Illinois experienced an erratic 2025 planting season, with wind, heavy rain in the south, and late planting that pushed some acres into June. Cool, wet conditions also caused poor soybean germination, crusting, and replanting, and cutworm pressure was high.
Late planting, replants and lower final stands in Illinois suggest weaker local yield potential for corn and soybeans, which is a modest supportive factor for prices.
