Iowa's 2013 corn and soybean crops are developing slower than normal—thanks to the late start, delayed planting and wettest spring on record. While crops need some heat units to speed their development, the latest weekly survey by USDA shows this year's plantings are making some progress. The weekly Crops & Weather report, based on conditions as of June 30 and released July 1, shows 57% of the state's corn is currently rated good to excellent, and 56% of the beans are good to excellent.
"Statewide, crop conditions are looking better as of the end of June," notes Iowa Secretary of Agriculture Bill Northey. "And it's great to make progress in planting, as 99% of Iowa's corn and 96% of the soybeans are now planted. But while our crops are looking better than they have been in recent weeks, they are still running behind in maturity and development for this time of the growing season."
Nationally, the condition of the U.S. corn crop is rated 67% good to excellent as of the end of June. For soybeans nationally, USDA reports 67% of the crop is in good to excellent condition. The weekly Iowa Crops & Weather report is available on the Iowa Department of Ag & Land Stewardship's site or USDA's site. The report summary follows here:
Iowa's 2013 corn crop is rated 44% good and 13% excellent as of June 30
CROP REPORT: Warmer and mostly drier conditions during the week ending June 30, 2013 allowed Iowa farmers to near completion of corn and soybean planting, according to the weekly survey by USDA's National Agricultural Statistics Service. Statewide there was an average of 4.1 days suitable for fieldwork during the week, only the third week of the year with more than 4 days suitable. The 5.4 days suitable for fieldwork in Northwest Iowa were the most in the state, and Northeast Iowa had the least amount with 2.9 days suitable.~~~PAGE_BREAK_HERE~~~
Moisture levels for both topsoil and subsoil saw movement from the surplus rating into the adequate rating. Topsoil moisture levels rated zero percent very short, 1% short, 66% adequate and 33% surplus. Subsoil moisture levels rated zero percent very short, 2% short, 67% adequate and 31% surplus.
With 99% of the state's corn crop in the ground, Iowa farmers have virtually wrapped up planting. Statewide 96% of the corn crop has emerged as of June 30, about 3 weeks behind normal. The warmer weather helped the condition of corn and the good to excellent rating increased 3 percentage points from last week. Corn condition was rated 3% very poor, 11% poor, 29% fair, 44% good and 13% excellent as of June 30. Also, 96% of Iowa's soybean crop has now been planted, about two weeks later than it normally takes soybeans to reach that mark. The survey shows 89% of the soybean crop has emerged; 8 percentage points behind the 5-year average.

Soybeans also benefitted from the warmer weather, with condition ratings improving slightly, to 3% very poor, 9% poor, 32% fair, 45% good and 11% excellent. Eighty-four percent of the oat crop was headed on June 30, only 3 percentage points behind the normal 87% headed. And 7% of the oat crop has turned color, well behind last year's 63% and the 5-year average of 28%. Iowa's oat condition rates 1% very poor, 6% poor, 26% fair, 55% good and 12% excellent.
Farmers continued to make good progress harvesting alfalfa last week, and the 1st cutting of alfalfa now stands at 89% complete, 2 percentage points ahead of normal. Hay condition is rated at 1% very poor, 3% poor, 26% fair, 54% good and 16% excellent. Pasture and range conditions rate zero percent very poor, 4% poor, 24% fair, 48% good and 24% excellent.~~~PAGE_BREAK_HERE~~~
