A High-Tech Approach to Studying Iowa's Future Soil Health

Farmers in Iowa are studying interactions between crops, water usage, carbon and nitrogen storage, and how those factors combine to affect longterm soil biodiversity. It's part of a seven-state project in the Midwest.

Researchers are looking at the effects of crop combinations on soil and moisture across the Corn Belt.

Iowa State University Agronomy Professor Sotirious Archontoulis is running one research site in the five-year, $16 million project.

He's monitoring how crop management, carbon and nitrogen content affect soil moisture - and will try to predict the impact on the viability of future crops.

"We have the same setup in many different environments to capture different organic matter, soil hydrology conditions," said Archontoulis, "so we get a better understanding of the complexities in the agronomic system."

Archontoulis said scientists can also study greenhouse gas emissions from the soil.

He said these ultimately affect its health and can have an impact on large ag operation waste runoff, which is known to pollute nearby ground and surface water. The research is gearing up now.
