Drought in Argentina worsens corn and soybean crop prospects

A lack of rainfall forecasted for January in Argentina’s main corn-growing regions could negatively affect grain yields in the 2025/26 marketing year. According to the weekly forecast from the Buenos Aires Grain Exchange, key agricultural areas are expected to receive only 10–25 mm of rain over the next seven days.

The Rosario Grain Exchange, which predicts a record Argentine corn harvest of 62 million tons, also noted unfavorable weather conditions over the past month following above-average rainfall in 2025. “This is an unfortunate turn in the rainfall pattern, creating certain difficulties, especially for early-planted corn,” the exchange stated in its monthly report.

Additionally, the Buenos Aires Grain Exchange reported that soybean crops in the country are also at risk due to the limited forecasted rainfall. This could impact the expected harvest and soybean supplies for both domestic and international markets.

As of the reporting period, Argentine farmers have sown 93.9% of the projected 17.6 million hectares of soybeans for the 2025/26 season and 91.7% of 7.8 million hectares of corn, according to exchange data. Nevertheless, the rainfall deficit poses additional risks to the productivity of the country’s key crops.
