Iowa County Corn and Soybean Yields
The USDA has released 2022 county crop yield data which can be seen in the maps below. The USDA did not report corn yields for Adams or Clarke County and did not report soybean yields for Adams or Wayne County. These yields were estimated based on historical yields and total unreported production.
The state average corn yield was 200 bushels per acre, down 4 bushels from 204 bushels per acre last year. County yields ranged from 138.6 bushels per acre in Clarke County to 230.8 bushels per acre in Delaware County. Emmet county had the largest year-over-year increase of 31.2 bushels per acre while Adams County saw the largest decrease of 49.0 bushels per acre. Again, note that yields in both Adams and Clarke County were estimated.
The state average soybean yield was 58.5 bushels per acre, down 4.5 bushels from 63.0 bushels per acre last year. County yields ranged from 37.9 bushels per acre in Decatur County to 69.1 bushels per acre in Scott County. Sac county had the largest year-over-year increase of 5.8 bushels per acre while Plymouth County saw the largest decrease of 24.6 bushels per acre.
