A digital hydrologic soil group map for Argentina was built based on the drainage classes included in the INTA digital soil atlas of Argentina, scale 1:500,000. Soil shape files from all provinces were merged in a unique shape file for the whole territory and a field for Hydrologic Groups was created. The hydrologic groups (A, B, C and D) were assigned for all soil units according to the drainage classes: Group A to excessively drained, somewhat excessively drained and well drained soils; Group B to moderately well drained soils; Group C to imperfectly drained soils; and Group D to poorly and very poorly drained soils.
