These days, a new original form of farming is getting more and more attention: the use of drones to improve productivity. The machines can indeed provide a top-down imagery that can then be used by the farmers to spot weeds and their spreading early in the season and thus address the issue better and earlier, or to check if plants receive enough water and nutrients thanks to infra-red shots. They could also be used to locate the areas with the most input is needed for a given year, which would inevitably lead to healthier crops and a better yield for the farmer. The patterns seen from the sky can help detect problems in the irrigation system, soil variations and pest and fungal infestations in the crop. The collection of imagery will eventually lead to better crop management, thus increasing productivity and revenues for the farmer.
