Toledo Chronicle, Tama News-Herald

DES MOINES - Iowa Secretary of Agriculture Bill Northey commented on the Iowa Crops and Weather report released by the USDA National Agricultural Statistical Service. The report is released weekly from April through October.

"Harvest is starting to pick up speed with five percent of both the corn and soybean crop now out of the field. Early reports from farmers show yields vary widely across the state," Northey said. "It is likely the pace of harvest will continue to increase as the warm dry weather has helped the crop dry down in the field."

Subsoil moisture levels rated 41 percent very short, 39 percent short, 20 percent adequate and 0 percent surplus. Southeast Iowa remained the driest with over 50 percent of the topsoil moisture rated in the very short category.

Ninety-five percent of the corn crop had reached the dented stage or beyond, 3 percentage points behind normal. Sixty-one percent of corn was mature, behind the normal 76 percent. Only five percent of the corn had been harvested for grain or seed, two weeks behind normal. Moisture content of all corn in the field was estimated at 28 percent while moisture content of corn harvested was estimated at 23 percent. Corn lodging was rated at 71 percent none, 22 percent light, 6 percent moderate and 1 percent heavy. Corn condition was 8 percent very poor, 18 percent poor, 38 percent fair, 32 percent good and 4 percent excellent. Eighty-eight percent of soybeans had turned color, 8 percentage points behind normal. Fifty-one percent of the crop had dropped leaves, 9 days behind normal pace.
