Severe weather conditions rolled through Iowa during the week ending June 28, as high winds, isolated hail and heavy rain occurred, with excessive moisture stressing some crops and causing small drowned-out areas, preventing farmers from controlling weeds, according to the June 29 Crop & Weather report.

"Spraying weeds, sidedressing fertilizer, making hay and other activities were all slowed by the wet weather," said Iowa Agriculture Secretary Bill Northey. "Some farmers in southwest and south-central Iowa may be forced to take prevented-planting coverage (for any remaining corn and soybean acreage) on some fields they will not be able to plant before July 1."

State Meteorologist Harry Hillaker said torrential rains fell over portions of central and south-central Iowa that week, with widespread flooding. "However, parts of northwest and southwest Iowa saw only light amounts of rain, with Sidney and Shenandoah recording only sprinkles," he added.

The report stated 83 percent of corn was rated good to excellent. Soybean emergence reached 96 percent, 11 days behind 2014, with soybean condition 78 percent good to excellent.

With 90 percent of oats headed or beyond, the report said conditions declined slightly to 81 percent good to excellent. Moreover, hay condition fell to 70 percent good to excellent, with the first cutting of alfalfa reaching 83 percent complete and second cutting 9 percent complete.

Laura Cunningham, marketing coordinator for Latham Hi-Tech Seeds, said, "The heavy rain and wind that came through during the first part of the week has left fields with standing water, and even flattened some," with some regional sales managers citing yellow flash.
