DES MOINES, Iowa—Iowa Secretary of Agriculture Mike Naig commented Tuesday on the Iowa Crop Progress and Condition Report released by the USDA National Agricultural Statistics Service. The report is released weekly April through November.
“The weather could not have been better for Farm Progress Show attendees last week as exhibitors highlighted and demonstrated the latest innovations across the ag sector,” said Iowa Secretary of Agriculture Mike Naig. “Now that we are past the Labor Day holiday and the days of summer dwindle, farmers are keeping a close eye on outlooks in preparation for harvest. With the potential for warm and dry conditions through fall, we need to remain vigilant for potential fire hazards as combines start to roll.”
The weekly report is also available on the USDA’s website at nass.usda.gov.
