How big is the average soybeans operation in Illinois?

USDA's 2022 Census of Agriculture reports about 307 harvested acres of soybeans per operation in Illinois, averaged across 33,243 farms (10,213,710 acres total).

Is average operation size the same as field size?

No — and it's the most common mix-up. The 307-acre figure is the average soybeans acreage per farm; most farms split that across several fields, so a single field is typically smaller. For a real field boundary, trace it on satellite with the field mapper.

How much does it cost to spray a 307-acre soybeans field by drone in Illinois?

Roughly $3,070–$5,526 for a single application (about $10–$18/acre, application only — product is extra). Extra passes, higher carrier volume, or restricted-use products raise it. Use the calculator above to adjust.
