Imea says soybean planting in Mato Grosso is about 90% complete, improving the prospects for planting 2026/27 second-crop corn within the preferred window. It maintains its corn area estimate at 7.48 million hectares, up 0.59% year over year, and cites growing domestic demand; weather during the crop cycle remains a risk, despite forecasts for potentially favorable rainfall from November through February.
Timely soybean planting may enable more corn to be sown in the ideal second-crop window, supporting production and weighing on corn prices if yields are favorable. Weather risks could limit that supply increase.
