Despite being banned in countries such as Afghanistan, China, Colombia, Germany, Ireland and the Philippines, the potentially explosive fertilizer ammonium nitrate can be purchased pure and by the ton in the United States, according to the Dallas Morning News.
An investigation by the newspaper found that "for more than a decade, U.S. efforts to tighten controls over ammonium nitrate fertilizer have repeatedly failed, bogged down by bureaucratic gridlock and industry resistance. Regulations approved years ago remain unenforced and unfinished. Mere talk of safer substitutes has been blocked by those with profits at stake."
Looks like you haven't made a choice yet.
