Another week of cool but not too cold weather has positioned the Iowa grain crop well for the final run to harvest. During the week of August 17 we lost a net 50 to 60 degree days to average, but favorable night temperatures allowed for crop condition to improve slightly. The August 24 USDA crop condition report assesses Iowa corn and soybean both at 79 percent good to excellent. Another two or three weeks of good weather and we will begin the final dry-down push to harvest.
