US wheat futures fell 3.7 percent on Thursday, pressured by results from a crop tour that showed yield prospects in Kansas remained above average despite a severe snow storm, traders said. A round of profit-taking also pressured wheat prices, which rallied this week to their highest in nearly two months on concerns that the storm had damaged much of the Kansas crop. Thursday's sell-off erased nearly all the gains made from the surge.

Corn futures also closed lower, under pressure from the drop in wheat as well as forecasts for drier weather in key growing areas of the Midwest. The weather outlook bolstered expectations of a pickup in the pace of planting. Soyabean futures ended in slightly negative territory, with consolidation trading noted around key technical chart points. Concerns that heavy rains in southern growing areas flooded out some fields that will have to be re-planted limited declines in soya.

Chicago Board of Trade soft red winter wheat futures for July delivery ended down 16-1/4 cents at $4.37-3/4 a bushel. K.C. July hard red winter wheat, which tracks the Plains crop, was 18-3/4 cents lower at $4.44-1/2 a bushel.

Wheat yield potential in Kansas was estimated at 46.1 bushels per acre (bpa), crop scouts on the annual Wheat Quality Council crop tour said on Thursday. That tops the tour's five-year average for the state. Much of the crop benefited from ample moisture during the growing season; the extent to which wheat was damaged by snowstorms over the weekend was unknown, the scouts said. CBOT July corn closed down 8-1/4 cents at $3.66-1/2 a bushel while CBOT July soyabeans were 1 cent lower at $9.78-1/2 a bushel.
