Sixty-four percent of Iowa’s corn lay in seedbeds as of May 6. This is 6 percent ahead of normal (see USDA report). Northeast and South Central cropping districts reported 50 percent planted while the Northwest and West Central cropping districts were around 75 percent planted. Indeed many farmers completed planting corn; 7 percent of our soybeans were planted – slightly behind the 11 percent five-year average.
