LINCOLN, Neb. (AP) — The summer heat continues to put stress on Nebraska’s crops, and some farmers have been forced to stop irrigating because of low river levels. 

The U.S. Department of Agriculture issued its weekly update on the state’s crops on Monday.

The USDA says the heat moderated a bit in Nebraska last week, but the state’s main crops still aren’t in great shape.

About 43 percent of Nebraska’s corn crop is in good or excellent shape. That’s well below the average for this time of year of 79 percent.

The soybean crop rates even worse with 34 percent in good or excellent condition. Normally, about 77 percent of the soybeans are in good or excellent shape.

The wheat harvest is now about three weeks ahead of normal and 97 percent done.
