Corn traded on B3 closed virtually stable on Wednesday, reflecting the dispute between internal and external factors that influence the market. According to TF Agroeconômica, the grain's quotes suffered small adjustments, driven by the 0.93% increase in Chicago and pressured by the 0.70% drop in the dollar. The more favorable weather in the Midwest, which allowed the advancement of the second corn planting, and the excessive rains in Paraná, which may cause punctual damage to crops, were the main elements that determined the caution of investors.
