Potato and onion storage warehouses are special facilities designed to preserve these crops under suitable conditions after harvest to prevent spoilage. In these warehouses, environmental factors such as temperature, humidity, and ventilation are carefully controlled. This helps prevent sprouting, rotting, or drying out of the products. By keeping potatoes and onions fresh for a longer period and ensuring their steady supply to the market, these storage facilities reduce food waste and help maintain the balance between producers and consumers.
