The Description Of Diammonium Phosphate DAP 18-46-0:

Diammonium Phosphate DAP 18-46-0 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.

 

Diammonium Phosphate DAP 18-46-0 Agriculrural Use

Diammonium Phosphate DAP 18-46-0 fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It is highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of Diammonium Phosphate DAP 18-46-0 is the alkaline pH that develops around the dissolving granule.

As ammonium is released from dissolving Diammonium Phosphate DAP 18-46-0 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 DAP 18-46-0 granule. To prevent the possibility of seedling damage, care should be taken to avoid placing high concentrations of Diammonium Phosphate DAP 18-46-0 near germinating seeds.

 

The ammonium present in Diammonium Phosphate DAP 18-46-0 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 18-46-0 can influence the micro-site reactions of phosphate and soil organic matter.

 

Management Practices

There are differences in the initial chemical reaction between various commercial P fertilizers in soil, but these dissimilarities become minor over time (within weeks or months) and are minimal as far as plant nutrition is concerned. Most field comparisons between Diammonium Phosphate DAP 18-46-0 and monoammonium phosphate (MAP) show only minor or no differences in plant growth and yield due to P source with proper management.

Diammonium Phosphate (DAP 18-46-0) 

Non Agricultural Uses

Diammonium Phosphate DAP 18-46-0 is used in many applications as a fire retardant. For example, a mixture of DAP 18-46-0 and other ingredients can be spread in advance of the fire to prevent a forest from burning. It then becomes a nutrient source after the danger of fire has passed. DAP 18-46-0 is used in various industrial processes, such as metal finishing. It is commonly added to wine to sustain yeast fermentation and to cheese to support cheese cultures.

Application:

 

-Diammonium phosphate is one kind of high concentration quick slow fertilizer , which is used in all soil and plants. It can be used both as base and top dressing fertilizer. Please note it should be buried deeply when fertilize.

-Based on nutrient, we have DAP64% and DAP 60%

-Based on color, we have natural color , dark brown color, green color and yellow color.

-Industrial grade As a fire-prevention agent for fabric, timber and paper.

-For food grade it is mainly used as a fermentation agent, nourishment,

-Used as a high effective non-chloride N, P compound fertilizer in agriculture.

-It is a quick acting manure in high concentration. It could meet the Nitrogen and phosphrus requirement of various crops and plants, using as base fertilizer, seed fertilizer and top application, especially in the drought, rainless area with deep placement. It could be widely used in vegetables, fruits, paddy rice and wheat, especially in P deficient soil.

 

 

Application in Fertilizer

Diammonium phosphate(DAP) is a widely used as a source of P and N fertilizer which Excellent for low pH or alkaline soils

 

Mainly used as Timber, paper, fabric extinguisher , fire retardant coating additive, and dispersant for fibre processing and dyeing. DAP is a high effective compound fertilizer in agriculture. It provides the correct proportion of phosphate and nitrogen needed for farming wheat, barley and vegetables. It is applied in the early stage of fruit orchard fertilization.

 

 

Storage & Handing

1.Do not ingest. Do not breathe dust. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes.

2.Store in cool, dry, ventilated area.

3.Isolate from incompatible substances, particularly alkaline material, as ammonia gas will be released.

 

Non Agricultural Uses

1.Used as a fire retardant.

2.Used as a yeast nutrient in winemaking and brewing mead.

3.Used as an additive in some brands of cigarettes purportedly as a nicotine enhancer.

4.Used as a Flux for soldering tin, copper, zinc and brass.

5.Control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.

 

Usage of Diammonium Phosphate                                                               1.excellent source of phosphate and nitrogen for plant

2. mainly used as the raw material of BLENDING NPK.

3.It is fire-extinguishing agent for fabrics, woods and paper.

4.It is used as a high effective non-chloride N & P compounds fertilizer in agriculture.

5.It contains totally 74% fertilizer elements and can be used as a basic raw materials for N, P, K, compound fertilizer.
