The national drought monitor report released Thursday says in Iowa, the nation’s largest corn producer, severe drought spread to nearly 42 percent of the state up from 32 percent a week ago.
The drought monitor tracks conditions from Sept. 3 through Tuesday morning.
The U.S. Department of Agriculture says about a third of corn and soybeans are in good or excellent condition in Iowa down from more than half rated in those categories a month ago. In Nebraska, where drought increased in some areas, non-irrigated corn is in similar shape.
Drought worsened in portions of Illinois, Indiana, Kansas, Minnesota, Missouri, and Wisconsin.
Further south, conditions in Arkansas, Louisiana, Mississippi, Oklahoma, and Texas declined.
