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.
“Corn and soybean harvest is beginning to wind down thanks to more agreeable weather, though there is still plenty of farm and field work left to finish up yet this fall,” said Secretary Naig. “While statewide drought remains a concern heading into the 2024 growing season, the bursts of October rain helped improve soil moisture in parts of northwestern and eastern Iowa.”
The weekly report is also available on the USDA’s website at nass.usda.gov.
