What is a common problem with grain storage facilities in Wisconsin?

• A. Rapid temperature change causing moisture condensation on cold grain
• B. Excessive sunlight
• C. Overly large ventilation
• D. High altitude

Answer: (A)

Moisture management inside grain storage is critical. When warm, humid air comes into contact with cold grain, water condenses on or inside the grain. This raises moisture content, promoting mold growth and creating conditions that pests like grain beetles and weevils thrive in. In Wisconsin, the climate often involves rapid temperature changes between cold grain and warmer outdoor air, making condensation on the grain a common problem that leads to spoilage and increased pest pressure. Excessive sunlight isn’t a typical internal problem for stored grain, overly large ventilation isn’t usually cited as the primary issue (proper airflow is important for drying but too much can waste energy or cause spoilage if not managed), and high altitude isn’t relevant to Wisconsin storage facilities.
