DIAMMONIUM PHOSPHATE

CAS NO:7783-28-0
EC NO:231-987-8

Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH4)2(HPO4) 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:

(NH4)2HPO4(s) ⇌ NH3(g) + (NH4)H2PO4(s)
At 100 °C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg.

According to the diammonium phosphate MSDS 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
Diammonium phosphate is used as a fertilizer. 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.
Diammonium phosphate 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 7.5–8. The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).

Diammonium phosphate can be used as a fire retardant.
Diammonium phosphate lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char. 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.
Diammonium phosphate is the largest component of some popular commercial firefighting products and is the ingredient in "fire retardant" cigarettes.

Diammonium phosphate 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.

Diammonium phosphate (DAP) is the world’s most widely used phosphorus (P) fertilizer. It is made from two common
constituents in the fertilizer industry and it is popular because of its relatively high nutrient content and its excellent
physical properties.

Production
Ammonium phosphate fertilizers first became available in the 1960s and Diammonium phosphate rapidly became the most popular in this class of products.
Diammonium phosphate is formulated in a controlled reaction of phosphoric acid with ammonia, where the hot slurry is then cooled, granulated, and sieved.
Diammonium phosphate has excellent handling and storage properties. The standard grade of Diammonium phosphate is 18-46-0 and fertilizer products with a lower nutrient content may not be labeled as Diammonium phosphate. The inputs required to produce one ton of Diammonium phosphate fertilizer are approximately 1.5 to 2 tons of phosphate rock, 0.4 tons of sulfur (S), to dissolve the rock, and 0.2 tons of ammonia. Changes in the supply or price of any of these inputs will impact
Diammonium phosphate prices and availability. The high nutrient content of DAP is helpful in reducing handling, freight, and application costs.
Diammonium phosphate is produced in many locations in the world and is a widely traded fertilizer commodity.

Chemical Properties
Chemical formula: (NH4)2HPO4
Composition: 18% N
46% P2O5 (20% P)
Water solubility (20 ºC): 588 g/L
Solution pH: 7.5 to 8

Agricultural Use
Diammonium phosphate fertilizer is an excellent source of P and nitrogen (N) for plant nutrition.
Diammonium phosphate is highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of Diammonium phosphate is the alkaline pH that develops around the dissolving granule. As ammonium is released from dissolving Diammonium phosphate granules, volatile ammonia can be harmful to seedlings and plant roots in immediate proximity. This potential damage is more common when the soil pH is greater than 7, a condition that commonly exists around the dissolving Diammonium phosphate granule. To prevent the possibility of seedling damage, care should be taken to avoid placing high concentrations of Diammonium phosphate near germinating seeds.

The ammonium present in Diammonium phosphate is an excellent N source and will be gradually converted to nitrate by soil bacteria, resulting in a subsequent drop in pH. Therefore, the rise in soil pH surrounding Diammonium phosphate granules is a temporary effect. This initial rise in soil pH neighboring Diammonium phosphate can influence the micro-site reactions of phosphate and soil organic matter.

Diammonium phosphate (DAP) is the world’s most widely used phosphorus fertilizer.
Diammonium phosphate’s made from two common constituents in the fertilizer industry, and its relatively high nutrient content and excellent physical properties make it a popular choice in farming and other industries.

Diammonium phosphate also acts as a fire retardant. For example, a mixture of Diammonium phosphate and other ingredients can be spread in advance of a fire to prevent a forest from burning.
Diammonium phosphate then becomes a nutrient source after the danger of fire has passed.
Diammonium phosphate is used in various industrial processes, too, such as metal finishing. And, it’s commonly added to wine to sustain yeast fermentation and to milk to produce cheese cultures.

Most concentrated phosphate-based fertilizer.
Diammonium phosphate is perfect for any agriculture crop to provide full phosphorus nutrition throughout crop growth and development, as well as a starter dose of nitrogen and low sulphur.

Diammonium phosphate can be applied in autumn for tilling and in spring during sowing, as well as for pre-sowing cultivation. Dissolving in soil, it provides temporary alkalization of pH of the soil solution around the fertilizer granule, thus stimulating better uptake of phosphorus from the fertilizers on acid soils. Fertilizer’s sulphur also contributes to the better intake of nitrogen and phosphorus by plants.

Diammonium phosphate is an inorganic phosphate, being the diammonium salt of phosphoric acid. The commercially available fertilizer has an analysis of 18-46-0 (N-P2O5-K2O) and is marketed under the name diammonium phosphate or DAP.
Diammonium phosphate has a role as a fertilizer.

Diammonium phosphate [(NH4)2HPO4] is the world's most commonly used phosphorus fertilizer by growers today.
Diammonium phosphate is made from two common macronutrients (phosphate and nitrogen at 18N–46P2O5–0K2O content) and it is popular because of its relatively highest concentration of phosphate and nitrogen content coupled with its excellent physical properties.

DAP (Diammonium Phosphate) fertilizer has a composition of 18% N, 46% P2O5 and is a two-nutrient compound fertilizer. In addition to being used as a source of phosphorus fertilizer, the nitrogen in its content is in the form of ammonium (NH4 +), so it is easily retained in the soil and there is no nitrogen loss by washing from the soil due to excessive rainfall or irrigation.
Diammonium phosphate plays an important role in root development and energy metabolism especially in the first development period of plants.
Diammonium phosphate is efficient in terms of solubility and vegetative nutrition and is used as the most preferred underground (base) fertilizer by farmers.
Diammonium phosphate fertilizer, like all base fertilizers, can be used before sowing or with sowing.
Diammonium phosphate should be applied and mixed into the soil. Since the phosphorus contained in DAP fertilizer is kept in the soil and cannot move to the depths of the soil, its application after germination does not show its effect.

Diammonium phosphate popularly known as DAP is a preferred fertilizer in India because it contains both Nitrogen and Phosphorus which are primary macro-nutrients and part of 18 essential plant nutrients.

Soil Testing: For efficient use of this fertilizer, soil must be tested for nitrogen and phosphorus content in order to determine the required amount of Diammonium phosphate.

Basal Dose: Diammonium phosphate is the best suited fertilizer for basal dose as through this we can apply full dose of phosphorus and one-third to half dose of nitrogen. Remaining dosage of nitrogen can be applied through splits of urea at other stages of crop . So Diammonium phosphate gives the best combination with urea fertilizer.
Diammonium phosphate is also the best fertilizer for pulses where less nitrogen and higher phosphorus is needed as starter dose.

Placement of Diammonium phosphate: Since phosphorus is immobile in soil, its source (DAP) should be placed at a distance where plant roots can easily reach. Improper application of DAP may cause seedling injury due to release of ammonia.
Diammonium phosphate should be placed below seed, slightly to one side.

Soil Amendments: Nitrogen as well as phosphorus, give best results in neutral soils. But in case of alkaline, volatilization losses of ammonia are higher. So nitrogen use efficiency is reduced. Similarly excessive presence of calcium in alkaline soils, makes complexes with phosphorus and ultimately results in poor phosphorus recovery. So bringing soil pH to neutral by adding gypsum and leaching can only improve N and P use efficiency of DAP.
In acidic soils, problem ions like Fe, AI and Mn become more active and form complexes with phosphorus. Again P use efficiency is reduced. Nitrogen use is not affected much by acidity. Addition of lime (CaCo3) to acidic soils brings soil pH to neutral. Thus P use efficiency is improved.

Diammonium phosphate is a very popular fertilizer because of its excellent physical properties and nutrient content.
Diammonium phosphate is free flowing, dust-free and does not normally give any storage problem.
Diammonium phosphate is almost water-soluble and ultimately leaves acid effect on soils because of ammonia (NH4) it contains.
Diammonium phosphate on incorporation into soil, reacts with water and gets converted into HPO4 and NH4. Ammonium (NH4) follows the same routes as in case of urea. Phosphorus in DAP is present in best available from (HPO4). Depending upon the soil reaction (pH), phosphorus exists in 3 forms which can be absorbed by plant roots. These are HPO4, H2PO4 and PO4. Phosphorus, which is immobile in soil, is not subjected to leaching losses.

Uses
One of the major cropping fertilisers used in Australia as a source of both phosphorus and nitrogen. The high phosphorus content makes it a true high analysis fertiliser.
Diammonium phosphate and blends of DAP are used on a range of crops in broad-acre farming, cereals, sugar cane, sowing pastures, dairy pastures, fodder crops and also in horticultural crops; for example, vegetables and tree crops.

Used as complex fertilizer for supply of 'N' and 'P2O5' nutrients.
Mainly used in basal application of fertilizers due to slow releasing nature of Diammonium phosphate.

Diammonium phosphate is the most popular phosphatic fertiliser because of its high analysis and good physical properties. The composition of Diammonium phosphate is N-18% and P2O5 -46%.

Diammonium phosphate is very suitable when it is not necessary to supply potassium to the soil and for crops that are demanding in phosphorus.

Ammoniacal nitrogen facilitates the absorption of phosphorus.
The phosphorus is totally assimilable by the plants and 95% soluble in water, guaranteeing an excellent agronomic result.
Diammonium phosphate has a residual acidic effect on soils, although initially Diammonium phosphate has an alkaline reaction, making it very suitable for neutral or basic soils.

-Diammonium phosphate is specially applicable to the soil in the north;
-Diammonium phosphate is applicable for all kinds of plants in large fields;

INFORMATION
Because of its nutrient composition, DAP is also referred to as 18-46-0 in the trade.
Diammonium Phosphate (DAP) is a highly water-soluble nitrogen phosphate used in a number of multi- component fertiliser mixtures as well as in directly applied compound fertilisers. Aside from Monoammonium Phosphate (MAP), it is the world’s most commonly used phosphate fertiliser, with annual production reaching almost 50 million mt. Phosphates are mined in the form of rock phosphate. Phosphates react with sulphuric acid to produce phosphoric acid, which in turn reacts with ammonia. This process converts the poorly water-soluble rock phosphate into a water-soluble phosphate fertiliser that is easily assimilated by plants.
Diammonium Phosphate is a grey or beige-grey granular substance. DAP is sometimes impregnated with a dust-suppressant oil, giving it a dark brown colouring.

FEATURES
