Due to the cool and wet conditions, soybeans harvested at this time of the year will need to be dried on the farm or at the elevator. Some elevators will accept soybeans up to 18 percent moisture while others will reject loads that are above 15 percent moisture. Contact your elevator prior to delivery and understand their discount schedule. Information on understanding soybean discount schedules is available in “Understanding soybean discount schedules” from Michigan State University Extension.
Commodity soybeans used for domestic crush or export can be dried using supplemental heat. However, food grade and seed beans should not be dried with supplemental heat. Proper management is essential to minimizing damage when using supplemental heat. Keep the drying temperature below 120 degrees Fahrenheit.
