Drone usage is a developing market in New Zealand and while not widely used yet, the potential is there. As technology advances, drone applications will improve, better cameras, larger payloads and greater range will only increase the services and efficiencies farmers need.
Warrwick Funnell from Agdrone says, convincing farmers initially that drones “were tools and not toys” has been one of the hurdles.
Farm drones that are used for various agricultural applications are Unmanned Aerial Vehicles, or UAV’s, are highly technical and cost 10’s of thousands of dollars and require licencing and certification from the Civil Aviation Authority for their commercial usage.
Currently, most drones for agricultural use are medium-sized usually for analysis applications, while larger drones are used when there is a need to carry a load for planting or spraying applications. Like most industries currently using drones, multi-rotor configurations are the favourite in agriculture, likely due to their lower cost and high level of simplicity and ease to operate.
Funnell’s service is mostly focused on weed control or spot spraying in both pasture and pockets of woody weeds like gorse, broom and blackberry on difficult terrain.
The versatility of drones provides many different avenues for improving existing agricultural processes including soil and field analysis. Drones are able to produce 3D maps quickly and cheaply, which are then used for the design of seed-planting patterns and the generation of a wide range of data types with many applications; for example, nitrogen-level management.
Drones have the ability to monitor crops accurately, frequently and affordably, delivering high quality data that is updated regularly to provide insight into crop development and highlight inefficient or ineffective practices.
Drones can also be used to generate multispectral images of crops which are then analysed to track changes in health and maturity. The ability to assess the health of a crop quickly and precisely can be invaluable for farmers. If for instance a bacterial or fungal infection is identified, early detection allows for quick action to be taken in order to remedy the issue.
The are substantial benefits for the sheep and beef farmer, and we already are seeing some farmers use drones to check livestock, water troughs, fences, feed covers and use audio with a dog bark to muster stock.
So as technology advances, drones have the potential to change the way farmers operate and improve efficiencies and outcomes - and of course the low carbon footprint of drones can only further support the good work being done by farmers to reduce emissions.
