YIELDS ARE BETTER, PRICES TERRIBLE: “Our corn yields turned out better than expected,” says Nick Butler, Hamilton County, Iowa. “Only down about 10% from our five-year average. But with terrible prices for corn and beans, we may only break even this year.”

Iowa’s 2017 harvest heading for finish line

Weekly estimate shows 92% of Iowa corn and 98% of soybeans are now harvested.

USDA’s latest weekly statewide survey shows Iowa’s 2017 corn harvest is 92% complete as of Nov. 19, about 4% behind the five-year average. Soybean harvest is 98% finished, 1% behind normal for this date.

Farming in Lucas County in south-central Iowa, Curt Snyder finished harvesting his last 80 acres of corn on Nov. 17. That field averaged 82 bushels per acre, with a grain moisture content of 17.5%. “My neighbor only averaged 75 bushels per acre this year on corn for his entire 250 acre farm,” says Snyder. “We were hit pretty hard by summer drought in this part of the state. Another neighbor harvested yields as high as 120 bushels per acre on a field of good soil that was fortunate to be under a lone rain cloud at the right time.”

Nation’s corn harvest set to wrap up
The U.S. 2017 corn harvest is also set to wrap up, running 5% behind normal. As of Nov. 19, USDA pegged the nation’s corn harvest at 90% complete, compared with a 95% five-year average. The U.S. soybean harvest, meanwhile, is 96% finished, slightly behind a five-year average of 97%.

“Harvest progress continued across much of Iowa last week with some farmers finishing combining and completing other fall fieldwork, including construction of conservation practices,” notes Mike Naig, Iowa deputy secretary of agriculture. “There is still harvest work to be done across the state, especially in northeast, southwest and south-central Iowa where 15% of this year’s corn is still in the field.”

The complete weekly crop and weather report is available on the Iowa Department of Agriculture and Land Stewardship website IowaAgriculture.gov or on USDA’s site nass.usda.gov/ia. The report summary follows.

Summary of Iowa crop conditions
Minimal precipitation allowed Iowa farmers to make progress toward completing harvest with 5.5 days suitable for fieldwork during the week ending Nov. 19, according to USDA’s National Ag Statistics Service. Activities for the week included harvesting, baling cornstalks, tiling, hauling and spreading manure, applying fertilizers, and planting cover crops.

Topsoil moisture levels for a statewide average rated 3% very short, 9% short, 84% adequate and 4% surplus. Subsoil moisture levels rated 6% very short, 16% short, 76% adequate and 2% surplus.

Iowa’s 2017 corn crop 92% harvested

The survey shows 92% of Iowa’s 2017 corn crop has been harvested, eight days behind last year and 8 days behind the five-year average. Moisture content of corn being harvested for grain averaged 17% this past week. Only northeast, southwest and south-central Iowa have more than 10% of their corn crop remaining to be harvested.

There were reports of limited stress on livestock; however, fluctuations in temperatures caused lung issues in some calves. Cattle continue to graze in harvested fields with limited hay being fed.

Weather summary for Iowa
Harry Hillaker, state climatologist, Iowa Department of Agriculture and Land Stewardship, provides the following summary for the week ended Nov. 12.

There were two episodes of light rain during the week, with both events bringing the greatest rain amounts over the east and the least over the far northwest. Light rain fell over about the southeast three-fourths of the state on Nov. 14 during the night and into the morning of Nov. 15. Keosauqua in southeast Iowa reported the most rain with 0.27 inch. Rain fell nearly statewide between the morning of Nov. 17 and the morning of Nov. 18. A maximum of 0.83 inch of rain was reported at Keokuk in Iowa’s southeast corner.

Total rainfall last week half of normal
