Soybeans are falling for a second day on expectations that Brazil will reap a bumper harvest.
May soybeans fell 21.75 cents, or 1.5 percent, to $14.47 a bushel. The drop Wednesday was the biggest this month and follows a 0.7 percent decline a day earlier.
A good harvest could propel Brazil past the United States to become the world's largest producer of soybeans.
In grain trading, corn futures also fell, dropping 4 cents, or 0.6 percent, to $7.1025 a bushel. Wheat gained 6.5 cents, or 0.9 percent, to $7.10 a bushel.
Metals all declined, with copper logging the biggest drop of 0.8 percent.
