According to the report summary:
Activities for the week included cutting hay, chopping corn silage, harvesting oats for grain, spraying for aphids, and moving grain.
Topsoil moisture levels rated 7 percent very short, 14 percent short, 70 percent adequate and 9 percent surplus. Subsoil moisture levels rated 8 percent very short, 16 percent short, 70 percent adequate and 6 percent surplus. In spite of recent rains, subsoil moisture levels in south central and southeast Iowa continue to remain critically low with greater than 90 percent rated short to very short.
Ninety-two percent of the corn crop has reached the dough stage or beyond, eight days ahead of the five-year average. Corn dented was at 63 percent, nine days ahead of last year. Seven percent of the corn crop was mature, nine days ahead of average. Seed corn harvest has begun. Corn condition rated 73 percent good to excellent.
