Let us hope that the ban will be enforced properly.

At the outset let us not forget, we are agriculture based country and we require the white crystals- Ammonium Nitrate in bulk. 
Although the explosion is not that big as done using gelatine or other materials but devastation and destruction is seen after each blast and they only know what was it who
is he sufferer. They only know what is pain and aftermath effect.
I recommend instead ban on it Govt and agencies/sellers must maintain a detail of material purchased may be in bulk or whatever be the quantity with proper name, address, proof etc of persons carrying the white crystal. This way we can monitor better.

Thanks for sharing Mr. Rajeev Ji,
My perception is that there must be a strong checking for the buyers rather than banning it and let our crops and agriculture industry come to a stand still when we claim to be the agriculture priority nation. Are you aware that even the detergent we use to clean clothes and utensils can be a very deadly bomb? So what next........... banning those too? Rajeev Ji this is not the solution but a spark to ignite another agitation by the farmers because of being the mostly used fertilizer status of ammonia  nitrate and phosphorous potassium salts or simply put the Urea and NPK fertilizer.
I am a farmer by birth so I know how important is the stuff and putting a ban would be more of cowardliness and laziness of the present government or system.   

Good move in deed! thanks for informing us Mr. Sharma.

The Indian government needs to think things through very carefully. Ammonia nitrate is used as a fertilizer by farmers. A complete ban would lower Indian crop yields thus producing less food and causing food prices to rise further.

Thanks Mr. Rajeev for referral.  The Government should have classified Ammonium Nitrate as an "Explosive", under Section 17 of the Explosive Act of 1884, long time back.  This fact was very well known. The increased use of Ammonium Nitrate, a common fertilizer, as an explosive has substantially complicated India's fight against terrorism!  Though delayed action, Mr. Rajeev, this action will bolt the future bomb-making process using this chemical, which was hitherto, freely available in local market!

It is a good move to ban Ammonium Nitrate. But Govt must also ensure (with proper checks) that it is not smuggled or sold in black market.
