SIOUX FALLS, S.D. (AP) -- Heavy rain, especially in eastern South Dakota, has made it difficult for farmers to complete their field work.

The U.S. Department of Agriculture said farmers in the state had an average of 3.6 days suitable for field work last week, and parts of eastern South Dakota received more than 2 inches of rain.

The heavy rain produced flooding in eastern South Dakota, but farmers in dry north-central and southwest parts of the state welcomed the rain.

About 73 percent of the state's corn crop rated in good or excellent condition. But only about 2 percent of the corn has been harvested.

The USDA estimates that 66 percent of the soybean crop is in good or excellent shape.

And 74 percent of the sorghum crop is in good or excellent condition.
