# BRAZIL CORN WATCH: Rains to favor planting in south, dryness concern in central region | S&P Global

> S&P Global reports that favorable rains are forecast for southern Brazil from Sept. 28 to Oct. 4, supporting first corn planting. Central Brazil faces drier weather that may delay soybean planting, with first corn planting in the Center-South at 26% of the forecast area as of Sept. 23.
