Equipped with sensors, drones capture high-resolution images of crops and create detailed maps of fields to monitor crop health over time, they also provide information to farmers to help them make better decisions about irrigation and fertiliser application or pest management. Any high-resolution images of fields also reveal bacterial infections and diseases or pest invasions on crops. Drones are also equipped with spraying equipment and apply pesticides and fertilisers precisely and efficiently therefore reducing waste and improving yields in specific parts of fields. In addition, they are also used to monitor livestock including counting cattle or checking on their health and welfare.
