Open-air sun drying

Open sun drying generally means spreading grain on the ground in a yard or leaving cut grain in the field. In some cases, grain is spread on a tarp or mat, which can reduce losses. Open sun drying is the least resource-and-cost-intensive method of drying and is suitable for small batches. However, weather conditions can sharply limit the effectiveness and safety of open sun drying.
