Three webinars help build living labs for soil health

,
The initiative takes place within the European project NATI00NS. The three webinars, each with its own focus, are scheduled for June 22, June 29 and July 6. Common objective: to stimulate applications for EU Mission Soil calls and to develop Living Labs capable of developing repeatable actions in favor of soil health
