Published on: Oct 1, 2013

About 5% of Iowa's 2013 corn crop had been harvested as of September 29, according to the latest weekly USDA survey, released September 30. Harvest progress in Iowa is running two weeks behind normal. This time last year, about half of Iowa's corn acres had been harvested. The state's 5-year average is 16%.

The latest survey rates 37% of Iowa's corn crop and 34% of the soybeans in good to excellent condition. Moisture content of corn harvested last week was estimated at 23%, while corn still in the field was estimated at 28% moisture. Nationally, based on surveys of the 18 largest corn growing states, about 12% of  the U.S. corn acres were harvested as of September 29, 2013.

HARVEST STARTING TO PICK UP PACE: Mostly dry weather this past week allowed harvesting of corn and soybeans to both reach 5% complete in Iowa, the latest USDA survey shows. Thats well behind the pace of a year ago. This time last year at end of September, about half of Iowas corn acres and half of Iowas soybean acres had already been harvested.

For soybeans, the survey shows 5% of Iowa's bean acres were harvested by the end of last week. That compares to 50% by that date a year earlier. The survey shows 88% of Iowa soybean leaves had turned color, about 8% behind normal for the end of September. Nationally, 11% of the U.S.'s 2013 soybean acres had been harvested as of September 29.

Pace of harvest will likely continue to pick up, as warm dry weather helps this year's crop dry down in the field

"Harvest is starting to pick up speed with 5% of both the corn and soybean crop now out of the field. Early reports from farmers show yields vary widely across the state," notes Iowa Secretary of Agriculture Bill Northey. "It is likely the pace of harvest will continue to increase as warm dry weather has helped the crop dry down in the field."~~~PAGE_BREAK_HERE~~~
