CHICAGO: US corn and soyabean futures eased on Tuesday as weather forecasts looked less threatening to America's crops than they had a day earlier, analysts said.
Traders took profits after soyabean futures reached a four-month high on Monday on concerns that hot, dry conditions could threaten crop yields in the US Midwest. Rain now appears more likely later this week and next week, according to Commodity Weather Group.
The markets are paying close attention to weather forecasts because corn is entering a critical stage for crop development. Yields are important because the US Department of Agriculture last week estimated that farmers planted fewer acres than analysts expected.
"The weather forecast is not quite as dire as some had thought yesterday," said Tomm Pfitzenmaier, analyst for Summit Commodity Brokerage in Iowa.
Chicago Board of Trade most-active December corn ended down 3-3/4 cents at $3.52-1/2 per bushel. Most-active November soyabeans closed down 3-3/4 cents at $9.02-1/2 a bushel.
After Monday's market close, the USDA rated 71% of the US soyabean crop as being in good-to-excellent condition, unchanged from the previous week and above analysts' expectations for 70%. The agency said 71% of US corn was in good-to-excellent shape, compared to 73% last week and 72% expected by analysts.
"The USDA's crop conditions report said US corn and soyabeans are looking reasonable with no reason today for extra concern about crops," said Matt Ammermann, StoneX commodity risk manager.
Bucking the lower trend in corn and soyabeans, most-active CBOT wheat ended 2 cents higher at $4.95-1/4 per bushel. Some traders were buying wheat and selling corn in spread trades, an analyst said.
France's farm ministry forecast the French soft wheat harvest would fall nearly 21% this year to 31.3 million tonnes. IKAR, one of Russia's leading agriculture consultancies, cut its estimate for the Russian wheat crop by 1.5 million tonnes to 78 million tonnes.
