Product Description

Diammonium phosphate is abbreviated as DAP and it is a series of the water soluble ammonium phosphate kind of salts which can be produced once phosphoric acid and ammonia react. The solid ammonium phosphate shows a kind of dissociation pressure.

The uses

DAP is a fertilizer and when applied as food for plants, the soil pH is increased temporarily. When used on a long term basis, the ground becomes more acidic than before the ammonium nitrification. The fertilizer is not compatible with other alkaline chemicals due to the fact that the ammonium uon is likely to convert the ammonia in a pH environment that is quite high. The average solution pH stands at 7.5 to 8. Typical formulation stands at 18-46-0. This translates to 18% N, 46% P205 and 0% K20.

Diammonium phosphate fertilizer is widely used all over the world because of its phosphorus content. This is a fertilizer that is made from tow constituents that are common within the fertilizer industry and it is more popular due to the relatively high content of nutrients and the physical properties that are totally excellent.

Its production

His class of fertilizers became available during the 1960s and DAP rose in its popularity within the class. Its formulation is made in a way that it has a reaction that is controlled between ammonia and phosphoric acid. A slurry is produced and this is what is cooled so as to granulated and then sieved.

The storage and handling properties of the fertilizer are excellent. The grade of DAP that is standard stands at 18-46-0. Other fertilizer products that have a nutrient contents that is much lower cannot be labeled as DAP.

There are inputs that are required for the production of the fertilizer and for one to; 1.5-2 tons of phosphate rock, 0.4 tones sulfur so as to dissolve this rock and then 0.2 tons ammonia are needed so as to create the fertilizer. Any changes in price or supply of such inputs impacts the availability as well as the prices of the DAP.

DAP has a very high content of nutrients which helps in many ways. It reduces the handling, application as well as the freight costs. This is a fertilizer that is widely produced in all parts of the world and it is greatly traded in different localities.

Agricultural use

Di ammonium phosphate fertilizer is one massive source of P and N which is very much needed in the nutrition of plants. Its solubility is quite high and this means that it dissolves in a very quick way when in the soil so as to make sure that the pants receive the much needed ammonium and phosphate. One of the most notable property of DAP is the pH which develops all around a granule upon dissolution.

Usually, ammonia gets released when the DAP granules dissolve and this ammonia can be quite volatile and this makes it to be quite harmful to different seedlings as well as the roots of plants which are at close proximity with it. The potential damage becomes even more common when the pH of the soils is much higher than 7. This is a condition which is quite comon around the granules as they dissolve. So as to make sure that the seedling damage is minimized, you need to take a lot of care so as to avoid the placement of the DAP in its high concentration just near the germinating seeds.

Diammonium phosphate also has ammonium within and this is one amazing N source. This is something that the soil is able to convert into nitrate over time. This leads to a pH drop eventually. This means that the increase in the soil pH around granules is usually temporary. The initial rise in the pH around the granules can usually influence the reactions that are micro sites of soil organic matter as well as phosphate.

Management practices

In the chemical reaction that is initial, there are certain differences between some of the commercial fertilizers in soil but the dissimilarities usually become very minor with time and are very minimal where plant nutrition is concerned.

Many of the filed comparisons done between DAP and monoammonium phosphate shows very minor differences on the growth and the yield of the plants due to the P when proper management is present.

This fertilizer has gained a lot of popularity especially between different growers in the present day. It can be used on a wide variety of plants.

Each and every granule of this fertilizer has a high analysis phosphorus and nitrogen. The granule size usually stands at 3-4mm. it is a product that is free flowing and gas a bulk density of some 0.9 tonnes/cubic meter. This is a fertilizer that can be blended with yet other products as well as different element for an even more fascinating outcome.

The features

It is a very high analysis phosphorus source and the ratio is 1:1 and this is something that makes it such a good source of nitrogen. When you used DAP free ammonium is released. The nitrogen which is in the form of ammonia helps resist leaching and it also has a much slower nitrogen release.

The ammonium which is free gives a reaction which changes the pH to be higher immediately all around the granule.

The fact that the nitrogen contained in diammonium phosphate fertilizer is low allows it to be a very cost effective nitrogen source especially in cases where the phosphorus is also much needed.

The mixture during production is done in the ratio of 1:1. The ammonia is then granulated, then dried and lastly screened.

More on the uses

This is a fertilizer that is used widely for purposes of cropping in different areas in the world and it proves to be an amazing source of nitrogen as well as phosphorus. The fact that the phosphorus content is much high allows it to stand as one of the greatest true analysis kind of fertilizer.

DAP and the different blends can be used on a wide range of crops in broad acre farming, the horticultural crops such as tree crops and vegetables, fodder crops, dairy pastures, sowing pastures, sugar cane, and cereals among many others.

Handling and storage

Diammonium phosphate fertilizer ends o take in some moisture while in the field and also when in storage.

It is highly recommended that the fertilizer be stored in bulk and within a shed. When you cover using a tarp, you can very well reduce the moist air uptake which is not good for the fertilizer.

Note that using augers can actually damage DAP and make it even harder to handle. Make sure that the fertilizer is not lefty exposed to the moist air.

You should empty or fill completely the air seeder or drill fertilizer box when you need to keep it overnight. Make sure that this seeding equipment remains well covered using a tarp.

The tynes of the equipment should be raised from soul so as to make sure that no moisture is a le to move up tubes.

The restrictions

When it comes to the sowing period, there is a very small risk involved that germination will be affected even at the rates that are high. As a general rule, you should only use a maximum of 20kg for every ha of the nitrogen at cereal seeding

For sowing there is little risk of affecting germination, even at high rates. The general rule of a maximum of 20kg/ha of nitrogen at seeding of cereals should be used.

When applying the DAP, make site that it is banded some 5 cm from seeds either at the side or below.

Diammonium phosphate fertilizer has a low sulphur content which is at 1.5%. It is not a recommendation for the crops that require sulphur so as to flourish like canola unless such fertilizers are needed with the sulphate of ammonia.

This fertilizer should never be stored within a silo.

The description

Diammonium phosphate fertilizer has got nutrients with different composition within and they include 46% of P205 as well as ammonical nitrogen which is at 18%. DAP is able to give the right phosphate proportion as well as the nitrogen which is needed for farming vegetables, barley and wheat. In the early stages of the orchard fruit fertilization, it can be applied.

Handling this product is not highly hazardous and it can actually be considered to be relatively safe.

This fertilizer is used in broadcasting, for banding where the soils are calcareous, for vegetables, fruits as well as grains.

This product is usually stored within bags and in bulk. This hydrogen phosphate fertilizer has proven to be an amazing compound fertilizer.

For maize that is supposed to be used for grains, the dosage should be 20-30. There are different factors that need to be considered when you want to come up with the dosage of diammonium phosphate fertilizer. You should consider current analysis of the soil, the quality class as well as the agronomical category.
