"The warm weather has helped crop progress, but the severe storms that have also struck the state have caused isolated damage," Northey said. "In addition, the high heat and humidity can cause stress for livestock, so it is vital farmers remain attentive to cattle that are out in the heat." Agricultural Summary: Temperatures during the last week of spring welcomed the official start of summer. Most of Iowa saw temperatures rise above ninety at times last week. Corn and soybean growth progressed nicely with corn starting to green up and canopy open ground. While farmers welcomed the heat, many producers need a break in the rains which again slowed hay harvest and weed control efforts. The heat, though beneficial, came with a price as severe thunderstorms brought crop-damaging winds and hail to some fields. Although severe weather caused some crop damage in isolated cases, the State's corn and soybean crop received more than favorable growing conditions to begin summer. Flooding concerns continue in the Southeast district of Iowa. There were 2.2 days suitable for fieldwork during the week, compared to the five-year average of 4.9 days. Topsoil moisture rated 1 percent short, 64 percent adequate, and 35 percent surplus across the state. Subsoil moisture rated 2 percent short, 65 percent adequate, and 33 percent surplus. Field Crops Report: Nearly all of Iowa's corn acres have emerged. Corn condition was rated 1 percent very poor, 2 percent poor, 16 percent fair, 58 percent good, and 23 percent excellent.
