Arizona mine tailings sold as Minnesota fertilizerBy Mary Losure

For home gardeners, spring planting is just a few weeks away. But if you're planning to add fertilizer to the soil, reading the product's label won't always tell you whether it's safe.
In most states, including Minnesota, manufacturers can sell fertilizer containing arsenic, lead, cadmium, and other heavy metals without disclosing those ingredients. In Minnesota, that means a product called Ironite is still on the market, despite high levels of contamination.
When Carl Rosen, now acting head of the Horticulture Department at the University of Minnesota, wanted to improve the soil around his blueberry bushes, he went to a local garden store and bought a 25-pound box of Ironite.
The label listed the product's beneficial plant nutrients, such as nitrogen, iron, and sulfur.
But it neglected to mention another ingredient - arsenic.
"I actually used some of this, not knowing that it had arsenic in it, and I put it in a small area where I was growing some cranberries and lingonberries, that are acid loving plants," Rosen says. "One of the cranberries died where I put it, and I actually went in and measured the amount of arsenic in the soil. And the native level of arsenic's about one part per million in soils around here, and it was 100 parts per million."

In the last 30 years, the dead zone has become an annual summer phenomenon, fed by rising use of nitrate-based fertilizers by farmers in the Mississippi watershed, Rabalais told Reuters.
The nitrates, carried into the gulf’s warm summer waters by the river, feed algae blooms that use up oxygen and make the water uninhabitable.
The dead zone’s size has varied each year depending on weather conditions, but averages about 5,000 square miles (13,000 square kilometers) and remains in place until late September or early October.
Virtually nothing is being done to stop the flow of nitrates into the river, meaning the dead zone will reappear every year, Rabalais said.
