Flying Solutions for More Efficient Farming: Drone or Tractor?

A drone does not replace every other spraying method; it delivers the best results when used in the right place. Here we compare drones, tractor sprayers and knapsack sprayers under real field conditions.

Capacity and Timing

Tractor sprayers offer high capacity on dry, flat fields, but refilling takes time and they cannot enter wet soil. Knapsack sprayers suit small areas and spot treatments but have very low capacity. Drones work regardless of soil conditions, even after rain or irrigation. As one farmer put it, a drone can finish 4 hectares while an 800-litre sprayer is being filled.

Water Use and Logistics

Tractor applications use a lot of water per hectare and often need a second vehicle to carry it. Drones typically need 10-30 litres per hectare, which matters a lot far from water sources.

Field Conditions

• Slopes and terraces: tractors risk rollover; drones follow the terrain with radar.
• Rice and flooded fields: almost impossible for tractors.
• Late-season applications: tractor wheels crush tall crops; drones do not.

Operator Health

With knapsack sprayers, the operator is in direct contact with chemicals. With drones, the pilot stays outside the treated area, though protective equipment is still required when mixing.

Drone Limitations

• No spraying in windy weather.
• Some labels require water volumes unsuitable for drones.
• Initial investment must be weighed against annual area.

Which When?

On large, flat, dry fields tractors remain effective, and FJD AT2 auto-steering improves their precision. Drones excel in wet, sloping, flooded or late-season work and time-critical disease control. Many farms use both.
