Chilean Central Valley
Ñadi is a type of soil and a phytogeographic zone of Southern Chile. Ñadi soils are located in the Chilean Central Valley of Los Lagos Region, specifically between the moraines left by the region's most recent glaciation (the Llanquihue glaciation) and those of the penultimate glaciation (the Santa María glaciation). Ñadis have an impermeable layer, usually called "fierrillo".
