The announcement is being made at a late-morning news conference at Coca-Cola's juice production plant in Auburndale. Details were released in advance to The Associated Press.
Coca-Cola owns the Minute Maid and Simply juice brands.
"It's an investment in a market that's very important to us," said Steve Cahillane, the president of Coca-Cola Americas.
Some 5 million new trees will be planted in the new groves, believed to be the largest citrus addition in the state for at least 15 years. The groves will be located in Polk, DeSoto and Hendry counties in central Florida.
Company officials say the new groves and resulting juice production are expected to add about 4,100 jobs to Florida's economy.
The move also is seen as a boost to historically declining acreage devoted to citrus production in Florida. During the state's past housing boom, many citrus farmers sold their land to developers. Since 1997, total citrus acreage has fallen by 25 percent, from 600,000 acres to 450,000 acres, because of the disease, pests and other pressures, according to Florida Citrus Mutual.
Coca-Cola officials said that the Florida Citrus Commission is working on an economic study centered on the company's investment, and that a preliminary draft shows that over the course of 25 years the expansion will add more than $10.5 billion - or $422 million per year - to Florida's economy. Company officials said Coca-Cola buys a third of all Florida oranges.
Coca-Cola reported its first-quarter results in mid-April; they topped Wall Street expectations as sales volume rose in emerging markets. Shares of Coca-Cola Co. rose nearly 6 percent to $42.37 and touched their highest point since the late 1990s.
Cahillane said that the company also purchases juice from Brazil, Florida's biggest competitor in the juice industry. He said that different harvest times in each location allow the company to give customers "consistent, great tasting juice." About 90 percent of Florida's oranges are used for juice; by contrast, the majority of California's orange crop is sold as fresh fruit. Florida is second in the world for orange juice production, behind Brazil.
Under the program, two Florida growers will each plant 12,500 acres.
Bill Becker, president of Peace River Citrus Products in Vero Beach, is one of the growers. He said the new trees will be planted on land that once held citrus groves or on lands that are currently idle.
"It's a big help to the entire industry and to the state, for that matter," said Becker, adding that the research being done in Florida about the deadly citrus greening disease has bolstered the company's confidence in the long-term health of the state's citrus industry.
"Without some of the research that we're conducting now, they'd probably be less enthused about planting," he said.
Becker said he hopes that Coca-Cola's investment will reverse the trend of declining citrus acreage in Florida.
The state's citrus crop suffered huge losses this past season due to warm, dry weather, too much fruit on each tree and citrus greening disease.
According to the Florida Citrus Mutual, the citrus industry directly and indirectly contributes some 76,000 jobs in Florida.
