CBOT soybean futures fell for the fourth time in five sessions, weighed down by an outlook for dry weather in the U.S. Midwest that will foster development of recently seeded crops. soybean export sales were in a range from 200,000 to 550,000 tonnes (old-crop and new-crop combined) in the latest reporting week. A week ago, soybean export sales totaled 478,741 tonnes.
