Iowa Crop Progress and Condition Report

September 26 – October 2, 2022

DES MOINES, Iowa (October 3, 2022) — 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 released weekly April through November.

“Iowa farmers are moving full speed ahead with corn and soybean harvest across the state,” said Iowa Secretary of Agriculture Mike Naig. “Though portions of northern Iowa received its first widespread freeze last week, drier and warmer conditions are expected to persist for the foreseeable future and farmers should remain vigilant about combine and field fire risks.”

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

Daytime temperatures varied from the low 60s north to low 70s southwest with pockets of partly cloudy skies in western Iowa. Variable winds developed through the nighttime hours with thicker cloud cover over much of the state; eastern Iowa remained clear as low temperatures statewide hovered in the upper 30s to mid 40s where clouds were present. Tuesday (27th) was a mirror-image day, though winds shifted to a northerly direction through the morning hours. Daytime conditions were clear, and temperatures remained in the upper 60s and low 70s.
