Brazil's second corn harvest for 2023/2024 is projected to be significantly lower than initially expected, with an 11% reduction to 118.5 million tons. This is due to a decrease in planted area, reduced investment by farmers, and adverse El Niño weather conditions. The drop in production could potentially dethrone Brazil as the world's largest corn exporter, with exports predicted to fall from 56 million tons to 35 million tons.
