Iowa Crop Progress and Condition Report
July 8 – 14, 2024
DES MOINES, Iowa (July 15, 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.
“Although the first half of July was cooler and wetter than average, Iowa’s tasseling corn encountered some summer heat and humidity this past weekend,” said Secretary Naig. “Monday’s thunderstorms will give way to more seasonal conditions and cooler temperatures. This will be welcome news for our state’s livestock as well as those participating in county fairs around the state.”
The weekly report is also available on the USDA’s website at nass.usda.gov.
