# Early-planted Corn Yield Losses Possible as Drier Pattern Sets In

> A La Nina pattern is bringing drier-than-normal conditions to Argentina and Brazil. Southern Brazil from São Paulo to Rio Grande do Sul had its 7th to 9th driest first half of November in 30 years, and dryness is expected to continue. Early-planted crops entering December pollination face yield risk.
