Today in the grain market, Soybean futures traded lower, pressured by expected rainfall in Brazil and Argentina, which kept the market in a four-week sideways pattern. Corn futures, however, firmed up, following crude oil prices higher amid stalled geopolitical talks with Iran, while emerging drought conditions in the corn belt also offered support. Meanwhile, Wheat futures posted solid gains as drought in the hard red winter wheat states continues to expand, allowing prices to rebound from Friday's lows despite non-commercial traders holding net short positions.
