PRELIMINARY SURVEY OF SOME SOILS FROM CHILEAN ALTIPLANO NEAR IQUIQUE

In the Altiplano of the Iquique Province, Chile, a study was carried out for the purpose of advancing in the knowledge of the soils in the zone, to determine the soil moisture and soil temperature regimes, and to establish its taxonomic classification. In one area, at the base of the slopes of the I...
