Argentina's Rosario grains exchange cut its 2026/27 soybean harvest estimate by 200,000 tons to 47.8 million tons on Wednesday citing lower profit margins relative to corn that are drawing farmers to expand corn plantings, [reported Reuters](https://www.reuters.com/world/americas/argentinas-corn-exports-set-record-war-ukraine-european-heat-wave-reshape-trade-2026-09-09/?ref=news.cibocom.com).

The exchange raised its 2026/27 corn harvest forecast to between 67.5 million and 70.5 million tons from 66 million, while lifting its wheat output estimate by 2.4% to 21 million tons.

"When comparing margins, corn is starting to gain acreage from soybeans," the exchange said in its monthly crop report.

Corn planting in Argentina begins in the coming weeks; soybean planting starts in October.

Wheat planting has already finished, with the harvest beginning in November; the exchange cited good crop conditions for the upgrade.

Argentina is the world's top exporter of soybean oil and meal, and the third-largest exporter of corn.
