La clasificación de suelos de Cuba: énfasis en la versión de 2015.

Cuba is among the few countries that have developed its own soil classification system, the latest version, 21 years ago, so it is necessary to review and update it. This update should be on the basis of the new results in soil classification in the world. So that, in our paper we are taking in account the historical principle (that is the name of the soils, and the genetic geographic basis) and with the information available, try to improve the soil classification with the establishment of diagnostics profile. In our soil classification system for Alitic, Ferritic, Ferralític Ferralic and Histosol is prepare dagnostic soil profile until soil subtypes. In the case of Fersiallitic, Siallític Brown, Siallitic Humic, Vertisols, Fluvisols, Halomorphic and Few Developed Soils Groups, diagnosis profile is stablished until genus level. This classification results a Soil Taxonomy until soil subtypes or soil genus, unlike the previous classifications. We are applying also the anthropic influence in the change of soil properties, with new agrogenic and erogenic soil subtypes. In the Group of Anthrosol there are new soil types and there is a new soil group named Tecnosol with two soil types. The name of Hydromorphic soil group is changed by Gleysol and there is a new soil subtype named slitic. This version has 15 groupings, 39 genetic types and 197 subtypes of soils.
