Mosaic Co., the world’s largest phosphate-fertilizer producer, agreed to acquire a mine and other assets from CF Industries Inc. for $1.2 billion to boost its output of the crop nutrient in Florida.

Mosaic will also pay $200 million to fund CF’s asset retirement obligation escrow, Plymouth, Minnesota-based Mosaic said in a statement Monday. Mosaic said the deal will add about 30 cents a share to 2015 earnings, excluding any debt financing costs and increase in the number of the company’s shares.
