Geopedology as base information to forest suitability zoning in a catchment of norwestern patagonia, argentina
Geopedology at a semi-detailed scale (1:50.000) was carried out in Buta Mallín catchment which includes an area of 21.065ha, in the northwest of Neuquén province, Argentine Patagonia. Geopedology provides a spatial dimension of soil-landscape relations, which are displayed in a map and its legend, s...
