USDA will update its planted area estimates in June – and the Chicago-based research and brokerage firm Linn Group expects the numbers for corn, soybeans and wheat will be down. That’s because of the weather issues that have plagued major growing regions of the U.S. The group no longer believes the nation’s corn growers will plant 92.2-million acres – but 89.5-million. But that doesn’t mean growers will abandon corn for soybeans. The Linn Group is forecasting a decline in soybean acreage to 75.1-million. They peg spring wheat planting at 14-million – down from USDA’s 14.4-million projection.
