Naturally, the Australian Government is trying to ban ALL sales of ammonium nitrate.quote:
Companies aim for bomb-proof fertilizer
BELTON, Mo., March 17 (UPI) -- U.S. companies are working to neutralize ammonium nitrate's explosive capabilities while also making the easily acquired fertilizer traceable.
The fertilizer can be highly explosive when mixed with fuel oil and was used in the 1995 Oklahoma City bombing, the 1993 World Trade Center bombing in New York, and others.
New Scientist magazine said most countries do not regulate its sale, but the European Union keeps tight restrictions on the fertilizer, where granules must be too large to absorb fuel oil.
Specialty Fertilizer Products, based in Belton, Mo., is patenting a water-soluble polymer coating for the fertilizer granules that repels fuel oils. The coating dissolves in soil, so it should not interfere with the nitrate's function as a fertilizer, New Scientist said.
