The drought also has been intensifying in Kansas, the top U.S. producer of winter wheat. It also is entirely covered by drought, and the area in the worst stage rose nearly 4 percentage points to 34.5 percent as of Tuesday. Much of that increase was in southern Kansas, where rainfall has been 25 percent of normal over the past half year.
After a summer in which farmers watched helpless as their corn dried up in the heat and their soybeans became stunted, many are now worrying about their winter wheat.
It has come up at a rate on par with non-drought years, but the quality of the drop doesn't look good, according to the USDA. Nearly one-quarter of the winter wheat that germinated is in poor or very poor condition, an increase of 2 percentage points from the previous week and 9 percentage points worse than the same time in 2011. Forty-two percent of the plantings are described as in fair shape, the same as last week.
Farmers who might normally irrigate in such circumstances worry about low water levels in the rivers and reservoirs they use, and many are hoping for snow to ease the situation. But it would take a lot. About 20 inches of snow equals just an inch of actual water, and many areas have rain deficits of a foot or more.
