Indurated volcanic soils are located in the North of the interandean basin. Soils are distributed according to a climatic toposequence. The indurated horizons (cangahua) are located in paleosoils. Their hardness is very high in dry areas, at the bottom of the soil sequence, and lower in high altitude areas which are more hunid. The soils with cangahua at less than 20 cm depth cover about 80,000 hectares. (Résumé d'auteur).
