Iowa Crop Progress and Condition Report

Aug. 19-25, 2024

DES MOINES, Iowa (Aug. 26, 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.

"With the Farm Progress Show kicking off in central Iowa, much of the state will receive a blast of heat followed by cooler weather as we head into September," said Secretary Naig. "This stretch of unseasonably dry conditions is providing a nice window for farmers to bale hay, chop silage and begin to seed cover crops."

The weekly report is also available on the USDA's website at nass.usda.gov.
