Study: Less fertilizer in Illinois River, good news for Gulf
CHAMPAIGN, Ill. (AP) — The flow of nitrates from farm fertilizer and treated wastewater into the Illinois River that contributes to a dead zone in the Gulf of Mexico has fallen, a new study says. Researchers believe one likely factor, the use of newer, more robust varieties of corn, could make the drop a long-lasting one.
The study from the University of Illinois found that the level of nitrates dropped 10 percent between 2010 and 2014. Adding in data from 2015 that was not available when the study was being written, that level dropped by 15 percent, one co-author said.
