DES MOINES, Iowa (AP) — The latest crop report from the U.S. Department of Agriculture shows Iowa’s cornfields have been hit hard by the wet spring. Twelve percent of the crop is in poor condition, worse among the 18 leading corn growing states. Monday’s report says 4 percent is very poor while 34 percent is fair and 50 percent is good or excellent. Eleven percent of corn plants haven’t emerged from the ground yet and 6 percent of the crop hasn’t been planted. Normally the crop is all in by now and 99 percent emerged.

The USDA already assumes the average amount of corn expected to be harvested per acre in the U.S. to be reduced to 156.5 bushels per acre down from 158 bushels estimated a month ago.
