Iowa Corn and Soybean County Yields

This file includes county yield data for corn and soybeans in Iowa summarized from USDA NASS yield reports. Included in the tables are: the most recent yield, the 10-year average, and the high and low yield in the past 10 years. All values are bushels per acre, per year.

This information is helpful in developing corn and soybean budgets, cash-flow projections, or other types of analysis for farmers where the actual production history is not available. These tables are presented in the accompanying "pdf" file that you can access by clicking here or on the icon above.
