Resumen
HERNANDEZ JIMENEZ, Alberto et al. PRESENCE OF SOIL PROPERTIES FERSIALÍTICOS vertices of the former province HAVANA. cultrop [online]. 2011, vol.32, n.1, pp. 63-74. ISSN 0258-5936.
The morphological characterization is presented with some physical and chemical results of two Fersialitic soil profiles studied in the former Havana province. In such profiles, it was proved that the vertic properties are shown in horizon B, due to the presence of 5-10-cm prismatic blocks covered with slickensides. These properties are formed as a result of a high content of clay, predominating minerals from the smectite group in the tropical subhumid climate of the region. Soils are moderately deep and made up of limestone rock. They are saturated and carbonated since the mid-lower part of the profile. The present functioning of this soil is related with the formation of this vertic horizon, which permits the soil surface loss when cultivated. The subtype vertic Reddish Brown Fersialitic soil is proposed to be included into the Fersialitic soils at the current issue of Cuban soil classification.
