Les EVCC sont des cultures à croissance rapide qui couvrent et protègent le sol, et sont laissées comme paillage ou enfouies pour enrichir le sol. Les légumineuses sont privilégiées pour leur capacité à fixer l’azote. Elles peuvent être semées, mais certaines forment des racines au niveau des nœuds et peuvent être établies à partir de boutures. ECHO ne fournit pas d’inoculum pour les légumineuses. Une note technique d’ECHO est disponible à propos des Engrais verts cultures de couverture.
