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.
In addition to the USDA NASS yield data available in this Information File, recent county yields from the USDA Risk Management Agency (RMA) for Supplemental Coverage Option (SCO) and Enhanced Coverage Option (ECO) are available in Decision Tool A1-44, SCO and ECO County Yield History for Iowa.
