Soft red winter wheat is unloaded from a John Deere & Co. combine harvester in Kirkland, Illinois, U.S., on Thursday, July 23, 2015. The quality of some of the first wheat harvested by U.S. farmers in 2015 is the worst in at least 17 years, according to one measure, following heavy rainfall across parts of the Midwest.
