More than half the crop produced in Indiana is exported, with China being one of soybean's main importers.

As of this week, 70 percent of the state's corn has been harvested - compared to 85 percent at this time last year.

The soybean crop is on track as of this week, but corn is less than half harvested - putting family farms like White Oak Farms in Putnam County under the gun.

The state's soybean crop is 42 percent harvested as of this week, about the same as average. But the corn crop lags at just 24 percent.

Research says the controversial herbicide damaged several million acres of soybeans and specialty crops in the Midwest since it came into use last year.

That means continued tight profit margins for farmers and more low food prices for consumers.

The USDA expects farmers in Indiana and nationwide to plant more soybeans than ever this year, while corn acreage looks to hold steady.

Indiana farmers are harvesting a record amount of soybeans, but those gains are being offset by lower than expected corn yields.

Indiana farm revenues are expected to increase by about $500 million over last year. However, with land, equipment and labor costs, profits will still be low.

Researchers at the new Indiana Corn and Soybean Innovation Center will study the growing habits of cash crops at the school's 1,400-acre research farm.
