Weed control in secondary archaeological sites by means of precision agriculture techniques

The development of intervention approaches that lessen biodeterioration and enable the realization of cultural heritage is crucial for the improvement of secondary archaeological sites. A challenge faced by tiny archeological sites is the emergence of spontaneous vegetation, particularly ruderal plants. Here, we describe the development of a weeding system that applies precision agriculture techniques. Drones will be used to identify vegetation that is considered noxious and to apply herbicides where and when they are really needed. Additionally, the efficacy of the treatments can be tracked by using a multispectral sensor.
