Preliminary rainfall figures show June was Iowa's third wettest in the 141 years records have been kept, and all that much rain is damaging crops.
It's too early to tell the extent of damage from rain, hail and wind from the numerous thunderstorms in recent weeks. Farmers in some locations are reporting significant field flooding.
The most recent crop condition report released Monday shows 79 percent of the state's corn crop in good or excellent condition and another 22 percent is fair. Soybeans are faring nearly as well with 75 percent good or excellent and 19 percent fair.
Those conditions likely will change.
Iowa State University agronomist Mark Westgate says Tuesday the yield per acre for corn and soybeans will be reduced. It's just too early to say how much.
