Nearly 1000 'citizen scientists' sent in their observations this year on Soil Animal Days 2019. And a surprisingly high number of people tried to do something in return for the vital services these soil creatures provide for us.

The visit included a tour, an introduction to NIOO's three major research themes, and a number of hands-on ecological measurements and experiments in which the King took part.
