For winter storage, store commercial soybeans at 13 percent moisture or less. Aerate the stored soybeans to maintain grain temperature at 35 to 40 degrees F in winter and 40 to 60 degrees F in summer. Check the bins regularly for heating or spoilage. When drying soybeans in high or low temperature dryers, be careful. Soybeans are fragile and can be damaged by air that is too hot or too dry, as well as by rough handling.
Greater airflow means faster drying.
Soybeans less than 15 percent moisture can be dried with bin fans. More detailed information on soybean drying and storage can be obtained from ISU Extension publication PM-1636. The transition from summer into winter provides a greater challenge to control PRV because of cooler temperatures and less sunlight. Maintain your vaccination and bio-security program. Each operation must test for PRV every 6 months.
