Leaving corn in the field over winter is becoming more than an isolated practice for some Ukrainian farms, as producers look for ways to reduce costs. During the 2025/26 season, a prolonged and rainy autumn resulted in high grain moisture and significantly delayed harvesting. By the end of December, around 15% of Ukraine's corn remained in the fields, while some farms completed harvesting only in spring 2026.
The main economic factor is the cost of grain drying. At some farms, corn moisture exceeded 25% in autumn, while grain intended for long-term storage generally needs to be dried to approximately 13–14%. Elevator drying costs reached around UAH 150–250 per tonne for each percentage point of moisture removed, excluding transportation and other expenses. As a result, some farmers left corn standing in the field, allowing it to lose moisture naturally.
However, savings on drying come with additional risks. Keeping corn in the field for an extended period increases the probability of plant lodging, ear damage, disease and losses caused by birds and wildlife, while adverse weather can make spring harvesting more difficult. Late harvesting also reduces the time available to prepare fields for the next planting campaign. In spring 2026, some Ukrainian farms were still harvesting the previous year's corn in May and preparing the same fields for planting almost immediately afterwards.
Whether overwintering corn becomes a broader trend will largely depend on the economics of individual farms. If energy, drying and logistics costs remain high and grain moisture is again elevated at harvest, more producers may consider this approach. However, it should be viewed primarily as a cost-driven strategy rather than a new production technology: potential savings on drying must be weighed against the risk of yield losses and deterioration in grain quality.
