Prices for grains and soybeans continue to climb as crops wilt in summer heat across the nation's farmland.
Corn gained 3.3 percent Monday to finish at $6.5575 per bushel. Wheat and soybeans also rose.
Prices for all three are surging on expectations that the hot, dry weather will cut supplies after the harvest. At the same time, global demand remains strong.
Other commodities are mostly lower after a new report concluded U.S. manufacturing production declined in June for the first time in nearly three years. And China's manufacturing grew in June at its slowest pace in seven months.
Prices for gold, silver, copper and oil are lower. Platinum is higher, and natural gas is unchanged.
