DES MOINES, Iowa (Sept. 23, 2024) - Iowa Secretary of Agriculture Mike Naig commented on the Iowa Crop Progress and Condition Report released by the USDA National Agricultural Statistics Service. The report is released weekly April through November. Additionally, the Iowa Department of Agriculture and Land Stewardship provides a weather summary each week during this time.

"Combines are rolling in many areas of the state as fields are ready," said Secretary Naig. "Though rain this past weekend may have slowed progress for some, harvest will continue ramping up throughout Iowa. The warmer and drier outlook into early October should provide an excellent window of opportunity for many farmers."
