DES MOINES, Iowa—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.
“Iowa farmers made significant progress in the field last week thanks to several consecutive days of warm and windy weather conditions,” said Secretary Naig. “This week’s forecast calls for cooler temperatures and several chances of rain showers, which may cause farmers to pause field work for a few days. We need the moisture across the state, and the widespread rainfall will give the recently planted corn and soybeans a good boost.”
The weekly report is also available on the USDA’s website at nass.usda.gov.
