Chicago | Reuters — Forecasts for rain in the U.S. Midwest pushed corn and soybean futures lower on Tuesday, traders said.
New-crop December corn, which tracks the crop that farmers will harvest in the fall, notched the biggest decline. The contract sagged 3.2 per cent as the storms are expected to provide a much-needed boost to soil moisture just as the crop enters its key development phase.
“It has been very dry but dryness in the early stages that we have been in is much less meaningful than dryness in pollination that is coming up here in the next couple of weeks,” said Ben Buie, grain team leader at MaxYield Cooperative. “We are really hitting the crucial time.”
