Iowa Crop Progress and Condition Report

Sept. 9–15, 2024

Posted

(SBA) - 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.

“The unseasonably warm temperatures and dry conditions over the past week allowed farmers to chop silage, seed cover crops, top off propane tanks, and make additional harvest preparations. There have also been reports of some harvest activity in pockets of the state, though forecasts are showing chances for widespread rainfall later this week that could temporarily park some combines,” said Secretary Naig. “National Farm Safety and Health Week is a timely reminder for all farmers and drivers to do our part to ensure a safe and productive harvest season for everyone in the field, around the farm and on the road. Given the stress and long hours of harvest as well as challenges in the ag economy, it’s also important for farmers and those involved in agriculture to prioritize their mental health and well-being.”

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