The state of UAV adoption in Polish agriculture
Poland has roughly 14.4 million hectares of agricultural land — one of the largest farmed areas in the European Union. For the past decade, aerial scouting was handled almost exclusively by satellite imagery, which offered acceptable resolution for broad analysis but struggled with cloud cover, temporal lag, and the kind of sub-field granularity that agronomists actually need to act on.
By early 2026, an estimated 2,300 agricultural UAV operators held active BVLOS (beyond visual line of sight) permits issued by PAŻP, Poland's air navigation services agency. That number doubled from the 1,100 recorded at the end of 2023, driven mainly by cost reductions in multispectral sensor packages and a clearer permitting pathway introduced under EU U-Space regulation in 2023.
The regions with the highest drone operator density are Wielkopolska, Kujawsko-Pomorskie, and Dolnośląskie — all major cereal and rapeseed belts. Małopolska and Podkarpacie, where terrain makes tractor access difficult, are seeing faster growth in UAV services than any other region.
What multispectral sensors actually measure
The dominant sensor type on Polish agricultural drones is the five-band multispectral camera, capturing data in the blue, green, red, red-edge, and near-infrared portions of the spectrum. The output is processed into vegetation indices, of which NDVI (Normalised Difference Vegetation Index) remains the most widely understood, though NDRE (Normalised Difference Red Edge) has become preferred for monitoring nitrogen status in cereal crops mid-season.
A typical survey flight over 200 hectares at 80 metres altitude takes roughly 90 minutes using a fixed-wing UAV with a 15-kilometre range. The resulting orthomosaic is georeferenced to within 5 centimetres using RTK positioning, giving agronomists a map accurate enough to generate prescription files for variable-rate fertiliser spreaders.
NDVI versus NDRE: which to use when
NDVI saturates at high biomass levels — in dense wheat canopies during the grain-fill stage, it no longer differentiates between healthy and moderately stressed plants. NDRE, which uses the red-edge band, remains sensitive at higher leaf area index values and is better suited to late-season scouting.
Several Polish agrochemical advisers now recommend a two-flight scouting programme: one NDVI flight at stem extension (BBCH 31–33) to detect early nitrogen deficiency patterns, and one NDRE flight at flag leaf emergence (BBCH 37–39) to confirm fungicide timing decisions. The combined cost is typically 18–25 PLN per hectare when contracted through a regional drone service provider.
Early disease detection: what works and what does not
Detecting fungal disease from a drone is more complicated than it sounds. Fusarium head blight, one of the most economically damaging wheat diseases in Poland, produces pink discolouration of infected ears — visible in RGB imagery if the infection is severe. But by the time it is visible, the window for effective fungicide application has often passed.
Research conducted by Warsaw University of Life Sciences (SGGW) between 2022 and 2025 found that thermal cameras mounted on agricultural drones could detect Septoria tritici blotch 8–11 days before visible symptoms appeared, by measuring the slight temperature reduction in infected leaf tissue caused by altered transpiration rates. The study covered 340 plots across Mazovia and Łódź provinces.
The practical limitation is cost: thermal sensors capable of the 640×512 pixel resolution needed for meaningful canopy temperature mapping add roughly 15,000–25,000 PLN to a drone's equipment cost, putting this capability firmly in the professional-services tier rather than the owner-operator market.
Pest pressure mapping
Cabbage stem flea beetle and rape stem weevil damage patterns in oilseed rape are detectable in late winter and early spring UAV flights, when bare-soil damage tracks are visible from the air. Several Polish contract spraying firms have integrated this into their rapeseed monitoring packages, using the drone survey to generate GPS waypoints for targeted insecticide spot treatments rather than blanket field applications.
This reduces insecticide use per hectare and cuts costs for the farmer, but the practice requires BVLOS authorisation for large fields, which is still a significant administrative step for smaller operators.
Data management and farm connectivity
The bottleneck in 2026 is not the drone hardware but the data pipeline. A single 200-hectare multispectral flight generates 6–10 GB of raw imagery. Processing to a prescription map takes 45–90 minutes on a local workstation running Pix4D or Agisoft Metashape, or can be offloaded to cloud platforms such as DJI Terra, Trimble Ag Software, or the Polish-developed system AgroCloud PL.
Interoperability remains an issue. Prescription files generated from drone imagery need to be exported in formats compatible with specific tractor terminals — ISOXML is the standard, but coverage varies by machine manufacturer and model. Farmers working with older equipment often require a manual conversion step, which reduces the practical utility of sub-24-hour turnaround drone surveys.
Outlook for 2026–2028
The Polish Agricultural Advisory Centre (CDR) estimates that UAV-based crop monitoring could reach 1.5 million hectares annually by the end of 2028, driven by falling sensor costs and ongoing consolidation in the contract-services market. BVLOS regulation is expected to become somewhat more accessible under EASA's ongoing U-Space implementation review, which would lower the permitting burden for routine agricultural surveys.
The main remaining barriers are operator training — the new EU Part-BVLOS licence category requires both a theoretical exam and a practical assessment — and field-level data connectivity in the eastern provinces, where 5G coverage is still sparse and data uplink from remote field locations remains slow.
