How big is the average sorghum operation in South Dakota?

USDA's 2022 Census of Agriculture reports about 327 harvested acres of sorghum per operation in South Dakota, averaged across 584 farms (191,216 acres total).

Is average operation size the same as field size?

No — and it's the most common mix-up. The 327-acre figure is the average sorghum 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 327-acre sorghum field by drone in South Dakota?

Roughly $2,616–$5,886 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 sorghum field?
