Soil characteristics in the Nipe-Sagua-Baracoa mountainous region. I. Allitic, Ferritic and Ferralitic soils
Main Article Content
Abstract
Baracoa mountainous region, which occupies an area of 5 380
km2, with the objective of studying the characteristics of
different soil types and subtypes in relation with the new Cuban
soil genetic classification. At the same time it was necessary
to elaborate a soil map in scale 1:100 000, to determine soil
characteristics together with the map. Results of different works
conducted in the region were taken into account, specially the
information about 1 400 soil profiles from the map 1:25 000 at
the Provincial Soil and Fertilizer Management offices of
Guantánamo and Holguín. Among the most important results
are the diagnosis, classification and extension of nine soil
groups, 16 types and 32 subtypes according to the new Cuban
soil classification. This work also offers the area and
characteristics of the three most developed soil groups in the
region: Allitic (3 600 ha), Ferritic (80 544 ha) and Ferralitic (68 702 ha),
besides characterizing the unsaturated humic Ferritic subtype,
which is proposed as a soil classification contribution.
