In the Callejon Interandino (the plateau between the two cordilleras), where eroded volcanic soils (cangahua) are present, a survey has been done to estimate the proportion and methods of reclamation of these soils. Other topics such as family struct

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 bott

This study concerns the indurated horizons of some volcanic ash soils in the Interandine Valley of the Ecuador. These indurated horizons were cropped out by erosion on the piedmont of the sierras, under a subarid to subhumid climate, and then they ha
