UPDATING THE CLASSIFICATION OF SOILS IN TABASCO, MÉXICO

Abstract

The files of existing soil studies from studies carried out in Tabasco, México, from the year 2007 to 2013, were gathered. With the support of the ArcGis software version 9.3, maps were designed with different scales until standardizing to 1:250 000. 153 soil profiles georeferenced with physical-chemical analysis were compiled, establishing with this the soil database. The soil classification was performed according to WRB version 2014. Nineteen (19) soil groups were determined in Tabasco, with Gleysols, Histosols, Fluvisols, Acrisols, Leptosols and Vertisols dominating. Soils were identified with very small cartographic units, which had not been reported in previous years, such as: Calcisols, Lixisols, Nitisols, Phaeozems and Tecnosols.
