SIOUX FALLS, S.D. (AP) The weekly crop report from the U.S.

Department of Agriculture says South Dakota's Corn harvest is 88 percent complete, compared to 75 percent the previous week.

The sorghum crop is 94 percent harvested, and sunflowers are 83 percent harvested.

The five-year average shows that all three crops should be virtually done by now.

Farmers report that the drying time is the biggest block to the corn harvest. The report says some of the crop won't be picked until the ground is completely frozen.

Ag officials say there's a big demand for crop drying this year and that farmers either will pay the cost of having a dryer at their farm or a higher drying cost at their grain elevator.

Experts say the corn is wetter than it has been in many years.
