Diammonium phosphate (DAP) is the world’s most widely used phosphorus (P) fertilizer.
Diammonium phosphate 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.
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.
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 is used as complex fertilizer for supply of ‘N’ and ‘P2O5’ nutrients.
Diammonium phosphate is mainly used in basal application of fertilizers due to slow releasing nature of DAP.
Uses of Diammonium phosphate:
DAP 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 of Diammonium phosphate in solution is 7.5–8.
The typical formulation of Diammonium phosphate is 18-46-0 (18% N, 46% P2O5, 0% K2O).
DAP 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.

DAP is also used as a yeast nutrient in winemaking and brewing mead; as an additive in some brands of 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, powder for use in winemaking.
Diammonium phosphate is the basic nitrogen source in nearly all wine yeast nutrients.
Diammonium phosphate can be used by itself or to augment some of the more expensive complete nutrients.
At certain stages of fermentation Diammonium phosphate will help inhibit formation of reduced sulfur compounds.
Diammonium phosphate is best if used early rather than later in the fermentation.

Properties of Diammonium phosphate:
Diammonium phosphate is a two-nutrient fertilizer.
Diammonium phosphate contains 18% nitrogen (N) and 46% phosphorus (P) as P2O5.
Since Diammonium phosphates nitrogen content is in ammonium (NH4) form, it is particularly effective in the first development stages of plants.
When used as a base fertilizer, Diammonium phosphates nitrogen content may not be sufficient to provide plants’ need.
Therefore, if diammonium phosphate is preferred as starter fertilizer, plants must be supported with other nitrogencontaining fertilizers in top dressed fertilization.
Since Diammonium phosphates nitrogen content is in ammonium (NH4) form, it is easily retained by soil.
So no nitrogen loss occurs because of washing as a result of excessive precipitation or excessive irrigation.
Agricultural Use of Diammonium phosphate:
As rest of the world, diammonium phosphate fertilizer is used as a phosphorous fertilizer in our country, too.
As a plant nutrient, phosphorus is essential for root development during early growth stages and very important for energy metabolism.
In case of not applying at sufficient depth or in sufficient rate, phosphorus deficiency arises in plants so dramatic decreases occur in yield and quality.
In our webpage, you may achieve detailed information under title of “Fertilization Recommendations”.
Applications of Diammonium phosphate:
The effectiveness of diammonium phosphate fertilizer particularly in the calcareous soils with pH above 7.5 is higher than triple superphosphate (TSP).
As Diammonium phosphate is the case with other phosphorous fertilizers, a portion of phosphorus existing in diammonium phosphate fertilizer combines with calcium (Ca) that is abundant in calcareous soils and becomes non-available for plants.
However, Diammonium phosphate can transform again to useful form as a result of certain physicochemical processes in soils.
Therefore, all phosphorous fertilizers including diammonium phosphate must be banded with special equipment instead of spreading. .
As the case for other compound fertilizers, diammonium phosphate is applied in advance of or during seeding and incorporated with soil considering the effective root deepness.
Applying Diammonium phosphate after seed germination will not have any effect on phosphorus nutrition of plants.
The reason of this is that phosphorus retention by soil particles and as a result of this, hindered horizontal movement.
Phosphorus can reach up to a depth of only 5-6 cm with precipitation.
Therefore, in diammonium phosphate application 5-6 cm below the seeding depth must be aimed.
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.
Natural occurrence of Diammonium phosphate:
The compound occurs in the nature as the exceedingly rare mineral phosphammite.
The related dihydrogen compound occurs as the mineral biphosphammite.
Both are related to guano deposits.
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.”

Diammonium phosphate (DAP) is produced from industrial phosphoric acid that contains large amounts of anionic and cationic impurities (Co, Cu, Fe, Mn, Mo, Ni, Zn, F, As, Al, Hg, Pb and Cd).
Consequently all those impurities will be found in DAP.
However, the industrial DAP obtained can be used as fertilizers, but cannot be used for some industrial application like pharmaceutics and cosmetics.
After purification, the price of DAP is three times more expensive than the same product before purification.
The procedure for purification of industrial DAP is a recrystallization, by using several mixtures of solvents.
The physicochemical characterization of this fertilizer upstream and downstream from the purification, through spectroscopic analyses and chemical analyses, shows that recrystallization eliminates impurities.
Purified DAP was obtained, the physicochemical properties of which are comparable to those of the pure commercial DAP (Fisher).

INFORMATION about Diammonium phosphate:
Because of Diammonium phosphates 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), Diammonium phosphate 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.
DAP is a grey or beige-grey granular substance.
DAP is sometimes impregnated with a dust-suppressant oil, giving Diammonium phosphate a dark brown colouring.
FEATURES of Diammonium phosphate:
• High analysis source of phosphorus.
• DAP releases free ammonium. Nitrogen in the ammonium form resists leaching and is a slower release form of nitrogen.
• The free ammonium gives a higher pH reaction immediately around the granule.
• The low cost of nitrogen in DAP makes it a cost effective source of nitrogen if phosphorus is also required
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 Diammonium phosphates content is in the form of ammonium (NH4 +), so Diammonium phosphate 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.
DAP 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, Diammonium phosphates application after germination does not show Diammonium phosphates effect.
Production of Diammonium phosphate:
Ammonium phosphate fertilizers first became available in the 1960s, and DAP rapidly became the most popular in this class of products.
Diammonium phosphate’s formulated in a controlled reaction of phosphoric acid with ammonia, where the hot slurry is then cooled, granulated and sieved. DAP handles and stores well.
The standard nutrient grade of DAP is relatively high, at 18-46-0, so fertilizer products with lower nutrient content may not be labeled DAP.
The inputs required to produce one ton of DAP 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 DAP prices and availability.
The high nutrient content of DAP helps reduce handling, freight and application costs.
DAP is produced in many locations in the world and is a widely traded fertilizer commodity.
DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition.
Diammonium phosphate’s highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium.
A notable property of DAP is the alkaline pH that develops around the dissolving granule.
As dissolving DAP granules release ammonium, the seedlings and plant roots nearest the volatile ammonia can be harmed.
This potential damage more commonly occurs when the soil pH is greater than 7, a condition that often exists around the dissolving DAP granule.
To prevent such damage, users should avoid placing high concentrations of DAP near germinating seeds.
The ammonium present in DAP 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 DAP granules is a temporary effect.
This initial rise in soil pH neighboring DAP can influence the micro-site reactions of phosphate and soil organic matter.
What is Diammonium phosphate?
Ammonium phosphate dibasic ((NH4)2HPO4), also known as diammonium phosphate and diammonium hydrogen phosphate, is a water-soluble ammonium phosphate salt that is produced when ammonia reacts with phosphoric acid.
Ammonium phosphate dibasic has various industrial uses, including as a yeast nutrient in winemaking and to aid in cheese culturing, as a phosphate source in fertilizers, and as a component of commercial fire-fighting materials.
In pharmacy, Diammonium phosphate has been as an antirheumatic.
Diammonium phosphate Management practices
Differences in the initial chemical reaction between various commercial P fertilizers in soil become minor over time (within weeks or months) and are minimal as far as plant nutrition is concerned.
Most field comparisons between DAP and monoammonium phosphate (MAP) show only minor or no differences in plant growth and yield due to P source with proper management.
Non-agricultural uses
DAP also acts as a fire retardant.
For example, a mixture of DAP 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.
DAP is used in various industrial processes, too, such as metal finishing.
And, Diammonium phosphate’s commonly added to wine to sustain yeast fermentation and to milk to produce cheese cultures.
What is DAP?
DAP is a water-soluble inorganic phosphate salt, mostly used in the baking industry as a synergistic ingredient in breadmaking.
Incorporation of of the salt is helpful for:
-Providing phosphorus and nitrogen, vital nutrients for yeast cells
-Enhancing growth of yeast cells
-Helping yeasts to absorb other micronutrients
-Speeding up fermentation reactions (enhancing metabolic production, e.g., carbon dioxide and alcohol)
-Controlling pH of sponge doughs, due to its buffer nature
-Strengthening and conditioning dough mixtures
Commonly known as DAP, Diammonium Phosphate is manufactured by reacting 1 mole of phosphoric acid (produced from mined phosphate rock) with 2 moles of ammonia; the resulting slurry is solidified into a granular form.
Di-ammonium hydrogen phosphate (DAP) is a water-soluble ammonium phosphate.

Diammonium Phosphate
Diammonium phosphate is an inorganic compound, and a salt of phosphoric acid.
Phosphate and organic phosphate are esters of phosphoric acid.
Phosphate is a natural resource that is found under the surface of the earth, where Diammonium phosphate is exploited to use the phosphor in multiple agricultural and industrial activities.
DAP (diammonium phosphate) is a major source of nitrogen for low-malt or sugar-rich mashes and washes.
Recommended to add the dose in stages during the first half of fermentation.
DAP stimulates fermentation rate, so if too much is added at once, the yeast may ferment too fast and too hot.
Production Method:
Ammonia is imported from Arab and foreign countries by ships, where Diammonium phosphate is pumped through a pipe with a diameter of 14 inches to a tank with a storage capacity of 30,000 tons, and a second tank with a storage capacity of 10,000.
Ammonia temperature in the tanks is continuously kept at (-33 oC) using special compressors.
Ammonia is pumped to the reactor, where Diammonium phosphate reacts with concentrated phosphoric acid to produce slurry, which is pumped to a fertilizer granulator to be mixed with the fertilizer returns.
Additional ammonia is added to the granulator to reach the required mixtures.
Using the hot gases produced by the burning fuel oil, Fertilizer is then dried, so Diammonium phosphates moisture content doesn’t exceed 1.5%.
Fertilizer is conveyed to sieves to get the required size, cooled down in a machine similar to the dryer, and then sent to the storage silos.
Diammonium phosphate Usages:
The fertilizer is used either directly or as an input to produce other fertilizers such as liquid and suspended compound fertilizers.
Application of DAP
