The U.S. Department of Agriculture said Tuesday virtually all the corn is planted in Iowa and 90 percent of the plants have emerged from the dirt, about five days ahead of average.
Iowa's soybean planting is 10 percentage points ahead of normal with 88 percent planted.
Nebraska's corn crop is at 96 percent, near the five-year average and soybean planting is at 73 percent, behind the average of 82 percent.
