  • How much area can a spray drone cover per hour?
    Depending on tank size and product rate, single units typically treat 15–25 acres (6–10 ha) per hour; paired drones double that throughput. DJI Agras T50 can achieve 50 acres per hour with optimal conditions.
  • How accurate are spray drones compared to ground sprayers?
    With RTK GPS and flow-rate sensors, modern spray drones routinely hit sub-meter accuracy, reducing overlap and skips better than many tractor-mounted booms.
  • Do drones work in windy conditions?
    Most platforms operate safely in steady winds up to 25 km/h; SkyFlow monitors real-time wind and auto-adjusts flight speed and droplet size to maintain coverage.
  • How much does drone spraying cost for agriculture?
    Costs vary with acreage, product rate, and crop stage, but average CA $15-20 per treated acre—often offset by reduced chemical use and higher yields. Sports turf management usually has a higher per-acre rate due to specialized equipment, algorithms, and skilled pilots required for complex geometries.
  • Are spray drones safe for the environment?
    Yes, spray drones are environmentally friendly. Precision placement and lower spray volumes mean less chemical runoff, reduced soil compaction, and minimal disturbance to beneficial insects.
  • What is drone spraying?
    Drone spraying, also known as UAV crop spraying, uses unmanned aerial vehicles equipped with precision nozzles to apply fertilizers, pesticides, or wetting agents quickly and evenly across fields and turf.
  • Can drones apply granular products?
    Yes. Granule spreader hoppers handle fertilizers, cover-crop seed, and beneficial insects with distribution uniformity rivaling pneumatic spreaders.
  • What crops can be treated by drones?
    Drones can treat a variety of crops including cereals, canola, corn, soybeans, specialty vegetables, orchards, vineyards, and sports-turf grasses. All benefit from aerial micro-dosing and spot treatments.
  • What droplet sizes can drones produce?
    Swappable nozzles let operators generate 50–500 microns droplets, matching label requirements for systemic and contact chemistries.
  • Is drone spraying legal in Canada?
    Yes. Operators must hold a Transport Canada RPAS Advanced Certificate with SFOC, comply with the Pest Control Products Act, and follow provincial pesticide-applicator licensing rules.
  • How does variable-rate drone spraying integrate with my existing precision-ag maps (NDVI, soil EC, yield)?
    SkyFlow converts your geo-referenced zones into flight scripts, adjusting spray volume nozzle-by-nozzle to match crop need and reduce input spend.
  • Can drones spot-spray herbicide-resistant weed escapes in cereal crops?
    Yes. Vegetation Index maps can identify individual patches; only spray where's needed, cutting herbicide use up to 90 % versus blanket spraying.
  • What’s the minimum spray volume a drone can deliver without risking leaf scorch?
    Drone spraying with more concentrated chemicals compared to traditional ground sprayers due to it's centrifugal nozzles and propeller down wash. Usually 5 to 10 times concentrated compare to the ground-way concentration.
