Marvin Van Haaften, director of the Governor's Office of Drug Control Policy, said the chemical, known as calcium nitrate, can be added to each of the 26,000 tanks used for application of anhydrous ammonia in Iowa. Calcium nitrate renders the anhydrous ammonia useless as a seedstock for methamphetamine, Van Haaften said. "This is a big deal," Van Haaften said. Ninety percent of meth used in Iowa is imported from Mexico, so the chemical additive won.t have an impact on that, he said, but it will be a serious barrier for Iowa-based meth makers. - --- MAP posted-by: Richard Lake
