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.
“Warmer and generally dry conditions allowed for harvest to take another big step forward, with soybeans nearing completion,” said Secretary Naig. “A significant weather system with the potential for widespread rain is expected to move through the state later this week, which could idle harvest but alleviate some of the drought conditions.”
The weekly report is also available on the USDA’s website at nass.usda.gov.
Dry and warmer than normal temperatures in Iowa this week resulted in 5.7 days suitable for fieldwork during the week ending October 22, 2023, according to the USDA, National Agricultural Statistics Service. Corn and soybean harvest continued to be the primary field activities for the week, although there were reports of fertilizer application and fall tillage.
Topsoil moisture condition rated 16 percent very short, 38 percent short, 44 percent adequate and 2 percent surplus. Subsoil moisture condition rated 28 percent very short, 43 percent short, 28 percent adequate and 1 percent surplus.
Corn harvested for grain reached 62 percent statewide, 2 days ahead of last year and 1 week ahead of the 5-year average. Moisture content of field corn being harvested for grain remained steady at 17 percent. Soybeans harvested reached 87 percent, 1 day ahead of last year and 10 days ahead of the average.
Pasture condition improved slightly to 19 percent good to excellent. Livestock conditions have been reported as generally good, while getting water to pastured cattle continued to be an issue.

Afternoon conditions were clear with southwesterly winds and high temperatures in the upper 60s and low 70s. Winds began shifting to the west as a low-pressure center propagated through Minnesota into Wednesday (18th) with morning lows holding in the 30s east to low 50s west. Light showers formed along the attendant cold front as it swept through the state in the late afternoon with temperatures holding in the upper 50s and low 60s.
