Know about High Density & Low Density Ammonium Nitrate

High Density Ammonium Nitrate (HDAN) is a nitrogenous dry fertilizer product. It is differentiated from Low Density Ammonium Nitrate (LDAN), which is a grade used essentially in explosive applications and is sometimes referred to as Industrial Grade Ammonium Nitrate. Ammonium nitrate is recognized as the most effective, and efficient form of nitrogen fertilizer.  

We know that Nitrogen is one of the key needs for successful plant growth. This macro-nutrient is responsible for the green, leafy production of a plant and enhances overall health. Nitrogen is attained from the atmosphere, but this form of nitrogen is difficult for plants to uptake due to its strong chemical bond. Nitrogen that occurs in treated fertilizers includes ammonium nitrate.

Starting with a simple reaction of anhydrous ammonia and nitric acid, ammonium nitrate is produced. To get ammonium nitrate in solid form, the resulting liquid is concentrated and processed into prills, granules or crystals. The concentrated solutions can also be used to bring out urea-ammonium nitrate solution (UAN) which is used in liquid fertilizer systems. Both these forms are important agricultural products which can be directly applied to the soil or used as components in bulk blended NPK fertilizers.

Ammonium Nitrate does have some drawbacks also: It is a strong oxidizer and can explode under certain conditions. So there are restrictive regulations for its handling and use in some countries. Another challenge for ammonium nitrate in both the forms is that it has a critical relative humidity much lower than other fertilizers.

Deepak Fertilisers and Petrochemicals Corporation Ltd. (DFPCL) is one of the leading technical ammonium nitrate manufacturers in the world. In India, they are the only producer of explosive grade Low Density Ammonium Nitrate (LDAN). They manufacture various types of Technical Ammonium Nitrate products with different technologies according to customer’s requirements.
