The percentage of Iowa’s corn and soybeans rated good or excellent declined at least 7 points last week, the largest such drop this year, according to the U.S. Department of Agriculture.
The latest USDA report said 66% of the state’s corn and 63% of soybeans were good or excellent, down from 73% and 71% a week ago.
Widespread moderate to severe drought conditions are affecting southern Iowa, where the available soil moisture for crops is dwindling. Less than 10% of topsoil and subsoil in southwest Iowa has adequate moisture, according to the USDA.
In northeast Iowa, 90% of the soil has adequate or surplus water. In the past two weeks, northeast Iowa has had above-average rainfall and southwest has been abnormally dry.
The state as a whole received less than half the rainfall of what is typically expected last week and less than half the state has adequate soil moisture.
The area of worst drought is still in northwest Iowa near Sioux City.
