Farmer and philanthropist Howard G. Buffett is set to announce on Thursday a new program to encourage farmers to donate crop revenue to help combat hunger in the rural Midwest, The Wall Street Journal reports.

The Invest an Acre program, which will receive up to $3-million from Mr. Buffett’s foundation, will urge farmers to set aside cropland and contribute the revenue it generates to Feeding America, the country’s biggest hunger charity. The organization would in turn filter the money to its affiliate food banks in the donors’ communities.

The $225-million foundation has primarily financed agricultural development abroad. Mr. Buffett, the son of billionaire philanthropist Warren Buffett, said the new effort “has the potential to engage U.S. farmers in the issue of hunger at a scale that’s never been done before.”

Agribusiness giant Archer Daniels Midland will promote Invest an Acre with the 80,000 farmers with which it works. The firm is based in central Illinois, where Mr. Buffett owns and works nearly 4,000 acres of farmland.
