Potato tubers are considered cold-resistant vegetables, and they thrive best in storage conditions with temperatures between 0°C and 4°C. Traditionally, deep wells have been used for storage because their internal temperature and humidity remain relatively stable. However, this method can lead to early sprouting of seeds, which results in nutrient loss and reduced quality of the parent tubers. Another common method is using storage trenches, but this approach is problematic due to fluctuating ambient temperatures. If the trench is too deep, it can be prone to heat damage, causing the potatoes to sprout or rot. Additionally, there's a risk of freezing during colder periods, leading to further seed loss.
Therefore, using an empty house for winter storage is a more effective and reliable option. Here’s how it works: After sorting the potato seeds, remove any diseased or damaged tubers, and place the healthy ones into nylon bags, each weighing around 20 to 30 pounds. Stack the bags in the empty house, with a height of 1.5 to 2 meters. Make sure the stacks are kept at least 30 cm away from the walls to avoid cold damage. Place containers filled with water in the center of the room. As winter progresses and the temperature drops, when you notice frost forming on the surface of the water, cover the area with blankets to provide additional warmth.
A thermometer should be hung inside the room to monitor the temperature, and the thickness of the blankets can be adjusted accordingly. During the coldest months, hang curtains on the doors and windows to block out the cold air. This method requires minimal investment, is easy to manage, and significantly reduces seed loss, making it an ideal solution for small-scale farmers looking for a simple and effective way to store their potato harvest through the winter.
