The national average for drone spraying is $12–$18 per acre for field crops (corn, soybeans, wheat) with the farmer supplying the chemical product. Specialty crops like vineyards and orchards typically run $20–$35/acre due to the canopy complexity.
| Crop | Low | Average | High |
|---|---|---|---|
| Corn | $12/acre | $15/acre | $18/acre |
| Soybeans | $12/acre | $15/acre | $18/acre |
| Wheat | $12/acre | $14/acre | $18/acre |
| Cotton | $14/acre | $16/acre | $20/acre |
| Rice | $14/acre | $16/acre | $20/acre |
| Grapes / Vineyards | $20/acre | $27/acre | $35/acre |
| Orchards (tree fruit) | $20/acre | $27/acre | $35/acre |
| Cover crops (seeding) | $10/acre | $13/acre | $18/acre |
Rates are application-only. Chemical product is typically supplied by the farmer. Contact operators for exact quotes.
For a 1,000-acre corn farm with 3 applications per season at $15/acre: total annual cost is $45,000. Compared to a pull-behind ground sprayer, drone application eliminates soil compaction losses estimated at 3–5% of yield — worth roughly $15,000–$25,000 per season on corn at current prices. Most growers recoup the cost difference within the first year.
Estimates based on industry benchmarks. Actual results vary by crop, field conditions, and season.

Most operators charge $12 to $18 per acre for application only, with the farmer supplying the chemical product. Rates vary by region, field size, terrain, and product type. Small or irregularly shaped fields typically cost more per acre than large, open tracts. Cover crop seeding runs in a similar range. These rates have dropped from $22 to $25 per acre just two years ago as more operators have entered the market.
A single commercial spray drone covers 20 to 50 acres per hour depending on the application rate, field layout, and drone model. Most operators using a DJI Agras T50 or Hylio AG-272 average 30 to 40 acres per hour in real-world conditions. Multiple-drone fleets increase throughput significantly.
University of Missouri Extension research shows the break-even between owning a DJI Agras T40 and hiring custom application is approximately 980 acres per year. For fewer than 1,000 acres, hiring custom application is typically more economical. For larger operations or those who offer services to neighboring farms, ownership can pay off within two to three seasons.
University research confirms it. Beck's Hybrids trials in Iowa and Nebraska showed drone-applied fungicide at 2 to 3 gallons per acre produced yields equal to ground rig applications at 15 to 20 gallons per acre. Purdue University found similar results for soybean fungicide. The lower carrier volume works because rotor downwash pushes droplets into the canopy.
Drones fly 8 to 15 feet above the canopy, while crop dusters fly at 50 to 100 feet or higher. Drones produce less drift, can spray at night, handle small and irregular fields, and do not require a runway. Crop dusters cover more acres per hour and carry larger payloads, making them better for very large open fields. Drone spraying costs $12 to $18 per acre compared to around $12 per acre for airplane application.
Key factors include field size (larger fields get lower per-acre rates), terrain (irregular or hilly fields cost more), product type (viscous or corrosive products may add a surcharge), distance from the operator's base, and season timing. Fields over 200 acres can often negotiate rates toward $12 per acre, while small fields under 40 acres typically run toward $18 per acre.
