Pro Farmer senior market analyst Jeff Wilson is pleased with what he saw while on the Midwest Crop Tour in South Dakota. “We found a pretty darn good South Dakota corn and soybean crop.” Pro Farmer is estimating South Dakota’s corn yield at 178 bushels per acre. That’s up 20 percent from last year and up from the 170 bushel yield forecast by USDA earlier this month. “The reason South Dakota is going to have such a big crop this year is their plant populations are out of sight. It’s big; it’s like the levels you see in the Eastern Cornbelt.” South Dakota’s soybean pod counts are up almost 14 percent from last year.
