Producers surveyed across 29 states indicated a move back to more corn planted acres after soybeans led the way last year. Allendale Inc. conducted the annual survey Feb. 25 to March 8 and included clients and non-clients through phone calls, the company’s website and other media. “We saw a record participation this year, and had a strong survey sample for the top 12 states that covers roughly 83 percent of U.S. acreage,” said Rich Nelson, Allendale chief strategist.
