How to make Iowa greener: New Ecological Technologies surface in and near the Hawkeye State
By JIM MALEWITZ
Dirty air, polluted waters, tainted land and flooded land. Iowa faces a myriad of environmental problems.
Thanks largely to the state’s central role in the nation’s agriculture, Iowa is widely known as the most human-altered state in the country. And it faces consequences.
Brian Hornbuckle, an Iowa State University professor, is trying to improve crop yields and predict flooding by measuring soil moisture – from space.
Some say that a proposed 400,000 barrel-a-day tar sands oil refinery near the Iowa-South Dakota border will employ the greenest technology. But researchers don’t know they details. The controversial plant may never be built after all as its builder slogs through the permitting process.
