BUENOS AIRES, ARGENTINA — A riverbank collapse along the Parana River has reduced grain cargo shipments to Argentina’s Port of Rosario, according to a Reuters report.

Dredgers are reportedly working just south of the Rosario complex to restore the necessary depth of water for export traffic. No estimate of when normal operations would resume was given, according to Reuters.

Guillermo Wade, manager of the Chamber of Port and Maritime Activities, told Reuters: “A ship usually carries about 50,000 tonnes of grain. You are looking at about 11,000 tonnes less per boat.”

Argentina is one of the world’s biggest soybean, soy meal and corn exporters. Last year it ranked third in both corn and soybean shipments.

The Rosario port ships about 80% of Argentina’s agricultural exports.

Low water levels already were hampering export traffic prior to the riverbank collapse as the water level on the Parana River had fallen to a 50-year low, Reuters reported.
