La Cl\u00e9 des Sols is a collective work coordinated by Sophie Cornu, soil scientist, research director at INRA\u00e9, based at CEREGE in Aix-en-Provence. The texts were written by pupils from CM2 and 6e classes and the illustrations were created by these same pupils, as well as those from CE1 and CM1 classes from schools in Marseille.<\/p>\n
