MU Soybean Monitoring Report Predicts Sharp Decline in Yield

The latest Soybean Growth Monitoring Yield Prediction report from University of Missouri Extension predicts drastic shifts to lower soybean yields due to a lack of rainfall.

MU Extension soybean agronomy specialist Andre Reis says the latest yield predictions have averaged 3-6 bushels per acre lower than in the previous report.

“August 2025 was the second-driest August on record, with only 0.79 inches of statewide average rainfall,” says Zachary Leasor, MU Extension state climatologist.

According to Leasor, the U.S. Drought Monitor map for Missouri released on Sept. 4 shows that 93.68% of Missouri is at least abnormally dry following an unusually wet spring. The southeastern and southwestern parts of Missouri are hardest hit, but the rest of the state except for northwestern Missouri is showing emerging signs of drought.
