Iowa Crops and Weather Report – Oct. 9

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

“This run of extremely wet weather has slowed harvest progress dramatically and as a result soybean harvest is now well behind the five-year average. We need the rains to stop and several days of dry weather so fields can dry and farmers are able to get back to harvest,” Naig said.

The weekly report is also available on the Iowa Department of Agriculture and Land Stewardship’s website at or on USDA’s site at The report summary follows here:


Continued wet weather conditions allowed Iowa farmers just 1.6 days suitable for fieldwork during the week ending October 7, 2018, according to the USDA, National Agricultural Statistics Service. Activities for the week included harvesting corn and soybeans when weather permitted.

Topsoil moisture levels rated 0 percent very short, 0 percent short, 41 percent adequate and 59 percent surplus. Subsoil moisture levels rated 1 percent very short, 2 percent short, 50 percent adequate and 47 percent surplus. Recent rains have boosted topsoil moisture supplies in south central and southeast Iowa to 99 percent adequate to surplus.

Ninety-five percent of the corn crop was mature, 9 days ahead of average. Fifteen percent of the State’s corn for grain has been harvested, 10 days ahead of last year. Farmers in southeast Iowa continue to lead the way with 39 percent of their corn for grain harvested. Moisture content of field corn being harvested was at 20 percent. Corn condition rated 70 percent good to excellent. Nearly all of the soybean crop was coloring with 94 percent dropping leaves, 8 days ahead of average. Eighteen percent of the soybean crop has been harvested, 5 days behind the average. Soybean condition rated 70 percent good to excellent.

The third cutting of alfalfa hay was nearly complete at 98 percent. Pasture condition improved slightly to 55 percent good to excellent. Muddy feedlot conditions have been a challenge for cattle producers.
