Diammonium Phosphate

Description

Diammonium phosphate (DAP or diammophos) is a complex, highly concentrated, granular mineral fertilizer with excellent physical properties. It contains two main nutrients in its composition — 18% nitrogen (N) and 46% phosphoric pentoxide (P₂O₅) or in total 63% of the active substance. It is obtained through a reaction between phosphoric acid (P₂O₅) and ammonia (NH₃). It is incompatible with other alkaline chemicals due to the fact that its ammonium ions turn into ammonia when they get into the medium with higher рH. This product of high quality is easily input into the soils, it is highly soluble, it is not hygroscopic and has a granular form with equal in size granules, which are evenly dissipated along the soil surface.

Diammonium phosphate is used for the pre-sowing fertilization of winter and spring crops under irrigation conditions. It is suitable for fertilization of soils rich in potassium. Because of the fact that it is water-soluble, it has the properties of fast-acting phosphorus fertilizer, and the low mobility of the phosphorus in the soil allows its use for main, stocking as well as periodic fertilization. No additional pre-sowing fertilization with nitrogen is needed in autumn crops.

It may be applied directly into the soil with the help of conventional equipment for spraying.

It is stored in well-ventilated, cool and dry storehouse premises which do not allow for moistening or direct sun heating.

Heating, leaving it in the open air, mixing it with water or with strong bases and with sodium hypochlorite should be avoided.

Product FAQs

When to Use

Autumn, Spring

Nitrogen’s Role in Plants

Nitrogen is always the nutrient in highest demand by plants, due to the greater content of nitrogen present on a dry weight basis in comparison to any other nutrient.
Nitrogen is a primary component of amino acids which are the building blocks of proteins. Thus, by adding nitrogen to soil the protein content in plants is increased.
Nitrogen is part of the chlorophyll molecule and a part of numerous enzymes and coenzymes. Chlorophyll is responsible for photosynthesis, where sunlight is absorbed and stored in the plant as sugars and proteins.
Therefore, nitrogen is an integral part of photosynthesis.
Signs of nitrogen deficiency – reduced plant growth, yellowing of the leaf, early crop maturing.

Phosphorus’s Role in Plants

The most important role of phosphorus is the storage and transfer of energy that is generated through photosynthesis along with the metabolism of carbohydrates.
Phosphorus is an essential compound of Adenosine Triphosphate (ADP), the energizing component driving plant development.
Phosphorus deficiency has a huge impact on plant growth and reproduction, reducing the plant processes noted below.
Processes aided by phosphorus:
- Large root growth
- Early formation of plant shoots
- Improved stalk and stem strength in crops
- Improved fruit, vegetable, and grain quality
- Seed formation
- Resistance to moisture and colder temperatures

Why Use DAP?

DAP is a versatile and cost-effective form of nitrogen and phosphate. When there are requirements for both nitrogen and fast-acting phosphate DAP should always be considered. DAP blends well with most other fertilizers making it a good base to build a complex fertilizer blend from.

The benefits of using DAP:

DAP is suitable for use when crops and pastures require equal amounts of phosphate and nitrogen
DAP is the cheapest form of phosphate when nitrogen is also required and full value is obtained out of the nitrogen portion
DAP is a high-analysis product reducing freight and application costs when compared to alternatives
DAP contains nitrogen in ammonium form which is less susceptible to volatilization losses compared to urea nitrogen, resulting in increased nitrogen utilization
