By Staff | May 29, 2013

Young corn plants pop up on May 24 in this field along U.S. Highway 3 between Gilmore City and Pocahontas. As of May 27, the USDA-NASS said 85 percent of the state's corn had been planted, and 54 percent had emerged.

Dry conditions early in the week ending May 26 permitted Iowa farmers to make progress planting crops according to the USDA, National Agricultural Statistics Service. As the week continued, rainfall across much of Iowa brought a halt to field activities.

There was a wide range of days suitable for fieldwork across Iowa, with North Central Iowa having less than one day suitable, and South East Iowa having four days suitable.

Statewide there was an average of 2.3 days suitable for fieldwork during the week.

Flooding and soil erosion were reported in many areas of the state.

Farmers were concerned about standing water after precipitation received during the weekend.

Topsoil moisture levels rated 0 percent very short, 1 percent short, 45 percent adequate and 54 percent surplus. This is the highest surplus rating for topsoil moisture conditions since June 2010. Subsoil moisture levels rated 1 percent very short, 7 percent short, 63 percent adequate and 29 percent surplus.

Eighty-five percent of Iowa’s corn acreage had been planted, behind the five-year average of 98 percent.

Fifty-four percent of the state’s corn crop has emerged, well behind last year’s 93 percent and the normal 81 percent.

Soybean planting was 40 percent complete, behind last year’s 95 percent and the five-year average of 83 percent. Eight percent of the soybean crop has emerged.

Oat emergence was nearing completion with 92 percent of the crop emerged. Oat condition was rated 1 percent very poor, 4 percent poor, 29 percent fair, 57 percent good and 9 percent excellent.

Pasture and range conditions rated 2 percent very poor, 9 percent poor, 28 percent fair, 47 percent good and 14 percent excellent.
