How big is the average alfalfa & hay operation in Idaho?

USDA's 2022 Census of Agriculture reports about 140 harvested acres of alfalfa & hay per operation in Idaho, averaged across 7,480 farms (1,047,568 acres total).

Is average operation size the same as field size?

No — and it's the most common mix-up. The 140-acre figure is the average alfalfa & hay 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 140-acre alfalfa & hay field by drone in Idaho?

Roughly $1,646–$2,744 for a single application (about $12–$20/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 alfalfa & hay field?

Measure your actual alfalfa & hay 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 Idaho 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 alfalfa & hay in Idaho.
Request free quotes. Send your mapped field to drone operators serving Idaho to receive real, no-obligation quotes.
