WASHINGTON — Honeywell said Tuesday it has developed a nitrogen-based fertilizer that is difficult to ignite — a discovery that could reduce criminals’ ability to make explosives used in major terrorist attacks like the Oklahoma City bombing. Honeywell said its patented fertilizer combines ammonium sulfate with ammonium nitrate, providing the nitrogen and sulfur needed for plant nutrition but making it largely useless as a fuel for explosives. When mixed with substances such as fuel oil the new fertilizer did not detonate, it said.
“Ammonium nitrate has long been an excellent fertilizer, but this technology makes it safer,” said Qamar Bhatia, vice president and general manager of Honeywell Resins & Chemicals. The Associated Press
