**DowDuPont chairman Andrew Liveris will step down, ending a career that saw him rise through the ranks of Dow Chemical to CEO and orchestrate the world’s largest chemical industry merger with DuPont Inc.

The 63-year-old will relinquish the title on April 1 and remain on the board thru July 1.

With DowDupont splitting into three separate businesses, current COO Jim Fitterling will assume the CEO seat of the new materials company.

**The USDA left its production estimates for this year’s corn and soybean crops unchanged from February forecasts, while raising its projection for U.S. corn-ethanol output and slashing its outlook for Argentina’s soybean harvest.

The corn crop will come in at just over 14.6 billion bushels. That’s unchanged from the month-ago estimate and down from the record 15.148 billion bushels harvested last year.

According to Agri-Pulse, estimated ethanol use was raised 50 million bushels, or 38 percent of the total crop.


**Another high-profile athlete has tested positive for a banned PED, before blaming his positive test on contaminated beef.

This time, it’s middleweight boxer and former 154-pound world champion Canelo Alvarez who tested positive for the banned drug clenbuterol.

Alvarez joins a list of other athletes who also tested positive for clenbuterol, most notably Tour de France champion Alberto Contador in 2010.

In Contador’s case, however, his explanation didn’t fly. He was stripped of his Tour title and suspended for two years.
