Even before this heat wave, Iowa crops were not doing well.
The latest crop report from the USDA shows less than a third of Iowa’s top soil has adequate moisture. Just 45-percent of the soybean crop and 44-percent of the corn crop have a rating of good-to-excellent.
Iowa Secretary of Agriculture Bill Northey says he expects those numbers will get worse.
“Crop conditions continue to decline and that trend is likely to continue with the extremely warm weather that is being forecast for the week ahead,” Northey said. “Hot temperatures and dry soils can hurt yields on both corn at soybeans at this point of the season.”
