There are pockets of the state, however, like west central Iowa, that are too dry and corn leaves are starting to curl. Other areas are too wet, particularly after last week’s isolated heavy rains. North Liberty got the most rain last week — a soaking of nearly 7.5 inches.
Still, the U.S.D.A. has rated 79 percent of Iowa’s corn crop in good to excellent condition. Seventy-seven percent of soybean fields are in good to excellent shape.
