The storage of fertilizer for a long period brings about detrimental changes in its characters and measures to overcome this have to be taken to avoid loss in fertilizer quantity.
Most commercial fertilizers especially if there is a high concentration of nutrients, are hygroscopic and have a high solubility in water. When stored in bulk for long periods, they are subjected to high humidity and varying atmospheric conditions leading to caking, loss in its properties and strength.

The fertilizer, when taken out of silos for bagging, is very hot and thus, extremely hygroscopic. It is essential to control humidity levels in the area during this period for free flow of fertilizer, through auto-bagging machines into the polythene bag without lumping and caking.

Almost all types of fertilizers are essentially stored at ambient temperature conditions but relative humidity needs to be controlled at 40%. If the humidity goes above 40%, the prills, being very hygroscopic, absorb moisture causing them to stick to each other rendering the product useless. Another side effect of high humidity is that in contact with hydrocarbon, the ammonium nitrate becomes explosive in nature. Hence, it becomes very important that humidity be kept or held below 40%

The Solution
To overcome the problems arising out of hygroscopic nature of fertilizers, it is necessary to condition the air inside the warehouse and storage sites, so that the fertilizer does not absorb moisture from the atmosphere.
Bry-Air Dehumidifiers maintain these conditions with ease regardless of ambient temperature

Dehumidification is essential/ critical in the following areas

• The prilling tower - low humidity improves the prills
• Bulk Storage - to protect the prills etc.
• Bagging operations - for the ease in handling of prills etc.
