Rocky ground above the sea, terraced olive groves on Brac and Solta, narrow plots in the Neretva valley hemmed in by canals. These are terrains where conventional machinery struggles, and every tractor pass or manual task on a slope drains time and energy. This is exactly where a drone for an olive grove and a drone for an orchard show their greatest advantage: they work from above, do not compact the soil, do not depend on access roads, and cross a terrace as easily as a flat plot.
This article explains what is legal to do by drone in olive groves and orchards today, where the real benefit lies on Dalmatia’s difficult terrain, and where we stand on the spraying question many growers ask about.
Why difficult terrain
Olive groves on the rocky ground of Brac and Solta are often split by dry-stone walls into small terraces at different heights. Neretva mandarin and other citrus orchards are laced with canals and embankments. In both cases a drone is indifferent to slope or to plots being separated.
- No soil compaction or root damage on narrow terraces.
- Access to parts of a grove that are hard to reach on foot.
- Even coverage regardless of the gradient.
- Faster inspection of a large but fragmented area from a single point.
For groves on Peljesac, Hvar, Korcula and in the Neretva, this means work that would take days on foot is done in one visit. More on our approach to specific terrain is on the difficult terrain page.
What is legal to do by drone today
The greatest value of a drone in permanent crops lies in monitoring and feeding, and everything below is fully permitted in Croatia provided flight rules are respected.
Mapping and orthophoto
The drone photographs the grove from the air and produces a precise orthophoto plan. You get the exact area of each plot, the tree count and an overview of the state of terraces and dry-stone walls. This base map supports work planning and applications. Mapping is available from 20 EUR/ha.
NDVI vitality monitoring
A multispectral camera measures crop vitality and reveals zones of weaker growth before they become visible to the naked eye. In olive groves this helps catch drought stress or a problem in a particular terrace early, and in citrus it flags uneven development. NDVI monitoring starts from 30 EUR/ha. Details are on the mapping and monitoring page.
Foliar feeding
The drone can precisely apply permitted foliar fertilizers and biostimulants to the canopy. This is legal and very practical exactly on terraces that a ground sprayer struggles to reach. Foliar feeding starts from 45 EUR/ha, and from 65 EUR/ha on demanding terraced terrain. Irrigation and the spreading of permitted materials are also possible.
The flight itself is always carried out under the rules of the Croatian Civil Aviation Agency, with a registered operator and the required permits.
What about pesticide spraying?
We get this question most often, so let us be clear and honest. Spraying crop-protection pesticides from a drone is currently not permitted in Croatia or the EU. A drone that sprays a product is legally treated as an aircraft, and aerial application of pesticides is prohibited under the Act on the Sustainable Use of Pesticides (NN 32/20) and Directive 2009/128/EC. On top of that, no registered plant-protection product in Croatia is approved for aerial application.
For these reasons we do not spray pesticides by drone, nor do we offer it as a service. There are signs that a reform of EU rules (2025/2026) could ease these restrictions, but that remains uncertain for now. If you would like us to notify you the moment the rules change, register your interest and we will add your grove to the list. We explain the legal framework and status in detail on the drone spraying page.
Visit pricing and examples
Beyond the per-hectare rate, it helps to know the cost framework for a visit:
- Half-day visit from 450 EUR, full-day from 850 EUR.
- Minimum fee 120 EUR, waived for groves larger than 3 ha.
- Travel cost 0.80 EUR/km for distances over 30 km.
For a small two-hectare olive grove on Solta it usually makes sense to combine mapping and NDVI monitoring in a single visit, while for larger Neretva orchards a full-day visit comes into its own. The full price list is on the pricing page, and an overview of our offer on the services page.
Which crops we serve
We work on permanent crops across Dalmatia: olive groves, orchards and citrus and vineyards. Whether your crop sits on rocky ground, a terrace or a lowland valley, we adapt the flight and the service to your terrain.
