How big is the average soybeans operation in Iowa?

USDA's 2022 Census of Agriculture reports about 258 harvested acres of soybeans per operation in Iowa, averaged across 36,754 farms (9,497,898 acres total).

Is average operation size the same as field size?

No — and it's the most common mix-up. The 258-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 258-acre soybeans field by drone in Iowa?

Roughly $2,064–$4,644 for a single application (about $8–$18/acre, application only — product is extra). Extra passes, higher carrier volume, or restricted-use products raise it. Use the calculator above to adjust.

How do I measure my exact soybeans field?

Measure your actual soybeans field

Averages are a planning starting point — your field is its own size. The field mapper turns satellite imagery into exact acreage in four steps:

Open the field mapper. Go to the Ag Drone Sprayers field mapper and search your address in Iowa or pan the satellite map to your field.
Trace the boundary. Tap each corner of your field to drop pins; the tool closes the polygon and computes geodesic acreage.
Read acreage and cost. See your field's exact acreage and an instant drone-spraying cost estimate for soybeans in Iowa.
Request free quotes. Send your mapped field to drone operators serving Iowa to receive real, no-obligation quotes.
