Bunge Ltd. (BG), fertilizer and oilseed producer, said it will buy Corn Products International Inc. (CPO) for $4.4 billion, or $56 a share, a 31% premium to its Friday closing price.

The purchase will help Bunge expand its product line to include Corn Products’ starches, syrups and sweeteners.

The deal will help Bunge diversify its sources of revenue with a “solid cash-flow business,” Chief Executive Alberto Weissar told Reuters. Weissar expects the deal to be closed in the fourth quarter of 2008 with a bump in earnings coming as soon as late 2009 or early 2010.

“Corn is in trouble because of the wet spring that has drenched the midwest,” says Justice Litle in Taipan Daily.

Globally, corn supplies are already straining to meet demand. America is the world’s king of corn. If our crop is going to be light, that puts corn on the launch pad.
