Black Soil A-Horizon Profiles – Catalonia, Spain

This dataset contains detailed information on the layers of horizon A (topsoil) of black soils collected in Catalonia, Spain. It includes 146 soil profiles characterized by the physical, chemical, and morphological properties of the topsoil horizon only.

The dataset includes the following variables:

Profile: Soil profile identifier
Column1 and Column2: Sampling point coordinates (UTM)
ID: Unique horizon identifier for each profile
Grouping: Classification by grouping based on soil properties.
Depth: Horizon depth (cm)
Value and chroma: Munsell color parameters
Coarse fragments: Percentage of coarse fragments
Sand, silt, clay: soil textural fractions (%)
pH: Soil pH in water
TOC: Total Organic Carbon (g/kg)
CaCO3: Calcium carbonate content (%)
CEC: Cation Exchange Capacity (cmolc/kg)
BS: Base Saturation (%)

These data were collected for research on soil classification, fertility, and distribution patterns. They can be used in pedological studies, soil mapping, cluster analysis, and statistical modeling of soil properties.
