Corn fertilizer could feed the dead zone, something that appeared off the coast this summer. It was a 17-hundred square-mile area of oxygen-depleted water.
Dr. Dimarco investigated, "If oxygen is depleted then fish, shrimp, clams, anything that needs oxygen to breathe, will be affected."
This summer, all that rain we had created a stifling layer of fresh water on top of the salt. Next year, nitrogen from corn crops could increase the size of the dead zone or make it stick around longer.
"If the dead zone lasts the whole year because of more severe conditions that could be a real problem to the shrimping industry off of
A boon to farmers may not help marine life. It weighed heavily on one customer.
Jessica Loretto says, "It makes me think. I really don’t want to buy [corn] anymore."
She put all of her corn back. She didn’t want to support one resource at the expense of another.
Right now, storms that come through break up the dead zone and give marine life time to recover. Experts will be carefully watching the effects of corn fertilizer on the
