Abstract

In northern Ecuador, soils of high altitude grasslands (páramos) are mainly non-allophanic andisols developed on Holocenic volcanic ash. These soils have a high water retention capacity and are the water tank of central Ecuador. To assess the effect of land use (burning and tillage) on soil hydrodynamic properties, rainfall simulation was conducted at 2 different sites (Pichincha near Quito and El Angel). Water repellency combined with the low bulk density of soil aggregates explain the intensity of sediment losses in the abandoned soils after cultivation
