Description: Le réseau genevois d'observation des sols (GEOS) a pour objectifs le suivi à long terme de la charge des sols en polluants et plus généralement de leur qualité.
Il couvre l'ensemble des utilisations du sol du Canton (terres assolées, prairies permanentes, forêts, vignes, parcs urbains, autres). Il est constitué de 102 sites pour lesquels un prélèvement est réalisé à quatre profondeurs (0-20, 20-40, 40-60 et 60-80 cm). Chaque point est géoréféré. Ce réseau a été créé en 1990 et des campagnes de prélèvement ont été réalisées tous les 5 ans jusqu'en 2000. Après une interruption de 10 ans, le réseau a été réactivé par le GESDEC et modifié de sorte à surveiller aussi les sols urbains. Une campagne de prélèvement a débuté en 2010 et se terminera en 2015. Les analyses suivantes sont effectuées :
- Paramètres de caractérisation du site (granulométrie, pH, carbone organique, calcaire, CEC)
- Teneurs en éléments nutritifs (P, K, Mg, Ca)
- Teneurs en éléments traces métalliques
- Activité biologique et biomasse microbienne du sol (mesure d'ATP)
