USDA raised its forecast for 2017 corn and soybean yields on Sept. 12. But farmers reporting Feedback From The Field last week headed in the other direction, cutting production estimates due to a stressful growing season ending in some areas with drought and disease pressure.

After increasing yield estimates consistently for a month, producers slashed their outlook for both crops. Even those reporting potential for 200-bushel corn are concerned.

“Crops continue to lag and soybeans are getting smoked by white mold issues,” said a grower southwest of Minneapolis who lowered yield estimates. Though his corn was at 205 bpa, soybeans were only 45 bpa, well below USDA nationwide average of nearly 50 bpa.

“Late season dryness is hurting soybeans and affecting test weights in the corn,” reported a southern Wisconsin farmer looking for 200 bushel corn and 50 bushel beans.

Other producers in northern states were worried about late maturity after a cool August.

“Even 99-day corn is only about half milk line with a May 6 planting date,” reported a southwest Minnesota farmer looking at 218 bushel corn and 64 bushel soybean who was also concerned about white mold. “I feel the top end of yields has been taken off.”

Frost is a concern in Nebraska, where a cold snap already took temperatures in a few areas below freezing. The shift from a wet start to dry weather in the second half of the growing season has left some producers in the eastern Corn Belt looking at poor crops for another year.

“Since May floods only two-thirds of normal rain,” posted a farmer from northeast Indiana.” Much of April planted corn is only 50% milk line. Thus, 2 to 3 weeks behind schedule. Soybeans have done very little the last 2 weeks as far as filling pods due to cold nights and lack of rain. “

Another Hoosier north of Indianapolis said corn has caught up in height but will be hurt by slow development early, estimating yields at only 130 bpa: “The yield limit was set for the corn, back when the corn was having a hard time growing. We can't get that back.”
