The textural soil data is a harmonized and structured data set with information
related to soil particle-size fractions (PSF) such as clay, sand, and silt, as transformed
data. The transformed data was obtained through additive log-ratio transformation because the
PSF are compositional data. The textural soil data was fitted to five standard depths using
the quadratic function with equal areas (spline). Standard depths were: 0 - 5 cm, 5 - 15 cm,
15 - 30 cm, 30 - 60 cm, and 60 - 100 cm. The original data was obtained from Sistema de
Información de Suelos de Latinoamérica y el Caribe - SISLAC, a soil information system
developed by the Food and Agriculture Organization of the United Nations.
