1.5 Max % PARTICLE SIZE 1-4 mm 85% Min DENSITY 0.92-0.98 gr/cc
