Iowa has 83% of corn and 30% of soybeans planted

Weekly USDA survey as of May 10 shows farmers in Iowa remain ahead of 5-year average

The entire state of Iowa saw at least some precipitation over the past week. As a result, planting progress was slowed, especially when compared to the previous week. "Fortunately, we remain ahead of the 5-year average with 83% of the state's 2015 corn and 30% of the soybeans now planted," says Bill Northey, Iowa Secretary of Agriculture. That's according to USDA's weekly survey results, which were gathered as of May 10. The results were analyzed and released by USDA on May 11.

PLANTING PROGRESS: Corn planting in Iowa increased to 83% completed as of May 10, up from 68% the previous week. Corn planting in U.S. rose to 75% done, up from 55% a year ago at this time and well ahead of the 57% average.

"In the nine counties I cover in central Iowa, corn planting is very nearly done," says Mark Johnson, Iowa State University Extension field agronomist. "I'm guessing 98% completed now. This morning I was in a field of corn already in the V2 growth stage. I was also in another field, which was V3 growth stage corn. I'm seeing many fields of corn in the V1 to V2 development stage as of May 11. I haven't seen any insect or disease problems, nor have I gotten any calls for them either."

Scout early-planted soybeans for signs of bean leaf beetle
Early planted soybean seed with no insecticide seed treatment needs to be scouted for bean leaf beetle, says Johnson. The overwintering generation seeks out early planted beans first. These adult beetles are strongly attracted to soybeans and will move into fields with newly emerging plants.

Fields where beans emerged first should be monitored now. This generation of bean leaf beetles usually doesn't cause economic damage, he says. But occasionally it does. And the beetles can vector bean pod mottle virus. Also, their presence indicates potential for later generations of the beetles reaching economic threshold levels.

Wet weather slowed planting in Iowa for week ending May 10
The complete weekly Iowa Crop Progress & Weather Report is available on the Iowa Department of Agriculture & Land Stewardship's site www.IowaAgriculture.gov or on USDA's site www.nass.usda.gov/ia. The report summary follows here:

CROP REPORT: After the previous week's near-record corn planting in Iowa, wet weather hindered spring planting during the week ending May 10, 2015, according to the USDA's National Ag Statistics Service. Statewide there were only 2.5 days suitable for fieldwork. Operators in eastern Iowa reported weeds are getting ahead of the sprayers as farmers were unable to get into fields to spray. Activities during the week included planting, fertilizer and herbicide application, and seedbed preparation.

As of May 10 corn planting in Iowa is now 83% finished
Topsoil moisture levels rated zero percent very short, 7% short, 82% adequate and 11% surplus on Sunday May 10. Subsoil moisture levels rated 2% very short, 10% short, 82% adequate and 6% surplus. North central and southwest Iowa reported the highest topsoil moisture levels with 99% of the fields rated adequate to surplus. Southwest Iowa reported the highest subsoil moisture at 98% adequate to surplus.

In Iowa, 83% of the corn crop has been planted as of May 10, approximately one week ahead of both last year and the state's 5-year average. Southwest Iowa is lagging behind, with just 64% of its corn planted, compared to the highest district, northwest Iowa, where 96% of the corn was in the ground as of May 10.

Iowa's 2015 corn crop is 29% emerged, a week ahead of last year
Also as of May 10 in Iowa, 29% of the state's 2015 corn crop has emerged, just over one week ahead of last year. Corn emergence is described as excellent with reports of high stand counts in some areas. Soybean planting reached 30% complete, 5 days ahead of 2014, and 3 days ahead of the average.

Iowa's oat crop is now 98% planted, 10 days ahead of last year, and one week ahead of normal. Oats emerged has reached 83% for the state, 9 days ahead of last year, and 5 days ahead of normal. The season's first oat condition ratings came in on May 10 at zero percent very poor, zero percent poor, 21% fair, 68% good and 11% excellent.

Limited progress has been made on the first cutting of alfalfa hay due to the cool, wet weather. The first hay condition rating of the 2015 season for Iowa shows zero percent very poor, 1% poor, 21% fair, 60% good and 18% excellent. Pasture condition as of May 10 improved to 67% good to excellent. Livestock conditions are mostly normal with continued reports of cattle being turned onto pasture. Muddy lots are reported by some cattle producers in southwest Iowa. Meanwhile, poultry producers remain concerned about their flocks given the recent spread of avian influenza.
