Iowa Farmers Welcome A Week Of Drier Weather

Iowa Farmers Welcome A Week Of Drier Weather

Less rain lets farmers get into fields to replant crops, spray weeds and cut hay during week ended July 13.

Much of this year's corn crop in Iowa is now tasseling and silking, or soon will be. "In a number of fields in central Iowa, pollination will be occurring this week. And with lower than normal temperatures and low humidity forecast, pollination should be good," observes Mark Johnson, an Iowa State University Extension field agronomist. "The soil moisture supply is certainly favorable."

POLLINATION BEGINS: USDA's weekly survey shows 26% of Iowa's 2014 corn crop was silking as of July 13. That's way ahead of last year and slightly ahead of 5-year average for the state. Last week's drier weather allowed farmers to get back into fields and spray weeds.

Many farmers were unable to spray for weeds in June, given the excessive rain. The state averaged 9.96 inches of rain for the month, making it the third wettest June on record in Iowa. "The drier weather last week was very welcome as it allowed farmers to start getting back in the fields to get needed work done," says Iowa Secretary of Agriculture Bill Northey. "Much of the crop in Iowa remains in good to excellent condition, even as some of the damage from the extremely wet weather and strong storms earlier in the growing season was becoming even more apparent."

Iowa corn and soybean crops are generally doing quite well
Iowa's corn crop rates 76% good to excellent, and soybeans are 73% good to excellent, according to the weekly statewide survey based on conditions as of July 13. The survey is conducted by the Iowa office of USDA's National Ag Statistics Service. Nationally, the U.S. corn crop improved slightly this past week to a rating of 76% good to excellent, while soybeans remained at 72% good to excellent.

The complete weekly Iowa Crop Progress & Weather report is available on the Iowa Department of Agriculture & Land Stewardship's site or on USDA's site.  The report summary follows here:

Soybeans are also making good progress in the state. The survey showed 45% of Iowa's soybean acreage was blooming, 11 days ahead of the previous year and slightly ahead of normal. Six percent of the soybean crop was setting pods, 11 days ahead of last year and one day ahead of normal. And 73% of the 2014 Iowa soybean crop was rated in good to excellent condition on July 13, unchanged from the previous week.
