DES MOINES, Iowa – Iowa Secretary of Agriculture Mike Naig commented today on the Iowa Crop Progress and Condition Report released by the USDA National Agricultural Statistics Service. The report is published weekly from April to November.

“A cold breeze late last week caused temperatures to drop well below normal as the first rain showers of the season swept over nearly fully harvested corn and soybean fields,” Minister Naig said. “Farmers are focused on completing field work in the fall before the frost sets in as forecasts show colder conditions by the end of November.”

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

crop report

Harvest was mostly complete, with 5.6 days suitable for field work in the week ended November 13, 2022, according to the USDA, National Agricultural Statistics Service. Fieldwork included packing fall tillage, applying fertilizer, pressing stalks, and hauling and spreading manure.

The moisture status of the topsoil was rated at 18 percent as very low, 35 percent as too low, 45 percent as sufficient and 2 percent as excessive. The subsoil moisture is rated at 25 percent very low, 38 percent low, 36 percent sufficient and 1 percent excess.

Corn harvest for grain harvest was 95 percent complete, eight days ahead of last year and 12 days ahead of the average. The moisture content of field corn harvested for grain was 16 percent. Farmers in northeast and south-central Iowa still have over 10 percent of their grain crop corn that has yet to be harvested.

Livestock were mostly fine, although the sudden move to colder temperatures caused some stress.
