DES MOINES – Iowa Secretary of Agriculture Bill Northey today commented on the Iowa Crops and Weather report released by the USDA National Agricultural Statistical Service. The report is released weekly from April through October.

“We continue to move closer to harvest with ten percent of corn reaching maturity and five percent of soybeans dropping leaves. Some farmers are starting to chop corn for silage and harvest seed corn fields,” Northey said. “Unfortunately, the strong storms that have rolled through the state have caused some flooding damaged and left crops underwater in some areas.”

The weekly report is also available on the Iowa Department of Agriculture and Land Stewardship’s website at or on USDA’s site at The report summary follows here:


Iowa farmers took advantage of the 4.9 days suitable for fieldwork to finish oat harvest, chop corn silage, and start seed corn harvest during the week ending September 6, 2015, though scattered but heavy showers kept some fields too wet to work, according the USDA, National Agricultural Statistics Service. Corn for grain continues to mature. There were some reports of pressure on corn from disease.
