Elaisian has developed the world's first precision agriculture service that prevents the diseases of olive trees and vineyards. By a system of algorithms based on a database of agronomic studies, it is able to prevent diseases and optimize cultivation processes such as irrigation and fertilization.Elaisian has created a weather device that records climate data in real time from each field. Through the study of these data, the work of algorithms and satellite images, the service provides alerts to optimize the use of water in the field, improve the use of fertilizers and prevent diseases, thus reducing costs during the pre-harvest phase and improving production.To date, over 1000 farms in 10 countries around the world use the Elaisian system and are able to: reduce treatments, do them only when necessary, reduce costs, improve the quality of the final product and finally monitor their field 24 hours a day.
